DC-UPS pour condensateurs, primaire : 24 V, secondaire : 24 V, courant: 3, énergie: 1 kJ, dimensions: 92,5x60x116 mm, poids: 0.58 kg
Short description
The DC-UPS of the series C-TEC includes ultra-capacitors as energy storage inside the housing. This capacitor is charged with the system voltage (Ue) during normal operation. The connected loads are supplied as well from the system voltage. In case of an interruption of the system voltage the energy of the ultra-capacitors is released in a regulated way. With a dc dc converter, the load is supplied by the capacitor until it is discharged. The back-up time depends on the state of charge of the capacitors and on the discharge current.
