Wide auto-ranging input voltage for global compatibility. Built-in short-circuit and overload protection. LED status indicators for output voltage and fault. High hold-up time bridges brief power interruptions. Convection cooled for silent operation.
Application Scenarios
It supplies power for S7-400 PLC chassis, process control cabinets, manufacturing automation systems and industrial control panels.
Performance Parameters
Output regulation: ±1% nominal. Ripple: <50mV peak-to-peak. Hold-up time: 20ms minimum. Efficiency: 80% @ full load. Operating temperature range: 0°C to +60°C.
Material Composition
Housing: sheet metal with powder coating. PCB: FR-4. Transformer: silicon steel core with copper windings. Power components: industrial semiconductors.
Structural Characteristics
It features S7-400 single-slot card form factor, front panel status LEDs, AC input terminals, rear backplane connector, and card guide mounting.
Working Principle
AC input is rectified and converted to high-frequency AC, transformed to the required voltage levels, rectified and filtered to produce regulated DC outputs. Control circuitry monitors output and triggers protection on fault conditions.
Installation Requirements
Install in dedicated power supply slot of S7-400 chassis. Connect AC input wiring. Connect protective earth ground. Ensure adequate ventilation.
Usage Notes
Do not exceed input voltage range. Clean vents regularly. Verify output voltages at commissioning. Follow lockout procedures before servicing.
