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
