Product introduction:
YNY - Ⅲ AC/DC insulation monitor is applicable to DC systems below 1000V and AC ungrounded systems below 1150V. It can be applied to photovoltaic inverters, mining machinery, electrical equipment, electric vehicle charging devices, UPS power supply systems, DC power supply systems in communication industry, and any AC and DC ungrounded systems. The instrument is interlocked with the circuit contactor or the auxiliary contact of the circuit breaker to realize the isolation of the insulation monitor from the power grid when the motor circuit is powered on, and the insulation monitor automatically starts to monitor the insulation of the line when the line is powered off
