Key Features; A powerful switch mode/digital hybrid PSU that can be customised to suit your exact requirements. Plastic cover on PSU PCB guards against touching live parts (to VDE 0100-410). Includes the same electronics as our BF560-24 LPCB certified EN54-4/A2 boxed 24V 1.5A PSU. Metal base plate facilitates straightforward mounting inside third-party OEM enclosures. Includes a single-pole volt-free changeover relay that switches for any fault condition. Includes a fault type & hazardous voltages present LED. Two selectable battery charge currents. Battery fault impedance limits can be optimised to suit load current (helps extend battery life). Mains fail simulation mode. Improved on-board temperature sensor with optional remote sensor. Electronic functions comply with EN50131-6 grades 1-4 for security applications. Optional PCB-only version (without a metal base plate) available.

C-Tec 24v 1.5A EN54-4/A2 Boxed Power Supply Unit (VDS Certified); BF362-1; Low current consumption Deep discharge battery protection and EN54 compliant reporting of battery impedance faults Single-pole volt-free changeover relay that switches for any fault condition Three LED indicators - supply present, general fault and auxiliary fault (for optional connection to third-party equipment) Link selectable battery charging capacity Environmentally-friendly charging circuit - dissipates just 0.35W compared to the industry norm of around 2.55W. Optional high-temperature output activates when internal box temperature reaches 55oC, for connection to ventilation fans, etc. Optional handheld status reader (shows internal temperature, charging voltage and current of connected PSU). Serial data link also provided for third-party OEM equipment All boxed versions third-party certified to EN54-4 (1997/A2:2006) by the VdS or LPCB
