CP-B range
Ultra capacitor based buffer modules
Power supply systems have to be highly reliable in most areas of energy management and automation technology. Often batteries are used for supporting the supply system in case of mains failures. Batteries have limited lifetimes depending on environmental parameters and have to be maintained regularly, which causes efforts and costs. Using the latest ultra-capacitor technology, ABB offers an innovative and completely maintenance free new product for buffering the 24 V DC supply in case of interrupted mains on the primary side of the switch mode power supply.
The CP-B range is an ultra-capacitor buffer energy storage for power supply units which ensures a short term uninterrupted power supply system. In case of a power loss, the energy stored in the capacitor guarantees that the load is continually provided up to several hundred seconds depending on the load current.

Characteristics

• 3 buffer modules for buffering 24 V DC:
• CP-B 24/3.0 (3 A / 1 kWs1))
• CP-B 24/10.0 (10 A / 10 kWs1))
• CP-B 24/20.0 (20 A / 8 kWs1))
• CP-B 24/3.0 and CP-B 24/20.0 expandable with
• additional extension module(s) CP-B EXT.2 (2 kWs1))
• LEDs for status indication
• Relay contacts for status messaging
• Very high backup times (e.g. with CP-B 24/10.0 up to 8 minutes at 1 A load current)
• Short charging times
• High efficiency, higher than 90%
• Wide temperature range
• DIN rail mountable, compact enclosures
• Advantages in comparison to battery buffers
• Maintenance free
• No deep discharge
• Temperature resistant

Electronic Protection Devices EPD24-TB-101
for use behind 24 V DC Switch Mode Power Supplies
The protection devices EPD24 extend the ABB product range of modular DIN rail components by electronic overcurrent protection modules for selective protection of 24V DC load circuits. This protection is achieved by a combination of active electronic current limitation in the case of a short circuit and an overload deactivation from 1.1 x In upwards. If a fault occurs in a load circuit, the protection device EPD24 will detect this rapidly and reliably, disable the power output transistor and hence interrupt the current flow in the defective circuit. The maximum possible overcurrent is always limited to 1.5…1.8 times the selected rated current. An activation of capacitive loads up to 20,000 μF is possible, deactivation only occurring in the case of overloads or short circuits. Selective deactivation of the defective current circuit means undefined error states and a complete system stop are prevented.

Features

• Selective load protection one, electronic trip characteristics.
• Active current limitation for safe connection of capacitive loads up to 20,000 μF and on overload/short
• circuit.
• Current ratings 0.5 A...12 A.
• Reliable overload disconnection with 1.1 x IN
• Manual ON/OFF button
• Clear status and failure indication through LED and auxiliary contact.
• Integral fail-safe element adjusted to current rating.
• Width per unit only 12.5 mm.
• Rail mounting
• Ease of wiring through busbar LINE+ and 0 V as well as signal bars.
• UL- and CSA-approvals allow international use of the devices.
