DC-DC CONVERTERS STANDARD & ISOLATED SERIES
Standard Series
Convert 20-50 VDC input to 12 or 24 VDC negative ground output for powering communication/ navigation equipment, on negative ground systems. (See Isolated series, page 22, for positive ground applications.) Ideal for powering voice, data and navigation electronics in marine applications.
- Excellent Regulation: Output voltage maintained within 1% under all line and load conditions within rating.
- Heat generated by semi-conductors is extracted and dissipated by large heat sink fins that maximize air contact for cool operation and long life of components.
- Polyurethane conformal coating on PC boards and corrosion-resistant anodized aluminum case with heavy duty shock mounts assure survival in hostile environments.
- Numerous converter and load protection circuits:
- Current limiting
- Automatic thermal shutdown
- Short circuit proof
- Reverse polarity
- Overvoltage protection
- Carries CE mark
Isolated Series
The Isolated series provides voltage conversion as well as input/output isolation, allowing use of negative ground gear to positive or floating ground battery systems, or vice versa. Many models may also be used as 12 or 24 volt stabilizers for highly input voltage sensitive equipment.
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 devices communication, navigation systems, and DC micro-processor based devices.
- 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 re-setting thermal shutdown
- High/low input voltage shutdown
- Polyurethane conformal coating on PC board
- Power “ON” light
- Rugged case designed for high vibration applications
