Mean Well ICL-28R AC Inrush Current Limiter 28A
Overview
The ICL-28 is a 28A inrush current limiter that can be used to reduce the high starting current due to capacitive load causing the circuit breaker to be false triggered. Several power supplies can be installed on the same AC line after the implementation of an ICL-28.

Test conditions and notes3
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
- 3. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ
What does the Mean Well ICL-28R do?
The ICL-28R is an AC inrush current limiter designed to reduce high startup current on compatible AC-powered equipment. For this model, it provides 48A inrush current limiting and supports 28A continuous current operation.
What input range is supported by the ICL-28R?
This model is rated for 180 to 264VAC input. It is intended for AC applications within that voltage range and has an AC input power rating of 6440VA.
How is the ICL-28R different from a basic NTC inrush limiter?
The ICL-28R combines a limiting resistor with an internal relay and control circuit: at power on it limits inrush to 48A for 150±50ms, for up to 3 cycles per minute. That makes it a dedicated DIN rail inrush limiting solution with continuous current capability up to 28A.
Is the ICL-28R suitable for industrial environments?
Yes, this model is built for industrial use with a wide operating temperature range of -30°C to +70°C (with load derating per the derating curve). It also supports operation at altitudes up to 5000 meters and includes an internal thermal fuse.
What kind of protection and compliance does the ICL-28R include?
The ICL-28R includes an internal thermal fuse intended to protect against overload and fire risk. It is approved to LVD BS EN/EN62368-1 and meets EMC standards including EN55032 Class B and EN61000-4 series requirements listed for this model.
Is the ICL-28R compatible with DIN rail control panels?
Yes, the ICL-28R is designed for DIN rail mounting on TS-35/7.5 or TS-35/15 rail formats. Its compact 52.5 x 90 x 54.5 mm housing helps it fit into space-conscious panel layouts.
