DC protection relay DCG-UBCW2K

for electric motorsfor feederDIN rail

GYDCG-UBCW2K series is a DC-to-ground insulation monitoring module based on the principle of unbalanced bridge, which has monitoring and protection functions in one. It 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 2000V. The insulation resistance monitoring can only be realized when the DC voltage is between 100V and 2000V. When the DC voltage is less than 100V, or the insulation monitoring is not enabled, the insulation resistance read is 65535 (invalid number). When the measured value is greater than 10MΩ, the value received by the communication is 60000 (infinity). -Widely power supply range -Widely insulation monitoring range (0V~2000VDC) -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~2000V DC voltage measurement accuracy: ≤2V+0.3% Insulation resistance measurement range :1KΩ~10 MΩ (DC System voltage:100V~2000V) 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
