DIN rail-mounted multi-phase power supplies: Key information

The 2-phase versions of the power supplies offer flexibility in power supply:

• they can be supplied with single-phase voltage (230VAC) using L and N wires and PE. In this case, the L wire is connected to the L1 terminal of the power supply and the N wire to L2;
• alternatively, they can be supplied with two-phase interphase voltage, using L1, L2 and PE or zero conductors, which increases their versatility and adaptability in different network configurations.

The 3-phase versions of the power supplies also offer a variety of power options:

• they can be powered from a three-phase mains using L1, L2, L3 and PE/zero wires;
• in addition, they can be powered by two-phase interphase voltage using L1, L2 and PE or zero conductors.

What's more, both 2-phase and 3-phase power supplies can be supplied with DC voltages of up to 780 VDC, making them suitable for use in rail transport.
