BENDER IR125Y-4 insulation monitoring device

Product Description

The Bender IR125Y-4 is a specialized insulation monitoring device designed to safeguard unearthed AC and DC control circuits (IT systems). It operates by continuously monitoring the insulation resistance within these circuits, providing early detection of insulation faults that could potentially lead to electrical hazards or system failures.

Key Features and Specifications

• Active AMP Measuring Principle: Unlike passive methods, the IR125Y-4 employs an active measuring principle, enabling the detection of both symmetrical and asymmetrical insulation faults.

• Supply Voltage: The device draws its power directly from the system under monitoring, eliminating the need for an external power source.

• Adjustable Threshold: The trip threshold can be adjusted within a range of 10-200 kΩ to accommodate various system requirements.

• Alarm Functions: The IR125Y-4 provides visual and relay-based alarms to alert operators of insulation faults.

• Compact Design: The device features a compact and rugged design, making it suitable for installation in various environments.

Benefits

• Early Fault Detection: By continuously monitoring insulation resistance, the IR125Y-4 can detect insulation faults at an early stage, preventing potential equipment damage and downtime.

• Enhanced Safety: Early detection of insulation faults helps to minimize the risk of electrical shocks and fires.

• Reliable Performance: The device is built to withstand harsh operating conditions and provides reliable performance over its lifetime.

• Easy Installation and Operation: The IR125Y-4 is relatively easy to install and configure, reducing installation time and costs.

Precautions

• Correct Installation: Ensure that the device is installed according to the manufacturer's instructions to guarantee accurate measurements and reliable operation.

• Environmental Considerations: Avoid exposing the device to excessive heat, humidity, or vibration, as this may affect its performance.

• Regular Maintenance: Periodic inspection and calibration are recommended to maintain optimal performance.
