Marine type AC Net Insulation Monitor

 

 1. Monitor imperfect grounding in vessel power system and alarm output;

 2. Used for continuous monitoring resistance(less than 500V) in power system between vessel and electric circuit, and alarm release once insulation resistance lower than preset value.

 1. Valid measuring range: 0.005-5MΩ, alarm level: 0.01MΩ, 0.03MΩ,0.06MΩ,0.1MΩ;

 2. Alarm output capacity: DC24V/3A or AC220V(Max) 1A, terminal 4 & 5 is normal open, 5&6 is normal close;

 3. In the same power network, it is forbidden to inspect insulation resistance by 2 units meter or other instrument;

 4. This type of meter include one-way and dual structure, while one-way type with transmitting output with 4-20mA, accuracy class: 1%.
