LifeSafety Power FPO75 75 W 4-Relay Lock Power Supply Board

Provide 75 W of power for low-voltage access-control locking circuits using a board-level assembly with four relay lock connections. Output capability is rated at 6 A when operating at 12 V or 3 A when operating at 24 V. These ratings allow the board to be matched to the voltage used by the connected locking hardware and the expected circuit load. Four relay lock connections give the board a defined role where lock circuits require relay-based connection points alongside their power source. It fits access-control panels and enclosure assemblies that need to support several locking circuits without treating the power board as a general-purpose network or computing component. Verify the intended lock voltage and calculate the connected load against the applicable current rating before installation. FPO75-C4D8E2M identifies the 75 W LifeSafety Power board configuration with the stated 12 V and 24 V output ratings and four relay lock connections. Its defining combination is a 75 W power rating paired with lock-relay connectivity, rather than power capacity alone. Use the complete ordering code when matching the required board configuration; FPO75 is the shorter model designation used in product searches and technical references.
