DRS-240 & DRS-480 DIN Rail Security Power Supplies

MEAN WELL DRS-240, and DRS-480 AC/DC DIN Rail-Type Security Power Supplies are 240W and 480W all-in-one intelligent security power supplies. In addition to the primary output, the MEAN WELL DRS-240 and DRS-480 AC/DC DIN Rail-Type Security Power Supplies feature an additional charger circuit that automatically adjusts the charge current depending on the primary output current. DRS-240 and DRS-480 accept a universal 90V_AC and 305V_AC input voltage. DRS-240 supports output 12V_DC, 24V_DC, 36VDC, and 48V_DC nominal systems, while DRS-480 supports 24V_DC, 36V_DC, and 48V_DC. With high efficiency of up to 93.5% (DRS-480) or 92% (DRS-240), these power supplies can operate with free air convection cooling under -30°C through +70°C ambient temperature. Key protection features include overload, over-voltage, battery low voltage disconnect, and battery reverse polarity protection. DRS-240 and DRS-480 also provide 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.
