60 V 5 A bench supply

The B&K Precision 1685B is a switching DC power supply that delivers up to 60 V and 5 A for a total of 300 W. It suits engineers, technicians and students who need a stable, adjustable source for prototype testing, circuit development or classroom demonstrations.

Replaces bulky linear units

The switching design reduces weight and heat compared with traditional linear supplies of similar output. The upgrade is worthwhile when bench space is limited, when fan noise must be kept low or when the wide 100-240 V AC input lets the unit move between regions without a voltage selector.

Fits a standard bench setup

Dual LED meters show voltage and current simultaneously while banana plug terminals accept common test leads. Constant-current operation protects the device under test, and built-in overload, over-temperature and over-voltage safeguards shut the output down before damage occurs. The supply needs only a mains socket and frees the user from external metering or current-limiting accessories.
