- Inspect the input and output connections regularly (recommended once a month), ensuring they are tight and free of loose or oxidized contacts.
- Monitor the output voltage and current regularly, ensuring they are within the rated range; if there is any abnormality, stop using the module immediately and check for faults.
6.2 Regular Maintenance
- Clean the module’s surface and heat sink every 3 months (for industrial environments) or 6 months (for general environments), using a soft brush or compressed air to remove dust and debris, ensuring good heat dissipation.
- Check the module’s internal components every 12 months (by professional technicians), including capacitors, resistors, and semiconductors, for signs of aging or damage; replace damaged components in a timely manner.
- Calibrate the module’s output voltage and current every 12 months, ensuring the accuracy of the output parameters.
6.3 Precautions for Use
- Do not exceed the rated input voltage, output voltage, and output current of the module, so as not to damage the module.
- Avoid installing the module in an environment with high temperature, high humidity, dust, or corrosive gas, which will affect the module’s performance and service life.
- When replacing the module, ensure that the input power is cut off and the module is completely cooled to avoid electric shock or burns.
- Do not disassemble the module without authorization; otherwise, the warranty will be invalid, and potential safety hazards may be caused.

7. On-Site Fault Maintenance Cases
The following are 3 real on-site fault maintenance cases of the 4NIC-LJ series DC-DC power modules, providing practical reference for users to solve common faults:
Case 1: No Output Voltage (Model: 4NIC-LJ60, Output: DC6V10A)
Fault Phenomenon: The module is powered on, but there is no output voltage, and the indicator light is off.
Troubleshooting Process: 1. Check the input voltage: Measure the input voltage with a multimeter, which is DC110V, within the rated range. 2. Check the input fuse: The input fuse is blown, which is caused by the short circuit of the internal rectifier diode. 3. Maintenance: Replace the input fuse and the damaged rectifier diode, power on again, and the module outputs normally.
Cause Analysis: The internal rectifier diode is aging and short-circuited, causing the input fuse to blow, resulting in no output voltage.
Case 2: Output Voltage Fluctuation (Model: 4NIC-LJ120, Output: DC12V10A)
Fault Phenomenon: The module’s output voltage fluctuates between 11.5V and 12.5V, which affects the normal operation of the connected equipment.
Troubleshooting Process: 1. Check the input voltage: The input voltage is stable at DC110V, no fluctuation. 2. Check the output load: The output load is normal, no overload or short circuit. 3. Check the internal voltage stabilization circuit: The voltage stabilization capacitor is aging, resulting in poor voltage stabilization effect. 4. Maintenance: Replace the aging voltage stabilization capacitor, power on again, and the output voltage is stable at 12V±0.1V.
Cause Analysis: The voltage stabilization capacitor is aging, the capacitance decreases, and the voltage stabilization effect is reduced, leading to output voltage fluctuation.
Case 3: Module Over-Temperature Alarm (Model: 4NIC-LJ300, Output: DC24V15A)
Fault Phenomenon: The module’s over-temperature alarm is triggered during operation, and the module automatically shuts down.
Troubleshooting Process: 1. Check the heat dissipation environment: The module is installed in a closed space, and the heat cannot be dissipated in time. 2. Check the heat sink: The heat sink is covered with a lot of dust, which affects heat dissipation. 3. Maintenance: Clean the dust on the heat sink, install a cooling fan to improve the heat dissipation environment, power on again, and the module operates normally without over-temperature alarm.
Cause Analysis: Poor heat dissipation environment and excessive dust on the heat sink lead to the module’s operating temperature exceeding the limit, triggering the over-temperature protection.
8. FAQ (Frequently Asked Questions)
| Question | Answer |
| What should I do if the 4NIC-LJ series module has no output after power-on? | First, check whether the input voltage is within the rated range (DC90~180V or DC66~160V) and whether the input fuse is blown. If the input voltage is normal and the fuse is intact, check the internal rectifier circuit and power switch tube by professional technicians. Do not disassemble the module without authorization. |
| Can multiple 4NIC-LJ series modules be connected in parallel to increase output power? | Yes, most models of the 4NIC-LJ series (such as 4NIC-LJ1000F, 4NIC-LJ2000F, 4NIC-LJ3000F, etc.) support parallel operation. When connecting in parallel, it is necessary to use a dedicated parallel board to ensure current sharing between modules, and the total output power is the sum of the output power of each module. |
| What is the service life of the 4NIC-LJ series DC-DC power modules? | Under normal working conditions (operating temperature -40℃~+85℃, no overload, good heat dissipation), the service life of the 4NIC-LJ series modules is up to 100,000 hours (MTBF: Mean Time Between Failures). Regular maintenance and care can further extend the service life. |
