Phoenix Contact Quint Oring active power redundancy module

Click2Contact

The Quint Oring active redundancy module for an output current of 80 A is an addition to Phoenix Contact’s line that already includes 20 and 40 A models.

The modules provide information on the output voltages of the power supply units, defects in the wiring or decoupling section, and the present load current. Permanently monitoring the load current offers an important advantage when expanding or upgrading systems, because if additional loads are connected to a redundant power supply when expanding the plant or system, this can result in a loss of redundancy.

The ACB (auto current balancing) technology doubles the service life of the redundant power supplies, ensuring that both units work under the same load. The load current is automatically distributed in a balanced manner. The 1 x 20, 1 x 40 and 1 x 80 A modules are suitable for DC voltages of 18-30 V. The 32, 38 and 66 mm wide units are simply snapped into place on the mounting rail. Suitable for industrial environments, they operate at ambient temperatures from -25 to +70°C and carry continuous currents of 2 x 15, 2 x 26 or 2 x 45 A at ambient temperatures up to +40°C.

The Quint Oring redundancy module uses MOSFETs for decoupling instead of the usual Schottky or silicon diodes, therefore saving energy by up to 70%. Using two positive output terminals, the wiring can be redundantly routed to the loads.
