Bringing in power where it's needed most
The Newmar Heavy Duty Power Supply is ideal for powering 12 or 12 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.
Newmar Heavy Duty Power Supply Features:
- Designed for powering 12 and 24 VDC communication/navigation
equipment aboard commercial vessels
- Input voltage 115 or 230 VAC selected by slide switch on the
front panel
- 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 aluminium 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
- Supply and Load Circuit Protection: overvoltage, current limit;
(set @ 105% of intermittent rating), thermal overload and
input/output fusing.
- Thermally activated cooling fan on "CD" units
