PS Series Linear DC Power Supply
Introduction PS Series are high precision, high stability , high reliability and low ripple linear DC regulated power supply. The output voltage and output current between 0 to rated value is continuously adjustable . Constant voltage and constant current can automatic conversion . The power supply of this series is divided into two types . One has the function of conversion between mA and A in display output current (e. g . PS-202D) . The other has 4 digit LED display output voltage and output current , voltage display resolution is 10mV and current display resolution is 1mA(e. g. PS-2002D ) .
Features
a. Single channel output
b. Internal radiator and electronic temperature control cooling
c. 110V or 220V input voltage conversion select
d. Output current mA/ A conversion display ( e. g. PS-202D)
f. 4 digit LED display output voltage and output current ( e. g. PS-2002D)
g. Current-limiting protection and users can set the current-limiting protection point arbitrarily
h. Reverse polarity protection
