Designed to Make Your
Work Easier
Fully Protected
Have peace of mind knowing that these power
supplies come with built-in OVP (overvoltage
protection), OTP (overtemperature protection),
and OLP (overload protection) circuitry. These
protections help prevent serious damage to
equipment in case of power supply failure.
Custom Presets
Quickly use common voltage and current settings
with a flip of the Recall preset switch. Up to three
different presets can be set and recalled.
Analog Remote Control Capability
Use the included connector to wire up to an
external variable DC voltage source or variable
resistor to remotely control the power supply’s
output voltage and current or to turn the
output on/off.
PC Connectivity
Control your instrument through remote
control PC software or use programming
commands to communicate with your
instrument.
