FAQ
What output currents are available?
The range offers three output current options: 1.5A (BF560-24/E), 3A (BF562-3/E), and 5A (BF562-5/E), all providing 24V DC output to suit different system requirements.
Can the PSU be customised for specific applications?
Yes, all models can be optionally customised using a BF423 configurator and PC. Configurable parameters include float voltage temperature compensation, battery charge rate, battery impedance settings, and input/output configurations.
What battery types and capacities are supported?
The PSUs support VRLA batteries with capacities ranging from 2Ah up to 17Ah (depending on model), with batteries charged to 80% capacity within 24 hours. The actual maximum battery size depends on the enclosure dimensions.
How does the battery fault monitoring work?
The PSUs monitor battery resistance to EN54-4/A2 requirements. The fault threshold relates directly to the battery’s ability to deliver rated current to the load, helping identify degraded batteries that may have increased internal resistance.
What certification standards do these PSUs meet?
All models include the same electronics as EN54-4/A2 certified PSUs and comply with EN50131-6 grades 1-4 for security applications. Full compliance with all relevant standards must be verified with the complete installation.
What data can be extracted from the PSU?
The bi-directional data port provides access to thermistor measurements, battery terminal voltage, system voltage at load terminals, battery charge current, load current, battery impedance, and ASCII text string status messages.
