Access Control Power Supplies


The HP400ULACM4 is a 12VDC power supply that includes a HPACM4 access power controller to be used with card access systems. It provides 12/24VDC through four(4) or independently controlled, power-limited PTC protected outputs. It accept inputs from open collector sink or normally open (NO) dry contacts from UL listed security devices such as keypads, card readers, access control systems, PIR’s and push button delays. Outputs from the HPACM4 can switch power on or off at 12 or 24VDC. Each output can be configured to respond to FACP input. The outputs can also be individually selected as isolated dry contacts (Form “C” configuration). The HPACM4 can be configured for common power, which means the same supply drives both output power and control board power, or alternatively, dual power input, which separates control board power and output power.
