High end equipment
Underwater equipment: Charge diving equipment.
4、 Maintenance and upkeep guide
Daily usage standards
Environmental control: Store in an environment with a temperature range of -20 ℃ to 50 ℃ and a humidity of ≤ 85% RH, avoiding direct sunlight or the intrusion of condensed water.
Load matching: Overloading is strictly prohibited (recommended load ≤ 90% rated power) to prevent overheating and damage.
Regular maintenance process
Cleaning: Clean the heat dissipation holes with dry compressed air every quarter to avoid dust accumulation affecting heat dissipation; If contaminated with oil, it can be wiped with isopropanol (concentration ≥ 70%).
Electrical testing: Use a power analyzer to test the output voltage (standard value ± 0.3V) and current (standard value ± 0.1A) every six months. If the error exceeds the standard, it needs to be returned to the factory for maintenance.
Sealing inspection: Conduct an annual air tightness test (pressure 10kPa, leakage rate ≤ 0.1%/min), and replace the sealing ring if there is a leak.
Fault handling plan
Check if the charger is connected to the power source if there is no output, the indicator light is not on, or it is not flashing,
Overheating protection: When the ambient temperature is too high, suspend use and strengthen ventilation, and restore power supply when the temperature drops below 50 ℃.
The red power on indicator light is on, and the charger is connected to the battery, but the charging program does not start. Check the connection between the charger and the battery, and check if the battery is damaged or overdischarged.
