AKKUTEC DC-UPS Buffer Unit (without batteries)

The battery buffered DC power supply works in stand-by parallel mode and, in connection with a lead-acid battery, ensures a safe continuous DC power supply during a determined time interval in case of main power failure. The total output current is shared between supply of the loads and charging of the buffer unit.

C-TEC Ultra Capacitor Module

The DC-buffer module of the series C-TEC works with ultra-capacitors as energy storage inside the housing. These capacitors are charged by an external regulated DC-power supply in normal operation. In case of an interruption in the DC-power supply, the energy of the capacitors is released. The load is supplied by the buffer module until it is discharged. The back-up time depends on the state of charge of the capacitors and on the discharge current.

Environmentally safe No toxic chemicals
Virtually maintenance free Lasts up to 15 years
Operating temperature range -40°C to +65°C Higher energy vs. electrolytic capacitors
Higher power vs. batteries Resists shock and vibration

Traditional lead-acid batteries rely on aging technology and toxic chemicals for energy storage. While adequate for many applications, they have limitations for emerging applications that require safe, dependable, quick back up power, over long periods of time. Ultra capacitors in DC-UPS applications ensure that critical information and functions are available when supply voltage dips, sags, drops out or surges, or during a battery changeover. Working in conjunction with a complementary power supply, ultra capacitor modules reliably supply energy in peak power demand conditions and short power outages. They reduce stress on the primary power supply and extend its usable life.
