Manufacturer: Daiichi Electronics Co., Ltd.
Model: SGR-L-63 / SDGR-L-63

Features

• This device detects the ground resistance of an ungrounded DC power circuit and outputs a contact signal.
• It directly uses the DC bus voltage of the measured circuit and calculates the ground resistance using a bridge detection circuit, which eliminates the influence of stray capacitance generated in shipboard wiring systems and similar applications.
• Furthermore, the circuit is designed not to be affected by fluctuations in power supply voltage, allowing for high-sensitivity and stable performance.
