PRODUCT DESCRIPTION

When the insulation resistance from system to ground falls below the set response value, 

the alarm relays switch and the alarm LEDs activate. Two separately adjustable alarmcontacts

 can be set to a prewarning and main warning alarm. The measured value is indicated

IRDH-275B-435 BENDER


This device meets or exceeds the requirements of NEC 250.21(B) and CEC 10-106(2) for 

ground detectors in ungrounded AC systems, as well as the upcoming 2014 requirement 

of NEC 250.167(A) for ungrounded DC systems.

The IRDH275 monitors for ground faults in ungrounded single-phase AC, three-phase AC, 

and DC systems by monitoring the system's insulation resistance. It may be connected to 

systems of up to 793 VAC / 650 VDC. Voltage coupler accessories extend this range. The 

AMP Plus measuring principle utilized by the IRDH275 meets the requirements of modern 

power systems, including pure DC systems, systems with rectiffers, and systems with 

variable frequency drives (VFDs). In systems with high leakage capacitances, the IRDH275 

automatically adapts itself to ensure an accurate reading.

The IRDH275 features a digital display showing the system's insulation resistance'in 

real-time. All settings are changed via the device's built-in menu. The IRDH275 utilizes an 

external supply voltage for power, which allows deenergized systems to also be monitored.

For

 a panel mounted version, please refer to the IRDH375.

When the insulation resistance from system to ground falls below the set response value, 

the alarm relays switch and the alarm LEDs activate. Two separately adjustable alarmcontacts

 can be set to a prewarning and main warning alarm. The measured value is indicated

 on the LCD display or an externally connectable measuring instrument. A latching 

setting ("fault memory") allows the device to reset automatically or require a manual reset.

 An external and internal test/reset can be activated remotely or on the device. A 

comprehensive INFO menu displays additional information such as the system's leakage 

capacitance.

The IRDH275 continuously monitors the equipment ground connection to ensure proper 

operation. The device's easy-to-use onboard menu manages all settings via the detailed 

LCD screen.
