Product Description

 GYDCG-UBCH2 series products are used for online monitoring dc floating land system is the cathode of insulation resistance of the device, it is based on the principle of the unbalanced bridge, to avoid the balance bridge across the electrodes in the problems of grounding fault cannot be detected at the same time, at the same time, this series product can change greatly in the dc voltage, under the condition of accurate measurement of electrical resistance, and short measurement period, adopt the method of adaptive adjustment measure time, avoid is negative to the influence of the capacitance. This series product is a 200-850-v DC system, measuring conditions 1 kΩ~ 10 mΩresistancerange, at the same time also detects the DC voltage value, the user can through the RS485communication to realize the measured value.
