- Output Terminal Block: Bolt-type terminals that support 4 A single-channel or multi-channel parallel output.
- Protection Circuit: Integrates overvoltage, undervoltage, overcurrent, short-circuit, and reverse polarity detection circuits.
- Heat Sink: A metal heat sink is directly attached to the power conversion chip, combined with natural convection heat dissipation.
- Identification Label: Includes model number, input/output specifications, warning signs, and certification marks.
4. Typical Application Fields
| Industry | Specific Applications |
|---|---|
| Industrial Automation | Power supply for PLCs, DCS, field instruments, and sensors |
| Power Systems | Power supply for generator control units and frequency converter front-ends |
| Oil and Gas | Power supply for wellhead control cabinets and valve drives |
| Marine and Offshore Engineering | Power supply for marine automation systems and offshore platform control cabinets |
| Transportation | Power supply for rail transit and railway signal systems |
| Manufacturing | Power supply for robots, CNC machine tools, and packaging equipment |
5. Installation and Maintenance Guidelines
5.1 Installation
- Location Selection: Ensure the installation environment has good ventilation and avoid direct sunlight or high-temperature accumulation.
- Fixing: Use screws to fix the chassis to the reserved holes in the cabinet or panel, keeping it level.
- Wiring:Grounding: The metal housing of the chassis must be reliably grounded to prevent electromagnetic interference and safety hazards.
- Use thick wires (≥ 10 mm²) for the input end and install anti-reverse connection diodes.
- Use bolt terminals with nominal current for the output end to ensure secure fastening.
- Make connections according to the wiring diagram in the product manual (marked with “IN+, IN-, OUT+, OUT-”).
- Inspection: Before power-on, check whether all wiring is secure and the polarity is correct, and confirm that the protective cover is properly installed.
5.2 Commissioning
- Voltage Monitoring: Use a multimeter or on-site monitoring system to confirm that the output 24 V DC is stable within the rated range.
- Load Testing: Operate under rated load (4 A) for 5 minutes and observe whether overcurrent or over-temperature alarms occur.
5.3 Maintenance
| Maintenance Item | Recommended Cycle | Operation Points |
|---|---|---|
| Visual Inspection | Monthly | Check for dust, corrosion, or mechanical damage on the chassis. |
| Wiring Tightening | Every 6 months | Use a torque wrench to check terminal bolts to prevent poor contact due to loosening. |
| Heat Sink Cleaning | Annually | Use a soft brush or compressed air to remove dust from the heat sink and maintain heat dissipation efficiency. |
| Functional Self-Test | Annually | Verify the normal operation of overvoltage, undervoltage, and overcurrent protection through the built-in self-test function or external instruments. |
| Replacement of Aging Components | According to service life (≥ 5 years) | If capacitor bulging or diode aging is found, replace them in a timely manner. |
