YNY-IV suit

Used for on-line insulation detection of 3~10V variable frequency drive system...

Product features:
1. Real-time monitoring of power system insulation resistance to ground
2. For DC system, the insulation resistance of positive and negative bus to ground can be reported separately
3. It is applicable to AC system and can measure L/N insulation resistance to ground
4. The external resistance box can be used for insulation detection of 11.5KV AC/DC system
5. When the bus voltage is zero, the insulation resistance of the system to the ground can still be monitored
6. Provide 1-channel RS485 communication signal, standard Modbus_ RTU protocol
7. Provide 2-way relay alarm signal output
8. In parallel application of photovoltaic DC bus, an additional channel of RS485 communication signal can be provided to form a master-slave parallel mode to realize insulation detection of multiple buses
Description
Product introduction:
     YNY - Ⅳ suit is an insulation monitoring suit. The instrument is interlocked with the circuit contactor or the auxiliary contact of the circuit breaker to realize the separation of the insulation monitor from the power grid when the motor circuit is powered on. When the line is powered off, the insulation monitor automatically starts to monitor the insulation of the line. Although the insulation monitor only monitors after the bus is powered off, considering that it is directly connected to the high voltage bus, the insulation monitor is also equipped with a coupler, It is used to protect the line and insulation monitor host
