3 Phase Power Supply Modules
High-efficiency 3-phase DIN rail power supplies engineered for demanding industrial environments, from control cabinets to semiconductor manufacturing and renewable energy applications.
WHY 3-PHASE??
Most industrial facilities run on 3-phase power, and the POWER 3AC series is built to take advantage of that directly. Compared to single-phase power supplies, 3-phase input draws less current per wire, produces smoother DC output, and requires no neutral connection. The result is simpler wiring, less heat, and a more stable power supply for your machines and control systems.
Key features of our 3-Phase Power Supplies:
-
High efficiency with ultra-slim DIN rail form factor
-
Wide input range 320 ... 600 (575) VAC / 450 ... 850 VDC, global three-phase grid compatibility
-
Power Boost 150 % for 7 s, handles high inrush and transient loads
-
Parallel operation up to 4 units, up to 960 W combined output with active current sharing
-
Adjustable output voltage via potentiometer, 24-28 V / 48-56 V
-
Full protection: over-voltage, over-current, short-circuit, over-temperature with auto-recovery
-
Built-in DC OK relay contact for system diagnostics and monitoring
-
Operating range -30 to +70 °C (start-up at -40 °C), conformal coating standard
-
20 ms hold-up time ensures stable DC power during mains fluctuations
