The C-TEC BF562-3/E is an encased 24V 3A switch mode/digital hybrid power supply board from C-TEC's 5 Series range, supplied without an enclosure. It has the same electronics as C-TEC's LPCB/VdS certified EN54-4/A2 boxed BF562-3 PSU, and its metal base plate makes it easy to mount inside third-party OEM enclosures. Full compliance with the relevant standards must be checked by the responsible person once the PSU is installed in a suitable enclosure.
Key features
- Same electronics as the EN54-4/A2 certified BF562-3 boxed PSU
- Plastic cover over the PCB guards against touching live parts
- Metal (Zintec) base plate for mounting in OEM enclosures
- Single-pole volt-free changeover relay that switches on any fault condition
- Two selectable battery charge currents
- Battery impedance monitoring to EN54-4/A2, with fault limits that can be optimised to suit the load current
- Mains fail simulation mode
- On-board temperature sensor, with an optional remote thermistor
- Status LED flash codes for mains failure, low or critical battery voltage, charger status, no batteries, battery resistance fault and output over-voltage
- Can be customised with a BF423 configurator and PC
- Electronic functions comply with EN50131-6 grades 1-4 for security applications
