BENDER IRDH575B1‑4227 | ISOMETER Insulation Monitor 20‑150 V IT‑System
Product Introduction BENDER IRDH575B1‑4227 is an ISOMETER® insulation monitoring device built for ungrounded 20‑150 V IT‑systemsfournais-b…. Field teams deploy this panel‑mount unit to catch first‑insulation‑fault events before phase‑to‑ground short circuits develop. In deployments of mixed AC‑DC drive systems, we found leakage capacitance can skew raw resistance readings.This unit auto‑adapts to system leakage capacitance up to 500 µF…
