IV. Typical Application Scenarios

Petrochemical: 24V system power supply for DCS control cabinet, I/O card power supply

Power (thermal power / hydropower): TPS/UCN control station, boiler / turbine auxiliary control system

Papermaking / pharmaceutical / water treatment: Field instruments, valve positioners, sensors power supply

Metallurgy / cement: 24V regulated power supply in high-temperature, high-dust environments

General industrial automation: PLC, touch screen, sensors, actuators power supply

V. Installation and Wiring Tips

Installation location: DIN rail installed in the control cabinet, away from strong heat sources, ensure ventilation.

Input wiring:

Connect 12–48VDC, pay attention to positive and negative poles

It is recommended to add a fuse + surge protector at the front end

Output wiring:

24VDC output to system bus, I/O card, field equipment

When paralleling multiple units, connect the same polarity at the output end, the wire diameter should be as consistent as possible, and the length should be as short as possible

Heat dissipation and environment:

Control the ambient temperature within -20℃ ~ +60℃

Avoid dust, oil stains, corrosive gases

VI. Maintenance and Fault Troubleshooting

Daily maintenance

Quarterly: Check terminal connection tightness, clean surface dust, check indicator light status

Annual: Load measurement of output voltage, redundant switching test

Common faults

PWR light not on: abnormal input voltage, fuse blown, reversed wiring

Low output voltage: heavy load, environmental over-temperature reduction, input voltage too low

FAULT light on: output short circuit, overcurrent, overheating

Redundant switching failure: incorrect parallel connection wiring, module model not consistent, load imbalance
