12-12-35I DC ConverterThis isolated series provides voltage conversion as well as input/output isolation, allowing the use of negative ground gear in positive or floating ground battery systems, or vice versa. Using an isolated converter as a voltage stabilizer on 12- or 24-volt systems can solve conducted noise and interference problems on sensitive DC-powered communication, navigation systems, and DC microprocessor-based devices.Features: Wide range of input voltage Precise output voltage regulation Reverse polarity Input fuse/output fuse Total input/output isolation, pos. or neg. ground Current-limiting, short-circuit-proof output Automatic resetting of the thermal shutdown High/low input voltage shutdown Polyurethane conformal coating on PC board Power ON light Rugged case designed for high-vibration applications Specifications: Input Voltage: 10-16 Max Input Amps: 56 Output Voltage: 13.6 Output Amps (Intermittent): 35 Output Amps (Continuous): 20 Case Size (H x W x D): 6 x 6.8 x 16.5 inches (15.2 x 17.3 x 41.9 centimeters) Weight: 12 lb.
