The BK Precision Model 1670A is a general-purpose triple output DC power supply. Its main output is versatile constant voltage or constant current regulated power source that is variable from 0 to 30 volts and 0 to 3 amps. An indicator lights in the constant current mode, and serves as an overload indicator in the constant voltage mode.

While this model is competitively priced with most single-output power supplies, they have the added advantage of fixed 5 volts and 12-volt outputs capable of providing up to 0.5 amps each. One common application for this power supply is the powering of circuit boards while troubleshooting. Many circuit boards require two or three input voltages, with the most common values being 5 volts and 12 volts. These power supplies can provide up to three outputs simultaneously. Since each output is fully isolated, any output can be connected for positive or negative polarity.
