Insulation protection relay DCG-UB1K-ARH

DCfor feederDIN rail

GYDCG-UB1K-ARH is a DC-to-Ground insulation monitoring module based on the principle of the unbalanced bridge, which has monitoring and protection functions in one. The GYDCG-UB1K-ARH Insulation Monitor can monitor the insulation resistance value of the positive and negative poles of the DC floating system to the ground, ranging from 0Ω to 10MΩ; at the same time, it can also detect the DC voltage value, ranging from 0V to 1000V. GYDCG-UB1K-ARH is equipped with a high-voltage grounding switch, which can realize the online on-off function, that is, when the module is powered off, reset, and stops working, its high-voltage switch to the ground is disconnected, and it is completely separated from the ground. The DC-to-ground high voltage test is not higher than 4200Vdc. -High voltage grounding switch -Widely power supply range -Widely insulation monitoring range (100V~1000VDC) -Insulation monitoring equipment self-test -Adaptive capacitance to ground -Convenient parameter setting -Remote monitoring and management -Monitor positive and negative poles -Ground insulation resistance -Voltage reverse polarity alarm Power supply:10-30VDC, Power 3w DC voltage range:0V~1000V DC voltage measurement accuracy :≤2V+0.3% Insulation resistance measurement range: 1KΩ~10 MΩ (DC System voltage:100V~1000V) Off-line pressure test:<2mA Maximum relay switching voltage:250VAC/30VDC Maximum relay switching current:3A Relay contact resistance:<100mΩ Relay insulation resistance: - 100MΩ Standard - :IEC 61851-23 (2014-03):2014-11 Humidity - :85% Storage temperature: - – 40°C ~125°C Operating temperature:– 40°C ~75°C
