C-TEC 5 Series 24V 5A Encased Power Supply PCB Only (BF562-5/E)

The C-TEC BF562-5/E is an encased 24V 5A switch mode/digital hybrid power supply from C-TEC's 5 Series. It uses the same electronics as the LPCB/VdS certified BF562-5 EN54-4/A2 boxed PSU, but is supplied on a metal base plate with a plastic cover so it can be mounted inside a third-party (OEM) enclosure. 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 BF562-5 EN54-4/A2 boxed 24V 5A PSU
• Metal base plate for straightforward mounting inside third-party enclosures
• Plastic cover over the PCB guards against touching live parts (to VDE 0100-410)
• Single-pole volt-free changeover relay that switches on any fault condition
• Fault type and hazardous voltages present LEDs
• Two selectable battery charge currents
• Battery resistance monitoring to EN54-4/A2; fault impedance limits can be optimised to suit the load current
• Mains fail simulation mode
• On-board temperature sensor, with an optional BF322 remote battery temperature sensor
• Can be customised with a BF423 configurator and PC (float voltage temperature compensation, charge rate, battery impedance, input/output settings)
• Bi-directional data port for PSU status data
• Electronic functions comply with EN50131-6 grades 1-4 for security applications
• On-board PSU status LED flash codes for mains failure, low or critical battery voltage, charger failure, charger OK, no batteries fitted, battery resistance fault and output over voltage
