BENDERSUR353Z Bender

Description

Product name：BENDERSUR353Z Bender Power module

Product details:

Monitoring for unearthed AC and DC
systems with galvanically connected
rectifiers or inverters
• Measurement of the nominal system
voltage Un (True RMS) with undervoltage
and overvoltage detection
• Measurement of DC voltages system to
earth (L+/PE and L-/PE)
• Automatic adaptation to the system
leakage capacitance up to 1000 μF
• Automatic device self-test with connection
monitoring
• Selectable start-up delay, response delay
and delay on release
• Two separately adjustable response value
ranges of 1…500 kΩ (Alarm 1, Alarm 2)
• Alarm signalling via LEDs (AL1, AL2), a
display and alarm relays (K1, K2)
• N/C operation or N/O operation selectable
• Measured value indication via multifunctional LCD
• Fault memory can be activated
• RS-485 (galvanically isolated) including
the following protocols:
– BMS interface (Bender measuring device
interface) for data exchange with other
Bender components
– Modbus RTU
– isoData (for continuous data output)
• Password protection to prevent
unauthorised parameter changes

– LED “ON” (operation LED) flashes in case of interruption of the
connecting wires E/KE or L1/+ / L2/- or system fault.
2 – Alarm LED “AL1” lights when the values fall below the set response
value Alarm 1 and flashes in case of interruption of the connecting
wires E/KE or L1/+ / L2/-, in the case of system faults as well as
overvoltage (can be activated).
3 – Alarm LED “AL2” lights when the values fall below the set response
value Alarm 2 and flashes in case of interruption of the connecting
wires E/KE or L1/+ / L2/-, in the case of system faults as well as
undervoltage (can be activated).
4 – LC display
5 – Test button “T”: Call up self-test
Arrow up button: Change parameters, move upwards in the menu
6 – Reset button “R”: Delete stored insulation fault alarms
Arrow down button: Parameter change, move downwards in
the menu
7 – Menu button “MENU”: Call up the menu system
Enter button: Confirm parameter changes

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.
