Description
DRS-480 is a 480W AC/DC DIN rail type security power supply series. In addition to the primary output,
there is an additional charger circuit that will automatically adjust charge current depending on the
primary output current. DRS-480 accepts the universal input between 90VAC and 305VAC, and supports
output 24VDC, 36VDC, and 48VDC nominal systems. With high efficiency up to 93.5%, it can operate
with free air convection cooling under -30C through 70C ambient temperature. In addition to the key
protection features such as overload protection, over voltage protection, battery low voltage disconnect,
and battery reverse polarity protection, the DRS-480 also provides Form-C contacts and LED indicator
alarm signals for AC-fail, battery low, charger fail, and DC-OK to allow easy integration into security
systems that comply with local alarm codes.
