C-TEC 90-20 FM

Short Description

The C-TEC 90-20 FM series DC buffer module series uses ultracapacitors as energy storage. Under normal operation, these capacitors will be charged via an external charging unit like the UCCTEC. If the power supply is interrupted, the energy which is stored in the ultracapacitors is available to energize the load. The load will be supplied by the buffer module until the energy out of the capacitors is consumed. The buffer time depends on the charge state of the capacitors and the discharge current.

The buffer module has the following features:

·         Long-life maintenance-free caused by using ultracapacitors

·         Microprocessor controlled monitoring of the ultracapacitors

·         Condition monitoring via signals to the charging unit

·         Basic-balancing ensures energy saving
