Kenwood PS20-18 User Manual

REGULATED DC POWER SUPPLIES
58
The PS Series power supplies are DC constant-voltage
(CV), constant-current (CC) power supplies based on
the variable switching method, featuring compact size,
light weight, excellent reliability and the variable
outputs. They have been designed as highly universal
stand-alone type models putting emphasis on the ease
of operation and safety and equipped with a variety of
protection functions. Three capacity types are
available including 360W, 720W, and 1080W and 13
kinds of variations are available by combining ranges of
0 to 6 V, 10 V, 20 V, 36 V and 60 V. Several versatile
applications are also provided including remote control
functions with GP-IB control capability (which is possible
when the optional GP-600 is used.)
Compact Size, Light Weight, High Efficiency
Thanks to the advanced switching method, the PS Series power
supplies are both compact and light , with less than half the mass
and volume of previous power supply models, resulting in an
excellent space factor and high efficiency
.Digital Display of Voltage and Current
Output voltage and current are indicated on 7-segment red LED
displays to allow easy checking.
