The RPS series
has the electric circuit protection function can stop the output and brings a
3.3V/5.0V/1A fixed output
Can work at the full load for a long time, can be used as a
regulated power supply or a stabilized current supply。
roduct Overview
RPS, RKS series adjustable dc regulated power supply is designed for
laboratory, school and the production line, the output voltage and load
current can be adjustable between 0 and the nominal value.
Stability and ripple coefficient is good can perfect
protection circuit.
RPS series is linear dc regulated power supply
RKS series is switch dc regulated power supply
