This new generation of SDC- 5200 series of voltage reducers offer regulated
13.8 V DC power from 20-30VDC source such as Land Rovers, commercial
vehicles, recreation vehicles, farming equipment and other diesel power
vehicles.
The very compact, lightweight and no vent hole casing construction is
possible because of the highly efficient, switch mode design with surface
mount devices.
Low heat output and low standby current take out the need for an external
power on-off switch.
The plastic clip-on mounting system makes the installation easy even in
awkward to reach spot. The unit is tamper and dust proof because of no vent
holes and no external fuse construction. The PCB component layout is
designed and built for vibration loosening resistant, and with moisture proof
coating making it ideal for off-road and harsh environments.
The advanced switching mode circuit design results a cool, silent, no
humming and no high frequency noise operation. Electronic safeguards and
fail-safe feature such as OVP ensure good protection to expensive connected
equipments even when there is a fault in the unit.
The 13.8VDC output can be used as a source for float charge for 12V auxiliary
battery.
Typical applications for this new generation of DC-DC converters are:
Radio communications, car entertainment such as DVD player, printers, on
board computers, security system, GPS, auxiliary lights, spot lights, charging
of 12V auxiliary battery, and etc.
• Slim, compact and light construction due to high efficiency & low heat
output.
• Dust and tamper proof due to extruded aluminum casing of no vent hole
& no external fuse.
• Reliable clip-on mounting bracket construction for easy installation even
in hard to get to spot.
• Vibration loosening resistant & coated PCB assembly, ideal for off road
vehicles environment.
• Advanced switching mode design & SMT components for high efficiency
& cool operation.
• Low standby current takes out the need for an external on-off switch.
• Over Voltage Protection against excessive output voltage in case of
wrong installation or fault.
• Auto-reset loss of earth protection.
• Auto-reset over power protection.
• Auto-reset reverse polarity protection.
• Separate LED indicator for operation and fault status.
• Meet e-Mark and CE standards.
