REES52 Voltage Boost Converter, DC 8-60V to 10-120V 15A Numerical Control Step Up Voltage Current Adjustable Regulator Constant Module Output 48V 24V 12V Power Supply with LED Display Heat Sink

Everything Executed properly Perfectly great quality Product working Excellent thanks. If you have same product in 25 Amps I'll again perches it so once again thank.

Great boost converter for diy hobbist. The day of purchase i tested the product the fan did run and went off. Guessing at load time of power mosfet the fan will work else will be turned off to save power. I tired with a 12v 7.2Ah battery @ c10. Was testing a fan of 48vdc with 0.21amp current. While connected to battery I got 12v at input terminal of the converter also got 12v at output side of the converter. Then I set my required voltage at the output ends and the fan works. Must need to have a multimeter because can't rely on voltage output or being showed in display. Though pretty accurate, but still though need to have multimeter because the amplifier is accurate in its output but while measuring with no load will get extra output voltage. Assume the output voltage set to 48v output terminal will show 49-50v. Though very easy to master those switch. The main purpose to write the review is that for new buyers who are willing to buy or pretty interested to buy sooner to let you know. If you provide 900watt in input then only expect 900watt in output. Don't expect you have a power supply of 400watt like i do a computer atx smps supply will boost output power to 900watt not possible after all. Voltage * current = wattage Assume if you have 12volt smps supply with at least 75amp(not just 7.5ah or 75ah battery) in input then only will you get 900watt in output Don't expect 15 amp with 120v at output with 900watt input but do expect 120v but 7.5amp at output when provided with exactly 900watt input. For a battery of 12 v the current capacity written in ah not amp. If you could know the discharge time of the battery probably it is c10 or c20 If 10 then for a 7.2ah battery 7.2/10=0.720A If 20 then for a 7.2ah battery 7.2/20=0.360A So if you have the exact watt fixed smps then you will surely get the same watt at output. I have a atx as mentioned before its 12v 21amp so will get exact 252watt in output.

I'm using it to boost up from 15 VDC to 120 VDC and it is working at a mere 65% efficiency, very much lower than the 85% mentioned in the specifications.

Product received as shown in the image . the item is well packed the working performance will be decided after 2 months of working

It's mentioned 15Amp 900Watt out put. But its having 60 watt with 0.5Amp capacity only.

not working after 1 month

Nice module.

Works well and as expected. The heatsink is sufficient enough fornmost cases. Although you might want to looks the uploading an open-source firmware.
