Industrial multi-phase power supplies – reliable power for demanding applications
2-phase power supplies – flexible AC and DC power supply
Two-phase industrial switching power supplies offer a high degree of flexibility in power supply configuration:
- 230 VAC single-phase power supply – the power supply unit can be connected to a standard single-phase mains supply using the L and N wires and the PE protective earth wire. The live wire (L) is connected to terminal L1, whilst the neutral wire (N) is connected to terminal L2. This solution is suitable wherever only a single-phase mains supply is available.
- Power supply via phase-to-phase voltage from two phases - Alternatively, the 2-phase power supply unit can be supplied with phase-to-phase voltage (approx. 400 VAC) using the L1, L2 and PE wires or the neutral N wire. This configuration increases energy efficiency and flexibility of adaptation in various network configurations.
3-phase power supplies – three-phase power supply for high-power applications
Three-phase industrial power supplies for control cabinets support an even wider range of mains configurations:
- Three-phase mains supply – standard connection to a three-phase mains supply using the L1, L2 and L3 phases and the PE or neutral conductor. The ideal solution for powering industrial equipment with high power consumption.
- Two-phase supply – a three-phase power supply unit can also be powered from two phases using the L1, L2 and PE or N conductors, which offers additional flexibility when designing electrical installations.
DC power supply – applications in rail transport
Both 2-phase and 3-phase power supplies can be powered by a DC voltage of up to 780 VDC. As a result, multi-phase DC power supplies are widely used in rail transport, electric traction and UPS systems integrated with DC busbars.
Why choose multi-phase industrial power supplies for DIN rails?
When choosing multi-phase DIN rail power supplies for your installation, you benefit from:
- high energy efficiency – modern industrial-grade switching power supplies have an efficiency of over 90%,
- reliability and long service life – metal casings made from perforated sheet metal and industrial-grade components guarantee trouble-free operation for many years,
- power supply flexibility – compatible with single-phase, two-phase and three-phase mains supplies, as well as DC voltage,
- ease of installation – quick mounting on a 35 mm DIN rail in control cabinets and electrical switchboards,
- Wide range of applications – industrial automation, production lines, rail transport, BMS and HVAC systems, and many others.
If you are looking for a proven multi-phase industrial power supply that can meet the demands of your automation system or electrical installation, our multi-phase DIN rail power supplies are the solution that will meet the highest technical and reliability standards.
