ZJJ DC insulation monitoring relay monitorsthe insulation of the DC bus, and it sendsalarm signal when the bus-to-groundinsulation drops to a certain value,also it ispanel mounted type,and the relay has a high-sensitivity grounding resistance monitoringand display circuit, it is great significance forthe safe operation of the DC system.
Monitoring of the DC circuit bus barinsulation resistance RF to LCD screen display resistance value.
Bridge balance method for resistancemeasurement.
Adjustable response value ranges of 0-100k�©.
Smaller short-circuit grounding current forsafe operation.

Flat Cable M&P is able to support a full line of flat cable and flat ribbon cable for electronic applications. Providing both power and data transmissions, flat cables are mainly used for internal connections within the equipment. They are available in a wide range of configurations to accommodate different connection and data transmission requirements and the range of sizes of the equipment using the cables. Flat cables provide consistent performance due to their layout and the spacing between the cables and are lighter, thinner and more flexible than other cables. Features of Our Flat Cables & Wire * Flat, ribbon and twisted configurations, with different levels of flexibility. * Shielded or jacketed cable to reduce signal interference. * Range of pitches and pin configurations to accommodate the application requirements. * Easy to fasten with clamps, adhesive, and tape. We provide custom services, including marking, kitting and custom cable design to provide you with a custom solution for your cabling application. Contact us to find out more about Flat Cables and Wires.
