CP-B range
Benefits and advantages

Power supply systems have to be highly reliable in most areas of Characteristics
energy management and automation technology. – 3 buffer modules for buffering 24 V DC:
Often batteries are used for supporting the supply system in
case of mains failures. Batteries have limited lifetimes depending CP-B 24/3.0 (3 A / 1 kWs1))
on environmental parameters and have to be maintained regu- CP-B 24/10.0 (10 A / 10 kWs1))
larly, which causes efforts and costs. CP-B 24/20.0 (20 A / 8 kWs1))
– CP-B 24/3.0 and CP-B 24/20.0 expandable
3 Using the latest ultra-capacitor technology, ABB offers an in- with additional extension module(s) CP-B EXT.2
(2 kWs1))
novative and completely maintenance free new product for – LEDs for status indication
buffering the 24 V DC supply in case of interrupted mains on the – Relay contacts for status messaging
primary side of the switch mode power supply. – Very high backup times (e.g. with CP-B 24/10.0
up to 8 minutes at 1 A load current)
The CP-B range is an ultra-capacitor buffer energy storage for – Short charging times
power supply units which ensures a short term uninterrupted – High efficiency, higher than 90%
power supply system. In case of a power loss, the energy stored – Wide temperature range
in the capacitor guarantees that the load is continually provided – DIN rail mountable, compact housing
up to several hundred seconds depending on the load current.
Advantages in comparison to battery buffers:
– Maintenance free
– No deep discharge
– Temperature resistant

– A (UL508, CSA22.2 No 14), R approvals
