Sigma Instruments 5 Ampere 0-30Vdc Dc Regulated Power Supply

Bought this to support indian brand.No regulated output you set the volate and then connect the load the voltage drops immediately. What is the point of the regulated power supply that can provide a fixed volate.Very noisy fan. Very unhappy with the power supply.

I'm reviewing it after almost a year when it's no more working properly, so it produces smoke when cranked at 5amps.Pros. Good power supply for medium grade use not for prolonged use, if you're using it for 1-2 hours at once, it's fine then. I've mostly used it for charging up batteries.

Good product. Heavy duty, can take full 5 amp current. Working good for the past 6 months. I had some technical issue which was sorted out on the phone only. Will order 2 more
