Woehrle DC-virtalähde POWER-TEC 2420 kolmivaiheinen virtalähde lähtö 24V

Industrial control cabinets and automation systems often demand a reliable 24V DC bus that can handle heavy loads without flinching. The Woehrle POWER-TEC 2420 steps into that role, converting a three-phase 400V AC input into a tightly regulated 24V DC output with 20A capacity. Its rugged metal housing and DIN rail mounting make it a natural fit for machine builders and panel shops who need consistent power for PLCs, sensors, and actuators.

Key specifications

• Three-phase input: 3x 400V AC (±10%), 50/60Hz
• Output: 24V DC, 20A maximum, 480W total power
• High efficiency: >88% for reduced heat and energy costs
• Low ripple & noise: <50mVpp for clean DC supply
• Comprehensive protection: overload, short circuit, overvoltage, overtemperature
• Forced air cooling with integrated fan for continuous operation
• LED status indicators for Power OK and overload conditions
• Screw terminal connections for secure wiring
• DIN rail or chassis mount for flexible installation
• Safety certified: EN 61010-1, EN 61204-3

Why choose it

This power supply is built for demanding industrial environments where uptime is critical. The three-phase design balances load across phases, reducing current per phase and allowing smaller wiring compared to single-phase units at the same power level. The wide operating temperature range from -10°C to +50°C ensures reliable performance even in challenging conditions, while the fan cooling keeps components within safe limits during extended full-load operation. With its robust protection features, you can trust it to safeguard both itself and the connected equipment.

Ideal use cases

• Powering 24V DC control circuits in industrial machinery
• Supplying sensors, relays, and solenoid valves in automation panels
• Providing stable DC power for motor drives and servo controllers
• Backbone power for distributed I/O systems and fieldbus modules
• Replacing older linear supplies to improve efficiency and reduce heat

Good to know

The POWER-TEC 2420 is a regulated switch-mode power supply, meaning it maintains a constant output voltage despite fluctuations in the input or load. The screw terminals accept a range of wire sizes, making installation straightforward for qualified electricians. While it includes a fan, the unit is designed to operate quietly and reliably over its lifespan. Always ensure proper ventilation around the unit and follow local electrical codes during installation.
