With the introduction of the C-TEC 2440 P the C-TEC series is increased up to 40A. The nominal input voltage amounts to 24 V +/- 10 %, the output voltage lies between 25.5 and 19 V, depending on the load and the state of charge. The unit provides a nominal output current of 40 A, but a short-time peak current of 90 A is possible. If voltage drops occur, the power supply is able to supply a load with 40 A for 4 seconds. An increase of the back-up time up to 20 seconds is possible with external C-extension modules. Ultra-capacitors are used for the buffering. Therefor the C-TEC 2440 P is as well as the other devices of the C-TEC-series maintenance-free and can be operated in a temperature range from -40 up to 60°C (storage temperature -40° up to +60°C).
