The DC-buffer module C-TEC works with Ultra-capacitors as energy storage inside the housing. In case of an interruption of the DC-supply, the energy of the Ultracapacitors is released. The load is energised from the buffer module, til it is discharged. The back-up time depends on the state of charge of the capacitors and on the discharge current.

• compact design, assembled in one housing
• maintenance-free
• deep discharge protection, thus unlimited storage possible
• no gas emission, so the use in closed housings is possible 
• fast availability because of short recharge time after discharge

Compared with normally used buffer modules with capacitors, with the C-TEC higher back-up times can be obtained. They depend on the energy of the capacitors and can be calculated as follows:

Back-up time  =  energy
                         voltage x current

with fully charged capacitors:

                    10000 Joule     = 50 secondes
                    24V x 10A
