Redundancy modules are installed in electrical panels to ensure the reliability of DC power supply to electrical devices.
- Electrical: 2 inputs 0-20A and 1 output 0-20A. Max current 30A for 5s.
Input and output voltages: 24VDC or 48VDC depending on the model.
- Output contacts: 2 independent contacts allow signaling the failure of the associated power sources.
- Physical: Metal housing, DIN rail mountable, 2-module width.
Connection via screw terminals.
- Reliability of power supply: Powered by 2 stabilized power supplies, the redundancy module allows doubling the power source of a device. In case of failure of one supply, the downstream device remains powered by the second supply. An output contact assigned to each input warns in case of a source failure.
- Compliance: CE, RoHs, Reach.
- Applicable standards: BS EN/EN55032 Class B
BS EN/EN 55035, BS EN/EN61000-4-2, 3, 4, 5, 6, 8, BS EN/EN55024
