Lifesafety Power FPO75-C4D8E1PDK 75W Power Supply 4-Relay Lock Control
Overview
The Lifesafety Power FPO75-C4D8E1PDK is a 75W regulated power supply purpose-built for access control and lock management in mid-scale security deployments. It delivers either 6A at 12V or 3A at 24V output — your choice depends on the total current draw of your door locks and auxiliary devices. This model includes four dedicated relay outputs for lock control plus eight additional DC auxiliary outputs, letting you distribute power and control signals to multiple devices from a single, fused supply. Each output is independently fused at 3A, so a short on one lock doesn't cascade across your entire access control system.
Compatibility
Designed for use with FAI (Failsafe/Failsecure Interface) systems and compatible access control panels that accept 12V or 24V regulated DC inputs. The four relay outputs are each selectable for failsafe, failsecure, or FAI-type operation, giving you the flexibility to mix lock types and control behaviors across a single panel installation. The eight DC auxiliary outputs can be assigned to either Bus1 or Bus2, supporting modular wiring in larger layouts. Verify your specific access control panel documentation for voltage and relay contact-type compatibility before ordering.
Installation Notes
Mount in a secure electrical enclosure away from moisture and direct weather exposure. Each of the four relay outputs and eight DC auxiliary outputs is fused independently at 3A per output — this means you can safely pull up to 3A from any single output without risking the others. Calculate your total load before choosing 12V or 24V: if your door locks and sensors draw more than 6A at 12V (or 3A at 24V), step up to a higher-capacity unit or distribute the load across multiple supplies. Standard DIN-rail or wall mounting is recommended; consult the unit's installation manual for exact terminal specifications and torque settings.
