DRS - The new power supplies series

DRS-240 and DRS-480 are a 240W/480W AC/DC 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-240 and DRS-480 accepts the universal input between 90VAC and 305VAC, and supports output 12 VDC , 24VDC, 36VDC, and 48VDC nominal systems. With high efficiency it can operate with free air convention cooling under -30 degrees through 70 degrees ambient temperaturę. 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-240 and DRS-480 also provides Form-C contacts and LED indicator alarm signals for AC-fail, battery low, charger Circuit fail, and DC-OK to allow easy integration into security systems that comply with local alarm codes.
