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
