Bender IRDH275B-435 Insulation Monitoring Equipment  

Product Details Introduction

Bender IRDH275B-435 is an IT system insulation monitoring device from Bendel, Germany. It has been discontinued and focuses on high anti-interference and intelligent monitoring.

Brand and model: Bender IRDH275B-435 from Germany, A-ISOMETER series, DIN rail installation.

Applicable system: Monitor ungrounded IT systems, including AC/DC/hybrid systems, suitable for complex loads such as frequency conversion and rectification.

Voltage range: nominal AC 0-793V, DC 0-650V; Can be extended to high-voltage scenarios with couplers.

Measurement principle: AMPPlus technology, automatically adapts to leakage capacitance, and remains accurate even under high interference.

Insulation range: 1k Ω -10M Ω, dual threshold independently adjustable, supporting warning and fault two-level alarm.

Power supply specifications: Wide voltage range of 88-264VAC/77-289VDC, power consumption of approximately 8VA.

Output interface: 2-channel SPDT relay (250VAC/5A), 0/4-20mA isolated current output.

Communication capability: Isolated RS485 (BMS protocol), supports access to PLC/SCADA remote monitoring.

Event record: Version B can store 300 alarm events with timestamps for easy traceability.

Self checking function: Built in automatic self checking to ensure reliable operation of the device itself.

Display operation: Pure text display, Info key can check parameters and leakage capacitance.

Protective installation: DIN 35mm rail, terminal anti electric shock protection, compatible with switchgear.

Environmental adaptation: Working temperature -40 ℃ -+60 ℃, anti vibration, EMC meets industrial standards.

Compliance certification: meets NEC, CEC and other standards, suitable for markets such as North America and Europe.

Alternative reference: discontinued models, commonly used in stock, upgrading can consider the IRDH375/575 series.

In summary, IRDH275B-435, with AMPPlus anti-interference measurement, dual threshold alarm, and event recording as its core, is a classic device for IT system security monitoring, suitable for key scenarios such as hospitals, ships, and factories.
