Power Supplies Heavy Duty Power Series
These super-rugged DC power supplies are ideal for powering 12 and 24 volt
communication/navigation equipment onboard commercial vessels where reliability
is essential. The proven linear circuit design provides pure noise free output
and 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 assures survival in hostile
environments
- 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
