CME420-D-2 Bender

Description

Product name：CME420-D-2 Bender output module

Product details:

The AGH150W-4 coupling device is designed to extend the nomi-nal
voltage range of the A-SOMETERIRDH265-4/RDH365-4/IRDH1065B-4
series to DC 0…1760 V. The coupling device isconnected to the system
being monitored by two poles and con-nected to the terminal AK of
the A-ISOMETER by means of theterminal AK160.

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 rectifiers, 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.

The currently measured insulation resistance is indicated on the LC display. In this way
any changes, for example when circuits are connected to the system, can be recognised
easily. When the value falls below the preset response values, the response delay “ton”
starts. Once the response delay “ton” has elapsed, the alarm relays “K1/K2” switch and the
alarm LEDs “AL1/AL2” light up. Two separately adjustable response values/alarm relays
allow a distinction to be made between prewarning and alarm. If the insulation resistance
exceeds the release value (response value plus hysteresis), the alarm relays return to their
initial position. Insulation faults are distinguished according to AC and DC faults (indication ±).
In the event of insulation faults on the plus or minus conductor, the corresponding +/- symbol is
activated on the display. If the fault memory is enabled, the alarm relays remain in the
alarm state until the reset button is pressed or until the supply voltage is switched off.
The device function can be tested using the test button. The parameterisation of the device
can be carried out via the LC display or the function keys integrated in the front plate.
