INTRODUCTION
The LC-223 is an easy-to-use dimming ballast control module that can be easily installed and operated without requiring specialist knowledge or skills. The brightness of a fluorescent lamp can be controlled using a dimmer, either via digital input or a host controller. The digital input can be used to directly control the light value of the luminous flux in sequence from 10% to 100%, without the need for a remote host controller. 4 kV ESD protection and 2500 VDC intra-module isolation are also provided. When required, communication with the LC-223 is programmable based on the Modbus RTU protocol, with the added benefit that different addresses can be set via hardware configuration.
