Product Description
Bender IRDH375B-435 Insulation Monitoring Device
The Bender ISOMETER® IRDH375B-435 is a high-performance insulation monitoring device designed for unearthed AC, AC/DC, and DC power systems (IT systems). It is universally applicable in systems containing rectifiers, converters, and variable-speed drives. Utilizing Bender’s patented AMP Plus measurement principle, this device provides reliable and precise monitoring even in complex installations with high leakage capacitances. The IRDH375B-435 continuously monitors the insulation resistance, providing early warnings for insulation faults, which helps to prevent system downtime, reduce fire hazards, and ensure electrical safety. Its high-resolution graphical display allows for easy configuration and clear visualization of system status and measured values.
