BENDER IRDH265-422

BENDER IRDH265-422

Product Description

The BENDER IRDH265-422 is an A-ISOMETER, part of the IRDH series of insulation monitoring devices. Its primary function is to continuously monitor the insulation resistance of ungrounded AC (IT) systems and IT AC systems with galvanically connected DC circuits, as well as ungrounded DC (isolated power) systems. It typically features an LED display for status and measurement readings and allows users to set response values and other functional parameters via control keys. These settings are stored in non-volatile memory.

Product Advantages

BENDER A-ISOMETERs, including the IRDH265-422, offer several key advantages for maintaining electrical system integrity and safety:

• Enhanced Safety: By continuously monitoring insulation resistance, they detect insulation faults early, preventing dangerous touch voltages and reducing the risk of electrical fires.

• Increased System Availability: Early detection of faults allows for proactive maintenance, minimizing downtime and maximizing the operational availability of critical systems.

• Preventative Maintenance: Provides continuous data on insulation degradation, enabling predictive maintenance strategies rather than reactive repairs after a fault occurs.

• Compliance: Helps meet regulatory requirements and safety standards for electrical installations in various industries.

• Diagnostic Capabilities: Offers clear indications of insulation status, simplifying fault location and troubleshooting.

• Monitoring of Various Systems: Capable of monitoring both AC and DC IT systems, making it versatile for diverse applications.
