DC 12V 100A 1200W 電源 110V AC - 12V DCコンバーター

Its a good option for a more costly power supply. It has one flaw..the connection buss can be delicate and brake if miss handled. May want to reinforce!

SE-12-1200 model. The power supply output voltage is adjustable. I stopped increasing at 24V. I’m sure it goes beyond that. I have it hooked up to amplifiers I repair. I tested it out on a PPI A600 class A/B amp powering a Phoenix gold titanium elite 12D. I didn’t have a clamp to measure Amperage. It definitely puts out quite a bit of current. If it lasts, this is a great value. It will be great for burn in on amps I repair. I’m very impressed with the current output and price. I will wire a switch to turn it on and off so I don’t have to unplug it every time I use it. Would definitely recommend and buy again. I got

Runs great no clips or sparks at all if you know how to install but makes my sound system sounds great.

I bought this to use in conjunction with an inverter, so that I could change the frequency from 50hz (from mains) to 60Hz for a dishwasher (1000w). Hence it was required to provide continuous power during operation of the device. Also I only needed to use one output connection and not the three that came with. This was a little bit of a chore as the slots to screw in the wires could not accommodate higher gauge wires. I used the wire supplied with the inverter which i believe was 2AWG. This could not fit into the screw in terminals of this rectifier and I had to cut off some copper strands to make it work. While this felt unsettling it did work however. It worked for maybe 2 weeks to provide almost stable output in the region of 11.9 to 12.5 Volts. This allowed my setup to work an I was happy. After 2 weeks, I noticed some voltage fluctuations in the 10v to 14v range. The setup still worked, but the voltage fluctuations were noticeable. Then voltage fluctuations became more sporadic dropping to 5 and then the failsafe on my inverter kicking in to shut off power. I did a check with a thermal camera and noticed temperatures of 60 - 80 degrees Celsius. near the coils were the highest. I let it cool down for a few hours and checked the temperatures before starting which were room temperature. I turned on and within a minute temperatures shot up to to 60-80 degree range and voltage also dropped quickly. I concluded something may have burnt out on the inside. Maybe some 'varnish' or coating came off the transformers or insulation was lost or not properly applied so it was only a matter of time, and hence the rectifier heated up quickly and heat causes parts to be damaged and will reduce output power. In conclusion I think this may have been suitable for light weight use like for LED strings, or sub 30A DC output. On inspecting the inside components they did not appear well built for high current applications.

Ran 2 12 inch subs and 2 6x9s worked great for a cheap home automotive sound system make sure you wire it correctly runs nice cool
