Bender IRDH265 IRDH365 isolated power

Bender IRDH265 IRDH365 isolated power 

 For IT AC systems, for IT AC systems with galvanically connected rectifiers

and IT DC systems (isolated power)

  Extended voltage range via coupling devices

  Automatic adaptation to the existing system leakage capacitance

  AMP measuring principle

  Two adjustable response ranges

  LCD display

  RS-485 interface

  Connection monitoring

  Automatic self test

The IRDH265 and IRDH365 ISOMETER®s monitor the insulation resistance of IT

3(N)AC, AC/DC and DC systems. The AC systems may include extensive DCsupplied

loads (e.g. rectifiers, converters, thyristor-controlled DC drives, see

2.3). The devices automatically adjust to the system leakage capacitance.

Coupling devices are available to extend the voltage range.

The IRDH265 ISOMETER® is fitted into a standard plastic casing suitable for

DIN rail mounting according to DIN EN 50022 or for screw mounting. The

IRDH365 ISOMETER® is fitted into a flush-mounting casing, 144x72 mm (WxH).
