ISOMETER isoLR275 with AGH-LR

• Insulation monitoring device for AC and DC IT systems
• Application main circuits with low-resistance insulation level
• Separately adjustable response values 200 Ω…100 kΩ
• Isometer disconnecting relay for the operation of several ISOMETER® in interconnected IT systems
• History memory with real-time clock for storing alarm messages with date and time

The isoLR275 ISOMETER in conjunction with the AGH-LR coupling device monitors the insulation resistance of IT systems. It is suitable for universal use in 3(N) AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads, such as converters or thyristor-controlled DC drives. The adaptation to the existing system leakage capacitances takes place automatically.

Only use the AGH-LR coupling device supplied with the device for adaptation of the nominal voltage range.

isoLR275 can share the BMS bus with other bus devices
