Performance Parameters:
- Input Voltage: 100 to 240 VAC
- Output Voltage: 5 VDC / 24 VDC
- Output Current: 2.8 A (5V) / 0.4 A (24V)
- Total Power: 14 W
Material Composition:
- Switching power supply circuitry
- Metal chassis with plastic housing
- Screw terminal blocks
Structural Features: The unit mounts directly onto the CJ series backplane. It features screw terminals for AC power input and status indicators.
Working Principle: The unit uses a switching regulator to convert the input AC voltage into stable 5 VDC and 24 VDC outputs. These voltages are supplied to the PLC backplane to power the CPU and I/O modules.
Installation Requirements:
- Mount on CJ series CPU rack
- Connect AC power using screw terminals
- Ensure proper grounding
- Provide adequate ventilation
Usage Notes:
- Verify the input voltage range before connecting power.
- Do not exceed the total output power capacity (14 W).
- Ensure all modules are properly seated on the backplane.
