Hello dear Cats. I decided to build a 12-220 converter on hand was the UPS igpon 250w and a colo 500 VA, took out the dead acum soldered wires authentic, connected to auto acum all plowing gud. but after 5 minutes, the UPS turns off and have to start in advance. suggest how to bypass this protection mode? ZS Please don’t kick me if the topic is repeated… Throw out all the electronics except the switches and transformer, make your generator on IR2153. It should give you about 200w. _________________ If you are unhappy with your standard of living, the laws of our country, the price level, remember all this at the next election. PCB assembly from $30 + FREE shipping worldwide + stencil Need to turn off Green Power feature Green Power feature, prevents the UPS from running idle. Shuts down the UPS after 5 minutes if the load is less than 10% of the UPS rating. http://www.ippon.ru/support/hot/90016/ High quality at a competitive price allows MORNSUN DC/DC converters to compete with counterparts from leading global manufacturers.

It should give you about 200w. Why, if everything works fine and has overdischarge protection for the battery. And not all UPS have no no-load cutoff function. And nothing overheats, if output current is exceeded, it will turn off. _________________ Oh, how many wondrous discoveries the enlightened spirit prepares for us. “When society has no color differentiation of pants, there is no purpose!” The best is the enemy of the good. Don’t forget to put a cooler on the whole thing, because the battery used to go down faster than the whole thing warms up. Don’t compare it to a non-branched inverter, they usually put a cooler there. How many times I did APC BE525-RS nothing overheated.
_________________ Oh how many wondrous discoveries the enlightened spirit prepares for us. “When society has no color differentiation of pants, there is no purpose!” I have exactly the same APC and it heats up a lot even with the regular battery!!! After 7-10 minutes of running on battery power at about half load, you can not touch the transaxle, the same with all cyber power So it’s faulty if it overheats. I do not. Sold about 6 already. There’s a full load of 300 watts. So it’s 150 watts of heat? Oh, goody. _________________ Oh, how many wondrous discoveries the enlightened spirit prepares for us. “When society has no color differentiation of pants, there is no purpose!” The best is the enemy of the good. an evening of work without a cooler to the load of about 100-150 W heating is not noticed in the future plans to put 2 automatic circuit at 25A to a 12 circuit and 2A to 220c, and cooler just in case I’m in the circuit 12v put a conventional fuse 30a (with cars) and after him a powerful diode – to protect against polarity reversal (inadvertently) _________________ Oh, how many wondrous discoveries the enlightened spirit prepares for us. “When society has no color differentiation of pants, there is no purpose!” The best is the enemy of the good. The diode is a good idea, you should also put a battery charge indicator, if only the output had a pure sine instead of approximation. About ten years ago I had a Back UPS 420 rebuilt and it lasted about ten years near batteries in an unheated shed. Then it got rusty and died:) Now I have a Chinese Porto 300W inverter with high frequency conversion and PIC microprocessor. I would have done some work with the firmware, to make it more usable, at least I rearranged the cutoff thresholds for my alkaline batteries. The IRF740 high voltage switches burned a few times, but it was possible to re-solder them to new ones. I had it on/off with a toggle switch from home. It was not difficult to figure out which wire to short circuit). In general, I wonder if for any similar inverter schematic is available on the Internet? I would be like this for experimentation and remake bought some interesting ideas, but completely from scratch soldering somehow do not want. I’ll raise an antique topic, because I could not find an answer to another question on the UPS (inponchek 08 year) have long been using 800VA version, but there is a problem – it is under load, very quickly goes into overdischarge protection of the battery using in the car – and the autopump discharge curve is sharper, and actually turns off at 70% of battery charge Hence the question – how to make the CPU of this UPS think that the voltage is normal – that is, he sucked the battery to zero (or up to 8V so as not to destroy completely), but then the default is 10.2V. ——— // aha, there is a trans is 280W – although in fact it should give 480W. so relayno on the load of 400-450W in the trans overheat fuse burns out. but 200-250W it can handle for a long time // checked 100-120W for 15-16 hours of continuous operation – everything tiptop. 10.2V is pretty much zero capacity. Or do you need to kill batteries quickly? Maybe you just need thicker wires for your load? If you measure it with the battery disconnected from the load, then yes. But if under load current, the voltage strongly depends on this current due to a rather noticeable internal resistance of the battery. The most obvious example – in a car, when the battery is fully charged and the starter is on, the voltage can be 9 volts, because the starter draws a lot of current. It is possible, if the starter “shakes” – the armature on the stator because of the wear of bushings. and in the norm it should not drop below 11.5 volts at a discharge current of 100. 120A. that’s how they test new ones with a loading fork: if it’s lower, they charge it, and you have to take another one to the customer. _________________ the human soul is dark and easily turns to evil Hello!

