Newmar 115-12-20a Power Supply 115-12-20A Power Supply This super-rugged DC power supply is ideal for powering 12-volt communication and navigation equipment onboard commercial vessels where reliability is essential. The proven linear circuit design provides pure noise-free output and a long service life. Features: Excellent Regulation and Ripple Spec (output voltage maintained within 1% under all rated line and load conditions) Polyurethane conformal coated PC board and corrosion-resistant heavy-duty aluminum case with integral shock mounts assure survival in hostile environments The heat generated by semi-conductors is extracted and dissipated by large heat sink fins for cool operation Protection: overvoltage, current limit; (set @ 105% of intermittent rating), thermal overload, and input/output fusing Thermally activated cooling fan on “CD” units Specifications: Nominal Input/VAC: 115/230 Maximum Input Current @115: 5.5 Maximum Input Current @230: 2.5 Output Amperage (Intermittent): 20 Output Amperage (Continuous): 8 Weight: 20 lbs. / 9.1 kg Case Size: H x W x D (inch): 5.7” x 4.8” x 16.3” Input Range 105-125/210-250 VAC (selectable), 50-60 Hz; Derate to 50% output below 110 and 220 VAC Operating Temperature Standard Units – 0-50 degrees C, Derate linearly from 100% @ 40 degrees C to 50% @ 50 degrees C thermal shutdown @ 85 degrees C case temperature Duty Cycle: Intermittent: 20 minutes max on time, 20% duty Continuous: 24 hours/day 100% Duty Options: Modify for use as a battery charger The output voltage is adjusted (see Output Voltage for range) Transfer relay for back-up battery in event of power failure (ERC option) Output Voltage: 13.6 VDC (internally adjustable 12.6-14.5 VDC) Ripple: 40mV P-P (@ 110-125 / 220-250 VAC input) 1% Line and Load (@ 110-125 / 220-250 VAC input) Mechanical: Powder-coated aluminum heat sink case Front panel terminal block Heavy-duty mounting flange Conformal-coated PC board This product may not be returned to the original point of purchase.
