Bender IRDH375B-435 Insulation monitoring instrument
1. Product Overview
Model: Bender IRDH375B-435 (belongs to the IRDH375 series, enhanced insulation monitoring equipment).
Type: Online insulation resistance monitor, designed for ungrounded systems (IT systems), providing high-precision insulation fault monitoring.
Typical applications:
Medical field: medical IT power distribution systems such as operating rooms, ICUs, emergency rooms, etc. (compliant with IEC 60364-7-710 standards).
Industrial scenarios: high-risk environments such as petrochemicals, mining, and ship power systems.
Renewable energy: insulation monitoring of photovoltaic DC systems and battery energy storage systems.
2. Key features
Monitoring range:
Insulation resistance measurement: 1 kΩ ~ 10 MΩ (adjustable alarm threshold).
Voltage adaptation range: AC 0~440V or DC 0~750V (-435 suffix may correspond to specific voltages, please confirm the manual).
Accuracy: ±5% reading (full scale).
Alarm function:
Dual-level alarm: pre-alarm (Warning) and main alarm (Fault), thresholds can be set independently.
Relay output: 2×SPDT (5A/250VAC), supports fault linkage control.
Communication interface:
RS-485 Modbus RTU (default), optional Ethernet or Profibus (need to be customized).
Advanced function:
Real-time waveform display (need to cooperate with Bender special software).
Fault recording: record insulation degradation trend and support post-analysis.
3. Electrical and mechanical specifications
