MeanWell DRS-240 240W All-in-One Intelligent Security Power Supply, 24V 7.7A, Grey, DIN Rail

DRS-240 is a 240W 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 theprimary output current.DRS-240 accepts the universal input between 90VAC and 305VAC, and supportsoutput 12VDC,24VDC,36VDC, and 48VDC nominal systems. With high efficiency up to 92%，it canoperate with free air convection cooling under -30℃C through 70Cambient temperature. In addition to thekey protection features such as overload protection，over voltage protection, battery low voltagedisconnect,and battery reverse polarity protection, the DRS-240 also provides Form-C contacts andLED indicator alarm signals for AC-fail, battery low,charger circuit fail，and DC-OK to allow easyintegration into security systems that comply with local alarm codes.
