IRDH275BW-435 Bender

Description

Product name：IRDH275BW-435 Bender output module

Product details:

The Bender IRDH275BW-435 is a high-performance, digital insulation monitoring device designed for unearthed systems (IT systems). It is part of the ISOMETER® family, specifically engineered to monitor insulation resistance in AC, AC/DC, and DC systems.

1. Product Overview

The IRDH275BW-435 utilizes the patented AMP Plus measurement principle. This allows the device to meet the requirements of modern power systems, which often include power electronics (such as variable speed drives and rectifiers) that cause high system leakage capacitances and DC interference.

2. Technical Specifications (Key Parameters)

3. Product Advantages

• Universal Application: Suitable for pure AC systems, DC systems, and “mixed” systems containing high-frequency interference from converters.

• AMP Plus Technology: Automatically adapts to the system leakage capacitance, ensuring accurate measurements even in complex electrical environments.

• Self-Monitoring: The device continuously monitors its own connection to the earth (PE) and the system (L1/L2), triggering an alarm if a lead is broken.

• Pre-warning and Main Alarm: Features two separately adjustable response values (Alarm 1 and Alarm 2), allowing for early maintenance before a total system shutdown occurs.

• BMS Bus Capability: Can be integrated into a larger Bender communication system for remote monitoring and parameterization.

4. Product Applications

This device is typically used in critical infrastructure where power continuity is essential:

• Industrial Plants: Monitoring motor control centers (MCCs) and production lines.

• Renewable Energy: Photovoltaic (PV) systems and large-scale battery storage.

• Marine & Offshore: Shipboard electrical systems and oil rigs.

• Railway Systems: Signaling and traction power supplies.

• Medical Facilities: Group 2 medical locations (operating theaters and intensive care).

5. Important Considerations (Precautions)

• Installation Safety: Installation must be performed by qualified personnel while the system is de-energized.

• Single Device Rule: In any interconnected IT system, only one insulation monitoring device should be active. Multiple devices will interfere with each other’s measurement signals.

• Wiring Check: Ensure the connection to the functional earth (KE) and protective earth (PE) are separate to allow the device to perform its connection monitoring function correctly.

• Configuration: The response value should be set based on the specific leakage resistance of the installation to avoid “nuisance” tripping.
