Insulation protection relay JY series

DCfor feederfor electric vehicle charging stations

The JY series insulation monitoring device has three types: JY1000, JY1000-C2. The JY1000 and JY1000-C2 are suitable for EV DC charging systems, photovoltaic systems, energy storage systems, DC power grids, and other DC systems under 1000V. The JY1000-C2 DC insulation monitor is special for electric vehicle DC charging system.




Common Feature of JY series DC Insulation Monitor

• Fully functional

Integrated function: charging pile voltage measurement, insulation resistance monitoring, car side voltage measurement, current measurement, and many other measurement functions.

• Wider power supply range

Compatible with 12V or 24V power supply, power supply range 10~30V.

• Wider insulation monitoring range

Insulation resistance monitoring can be realized in the DC range of 100V~1000V, and the resistance monitoring range is
0KΩ~10MΩ.

• Real-time monitoring of insulation resistance

When the insulation monitor is turned on, it will continuously monitor the insulation resistance of the positive and negative poles to ground and is not affected by the insulation resistance of the positive and negative poles. The influence of resistance symmetry is eliminated, and the monitoring data is updated in real time.

• Higher reliability

In the case of low-frequency fluctuations in DC voltage, the insulation resistance monitoring results will not be affected.

• The internal resistance to ground is larger

The internal resistance of the insulation monitoring module to ground is >600KΩ.

• Faster monitoring speed, adaptive to ground capacitance

Under the condition that the capacitance of the positive and negative poles to ground does not exceed 3uF respectively, rapid insulation resistance monitoring is achieved
The monitoring period is between 0.7 seconds and 2.5 seconds. The larger the capacitance to ground, the longer the monitoring period.

• Higher monitoring accuracy

When the capacitance to ground is small, the monitoring accuracy can be within 1%.

• Parameter setting is more convenient.

All communication parameters can be set using dial switches (including communication address, baud rate, parity and even
Verification method).

• Single channel and dual-channels type optional

The JY1000 are single -channel insulation monitoring deive. The JY1000-C2 and DCG-UBCH2-LZ are dual-channels insulation monitoring device.

• Monitoring of the DC circuit bus bar insulation resistance RF to earth.
• Simple device setting by DIP switch.
• 35 mm din rail mounting or screwing fixing mounting
