• Variable Output Voltage: 1 - 60 V
• Variable Output Current: 0 - 5 A
• Automatic CV/CC crossover operation
• Lightweight and compact
• 3 user-defined voltage and current presets

BK Precision 1685B series is a laboratory grade switching mode DC power supplies with high current output in a small form factor and lightweight package. It provides various configurations of output voltage and current, and make setting voltage and current levels fast and precise through its dual action, coarse/fine rotary encoder control knobs.

In addition to its constant voltage (CV) and constant current (CC) modes, the high efficiency DC power supply offers a unique solution with its preset and analog 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. These features make the 1685B Series suitable for a wide range of applications including production testing, telecommunications, R&D, service, and university labs.

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.

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.

Control your instrument through remote control PC software or use programming commands to communicate with your instrument.
