PS0.EL 24Vdc Power Supply | Relcross Door Controls

24Vdc Power Supply

This continuously rated power supply accommodates Von Duprin EL devices on access control systems. EL devices are always free from fixings from the escape side. The PS0.EL power supply provides 24Vdc (unregulated) @ 16.0 Amps for 300ms. A regulated circuit charges the batteries (if fitted) at a float voltage of 27.6Vdc. Always use batteries with Von Duprin EL surface vertical rod devices.

All power supplies, when used with access controllers, switch power at the electrified lock when an authorised code, card, tag or fob is presented at the secure side of the door. Fail secure (FSE) locks require power to be switched on to release the lock. Fail-safe (FS) locks require that power is switched off. Both functions are provided via an Entry Relay. Relcross will provide the correct entry relay to suit the access controller. However, if we are not providing the controller, we must know the controller's output at the outset.

Relcross manufactures the PS0 series of power supplies and transformers specifically for use with access control and door control hardware. However, our power supplies can be used with any manufacturer’s electrified locks and accessories as long as the rating and operational expectations are checked carefully.
