Information
Overview
Manuals
Common Applications
Product Precautions
The ICRM-7 limits input inrush presented to compatible DECS digital excitation-control hardware when the source impedance is low or switched.
- Compatible with DECS-100 and DECS-150
- 90–277 Vac or 90–300 Vdc input
- 9 Aac current rating
- Vertical mounting with ventilation openings clear
The ICRM-7 is inserted between the operating-power source and the compatible DECS voltage regulator to reduce startup inrush. Its three IN/OUT paths are connected to the regulator output terminals identified in the Basler manual, and the enclosure must remain vertically mounted for airflow. The module contains no user-serviceable parts and is replaced if troubleshooting confirms failure.
Important Notice: Confirm part number 9387900103, source voltage, DECS model, wiring and vertical mounting orientation before installation.
BASLER ELECTRIC ICRM-7 Manuals & Downloads
BASLER ELECTRIC ICRM-7 Official Manufacturer Manual (PDF)BASLER ELECTRIC ICRM-7 Installation & Commissioning Guide (PDF)
The first document reproduces applicable official manufacturer pages unchanged; the second provides a separate evidence-led installation and commissioning workflow.
DECS-100 excitation
Inrush-current reduction ahead of a compatible DECS-100 operating-power input.
DECS-150 excitation
Controlled startup of a compatible DECS-150 supplied from a low-impedance or switched source.
Generator retrofits
Documented upgrades where the approved excitation design specifies an ICRM-7 between source and regulator.
Maintenance replacement
Like-for-like replacement after resistance checks identify a failed non-serviceable ICRM module.
Read the applicable BASLER ELECTRIC instructions before work. Verify ICRM-7 and the installed system configuration before isolation or replacement.
1
Record the ICRM-7 marking and Basler part number 9387900103 before work.
2
De-energize every connected source and wait at least five minutes before handling.
3
Verify that the operating-power source is within the published AC or DC range.
4
Map every IN and OUT conductor to the approved DECS wiring diagram before removal.
5
Mount the ICRM-7 vertically with its upper and lower ventilation openings clear.
6
Treat the enclosure as hot during operation and provide the required clearance.
7
Check each IN/OUT path and replace the module if fault testing confirms failure.
8
Energize under control and record stable regulator startup and acceptance results.
Technical notes
The ICRM-7 is inserted between the operating-power source and the compatible DECS voltage regulator to reduce startup inrush. Its three IN/OUT paths are connected to the regulator output terminals identified in the Basler manual, and the enclosure must remain vertically mounted for airflow. The module contains no user-serviceable parts and is replaced if troubleshooting confirms failure.
