B&K Precision 1687B 36V 10A Switching DC Power Supply

SKU CH-E69F-V06CW

A switching bench supply delivering 1 to 36 volts and up to 10 amps with automatic CV/CC crossover and three user presets

  • TypeElectronic
  • Adjustable 1-36 V output suits many test setups
  • Delivers up to 10 A for higher-current loads
  • Automatic CV/CC crossover protects the device under test
  • Three voltage and current presets speed up repetitive work
  • Analog remote control adjusts output without front-panel access

Compact bench power supply for lab and test work

The B&K Precision 1687B is a switching DC power supply designed for bench use in R&D, service, production testing and university labs. It delivers adjustable output from 1 to 36 V and 0 to 10 A in a lightweight, compact form factor. Automatic CV/CC crossover protects the unit and the device under test during operation.

Three user presets and analog remote control

Three user-defined voltage and current presets allow quick recall of common test configurations without re-entering values. The analog remote control function lets you adjust output power, voltage and current externally without touching the front panel. Dual-action coarse and fine rotary encoders make setting levels fast and precise.

10 A maximum output current

The supply provides up to 10 A across its 1-36 V range, which determines whether it can power a given load. Builders who need more current for high-power applications will need a different unit.

Questions about this item

How often will the internal fan on the 1687B need cleaning or replacement?

The unit uses forced-air cooling; keep the intake vents clear and clean dust from the fan periodically to maintain airflow.

What limit will I hit first when running the 1687B at full 10 A output continuously?

The 36 V / 10 A ratings define the maximum continuous output; sustained operation at the edge of both limits will trigger thermal protection before any electrical limit is exceeded.

How much heat and noise does the 1687B produce during all-day bench use?

As a compact switching supply it generates noticeable heat at high load; the internal fan runs whenever the chassis temperature rises, producing audible airflow noise.
