This is the new 2016 revision of the
Gopher CPS-3205C. Gopher has addressed some of the issues I found in the
old revision and sent me their latest for review. You will see a tear down as well as various tests performed on this power supply.
Top performance cost ratio. High power density, smallest and compact.
Aluminum shell, lower EMI

Power Supply Wanptek KPS305D
KPS series is a single set of
output, high precision double display switch dc power supply. Machines have
complete operating protection function, with high performance,
low ripple, high stability , light
weight and small volume etc. Current limiting protection can make RKS power
supply and load against accidental damage.
Features:
1. Have complete operating
protection function
2. Highly efficient, low ripple,
small volume, light weight
3. Double display voltage, current,
and high precision
4. Voltage stabilization, current
limiting, simple operation
5. Dual voltage input and convenient
choice
6. Temperature control fan heat
dissipation, low noise
7. Double potentiometer more precise
adjustment
