Utilizing a standard 115Vac outlet as the power source, the bench top units are designed to provide variable voltage outputs of 1Vdc to 15Vdc, and up to 28A (at 13.8V) at continuous operation.According to BK Precision, the model 1689 regulated dc power supply features a front-panel mounted precision analog voltmeter and an analog ammeter, while model 1690 utilizes digital LEDs. Other front panel indicators and controls include an off/on power switch, a power LED, overload indicator light, voltage adjustment knob, and two pairs of snap-in output terminals.Both units are designed to provide variable output voltage of 1Vdc to 15Vdc, 28A (at 13.8V) output current, 5mV (peak to peak) ripple and noise, 5mV (+/-2 percent load) line regulation, 50mV (0-100 percent load) load regulation, and utilize a standard 120V/60Hz power source. Each unit measures 9.84" x 5.5" x 8.86", weighs 19.9 pounds and features overload protection, high radio frequency interference (RFI) stability, variable speed cooling fan, and multiple dc output terminals. Both models also offer multiple dc input terminals; two pairs of 3A, snap-in dc connectors on the front panel and a pair of 28A screw-on dc output terminals on the rear panel.The model 1689 will be priced at $275 each and the model 1690 at $349 and both are currently available.