UPS is a very profitable device. As long as it works, the user has no problems with power supply. But this is not the end of the functionality of this device. The simplest modification of an uninterruptible power supply makes it possible to create on its basis such devices as a converter, power supply and charger. How to convert the UPS to a voltage converter 12/220 VA voltage converter (inverter) converts a constant 12-volt current into alternating current, while increasing the voltage to 220 volts. The average cost of such a device is $60-70. However, even owners of worn-out uninterruptible power supplies with battery start function have a very real chance to get a working converter for free. In order to do this you will need to do the following: Open the case of the UPS. Dismantle the battery by removing two wires from the drive terminals – red (for plus) and black (for minus). Dismantle the speaker – sound alarm device which looks like a centimeter washer. Solder a fuse to the red wire. Most designers advise using a 5 amp fuse. Connect the fuse to the “input” pin of the UPS, the socket where the cable that connects the UPS to the wall outlet was plugged in. Connect the black wire to the free contact of the “input” socket. Take the regular cable to connect the UPS to the socket, cut off the plug. Connect the plug to the input jack and identify the wire colors corresponding to the red and black pins. Connect the wire from the red contact to the battery plus and the wire from the black contact to the minus. Interior of the Eaton 5P 1150i UPS Only uninterruptible power supplies with a battery start function allow such a transformation. That is, the UPS must initially be able to turn on from the battery, without being plugged into an outlet. If the UPS has a standard socket – 220 volts can be taken from its contacts. If there is no such socket, it will be replaced by an extension cord connected to the “output” socket of the uninterruptible power supply. The plug of the extension cord is removed, and then the wires are soldered to the contacts of the “output” socket. The main disadvantages of such inverters :
How to turn an uninterruptible power supplyIn this case, from the whole construction of the UPS will need only a transformer. That’s why the user, who has decided to make such alteration of UPS, will have either to gut the whole UPS, leaving only the case and transformer, or to remove this part, having prepared a separate case for it. Then proceed as follows: Using an ohmmeter, determine the winding with the highest resistance.Typical colors are black and white. These wires will be the input to the power supply. If the transformer remains in the UPS, you can skip this step – the input to the homemade power supply in this case will be the “input” socket on the end of the UPS, which connects the device to the socket. Next, an AC current of 220 volts is applied to the transformer. After that, the voltage is removed from the remaining contacts, finding a pair with a potential difference of up to 15 volts. The typical colors are white and yellow. These wires will be the output from the power supply. The input to the power supply is formed from the wires on one side of the core. The output from the block is formed from the wires on the opposite side. At the output of the power supply put diode bridge. The consumers are connected to the contacts of the diode bridge. Transformer Typical voltage at the output of the transformer is up to 15 V, but it will subside after connecting to the homemade power supply load. Output voltage to the designer of such a device will have to pick up through experimentation. Therefore, the practice of using a UPS transformer as the basis of a power supply for the computer is not the best idea. Rebuilding an uninterruptible power supply for chargingIn this case, you do not need a minimal transformation similar to the one described in the paragraph above. After all, the UPS has its own battery, which is charged as needed. The bottom line is that to turn the UPS into a battery charger you need to do the following: Locate the transformer’s primary and secondary circuits. This process is described in the paragraph above. Put 220 volts into the primary circuit by plugging in a voltage regulator, a light bulb rheostat can be used as such to replace a traditional switch. The regulator will help calibrate the voltage on the output winding within the range of 0 to 14-15 volts. The location of the regulator is in front of the primary winding. Connect a 40-50 amp diode bridge to the transformer secondary. Connect the terminals of the diode bridge with the corresponding poles of the battery. The battery charge level is monitored by its indicator or a voltmeter. How to properly fill up a car air conditioner with your own hands? When
