There was a problem filtering reviews right now. Please try again later.
They contacted me and offered support to make sure nothing could be done to get it working. Then they sent a replacement of the power supply!
Great quality power supply that had a problem and the company that makes it took care of the problem immediately and got me back to working!
Top quality product, service and support!
Will buy from again!
----------------------------------------------------------------------
The power supply was easy to use and provided a stable power source.
The meter for the output was slightly off +/- .2 (totally acceptable variance for a power supply of this level)
But that was the good.
The bad is that it just stopped working! I went to turn it on and pressed the power button, nothing. I checked the power cord, the outlet and the fuse. Still nothing.
For the price it should have lasted a lot longer than 8 months!
Don't try to run it continuously at 300 watts, though!
I like that encoders because I hate the separate coarse/fine pots on most power supplies. You can change the encoder step size so you don't need a separate control. Something I don't like is the three second delay between adjusting an encoder and transferring the reading to the actual setpoint. I understand why they did this but it means you cannot gradually adjust the output voltage or current.
The leads that come with it are cheap to the point of being useless. They use fork terminals instead of banana plugs. The alligator clips are beyond cheap and the jaws don't stay parallel. The worst part is that the boots are so slick that it is very difficult to squeeze the clips to open the jaws.
According to my Fluke 179, the voltage and current calibration errors are both a fraction of 1%
It has been a few days since my original review and as of this morning, the power supply won't go above 25 point something volts. I can dial the setpoint up to 31 but the actual output is only 25 and change. Too bad. I liked it before this happened. Amazon cheerfully sent me a new power supply.
