Detects symmetrical insulation fault
The A-ISOMETER ® IR 420-D4-2 monitors the insulation resistance of an ungrounded AC Circuits (IT networks 0 - 300 V). In AC circuits existing dc-powered components do not have any influence on the response to this device. By a separate power supply is also a monitoring of the voltage-free system. A password protects against unwanted change the set limit values, or the lead-sealable transparent cover. An insulation monitoring device of Bender is the guarantee for the safe construction of insulated, einfehlersicheren AC supplies.
