240W All-In-One Intelligent Security Power

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 the primary output current. DRS-240 accepts the universal input between 90VAC and 305VAC, and supports output 12VDC, 24VDC, 36VDC, and 48VDC nominal systems. With high efficiency up to 92%, it can operate with free air convection cooling under -30℃ through 70℃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-240 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.
