CJRQ-B Marine Plate Electric Heater:
Serviceable range:
1. Voltage:AC220V Frequency:50/60Hz
2. Ambient temperature:-40℃～40℃air relative humidity is not more than 90 precents.
Basic Parameters:
1. The insulation resistance should not be lower than 500MΩ when it is in the cold condition(indoor 18-20℃).
2. The insulation resistance should not be lower than 200MΩ when it is in the hot condition (tallest work temperature).
3. The insulation resistance should not be lower than 200MΩ when it is in the hot and humid conditions.
4. After the water immersion experiment, the electric hot plate has been immersed in water for 1 hour holistically then take out for 2min, the insulation resistance should not be lower than MΩ.
