Ultra capacitor based buffer modules

CP-B range

4

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.

Application example

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 min-

utes 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

• A approval (UL508, CSA22.2 No 14)

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 I

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 I

• 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.
