The Bender IRDH265-3 A-Isometer (art. no. B91068008) is an insulation monitoring device from the Serie 260 range. It watches the insulation resistance of the ship’s electrical network against earth and signals through its relay contacts when resistance falls below a set response value, supporting the alarm and monitoring functions of the vessel’s control system. It is rated for systems of 3AC/AC 0-440 V and DC 0-220 V and takes a 230 V AC supply. Software version D83 V2.5-3 is installed. It is offered in used condition.
