High Power Switching DC Power Supplies

Models 1900, 1901 & 1902

Full-Featured DC Power Supplies to
Meet Your High Power Needs

B&K Precision models 1900, 1901, and 1902
are laboratory grade switching DC power
supplies with high current output in a small,
lightweight form factor. The 1900 Series provide
various configurations of high output voltage or
high output current and feature rotary encoder
control knobs, which make setting voltage and
current fast and precise. Its dual action push
button allows the user to set both coarse and

its preset and remote control modes. Save up to
three different presets of voltage and current
values for quick recall. The analog remote
control function allows the output power,
voltage, and current to be adjusted without
touching the front panel of the power supply. A
remote sensing terminal (model 1900 only) is
also available to compensate for voltage drop
across load leads.

fine, voltage and current levels.

These features make the 1900, 1901, and 1902
In addition to constant voltage (CV) and
constant current (CC) modes, the high efficiency
DC power supply offers a unique solution with

suitable for a wide range of applications requiring

high current including production testing,

telecommunications, R&D, service, and

university labs.

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.

Remote Sense (Model 1900 only)

Improve regulation of the power supply’s
output voltage at the load by using the
remote sense terminals to compensate for
voltage drop across load leads.
