Technical Specifications Universal AC/DC IT system monitoring; Adjustable response values; Modbus communication available; Relay alarm output.
Functional Features Insulation resistance trend monitoring; Pre-warning and fault alarm; Integrated self-test; Fault memory; Bus communication option.
Application Scenarios Data center UPS, marine vessels, battery energy storage, medical locations, industrial ungrounded power networks.
Performance Parameters High measurement accuracy; Fast fault detection; Remote status reading via communication.
Structural Characteristics DIN rail mounted module, front display and operation buttons, LED indicators, wiring terminals.
Working Principle Apply measuring signal to the isolated power network, calculate insulation resistance to ground. When insulation degrades below set value, activate alarm contacts and send status over bus.
Installation Requirements DIN rail installation; Separate measuring wiring from high power cables; Proper system grounding of the monitor itself.
Usage Notes Verify system is IT ungrounded network before commissioning. Perform regular function test.
