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 supportsoutput 24VDC,36VDC, and 48VDC nominal systems. With high efficiency up to 93.5%, it can operatewith free air convection cooling under -30 ℃ through 70℃C ambient temperature. In addition to the keyprotection 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 indicatoralarm signals for AC-fail, battery low, charger fail, and DC-OK to allow easy integration into securitysystems that comply with local alarm codes.
