494-311

Lights Dimming Module

│Specification│Pinouts│Installation Note│

Features and Functions

Lightweight, Small Size, Modular design
PWM driven dimming steps
Soft-Start lamp driver to reduces lamp load inrush current
Multiple dimming modules can be daisy chained to achieve higher light's pool

Description

The 494-311 Lights Dimming Module provides low drop-out voltage conversion from Pulse-Width Modulate line signal to lamp drive current. It also equipped with soft-start circuit that greatly reduce the cool start system inrush and the high input impedance port allows multiple unit daisy chained when light's pool application is needed. The source of PWM signal may be obtains from our SL-1369 Lighting Control Module or SP67 SMartPack™

Application

Low inrush On/Off lamp driver
PWM controlled Continue dimming lamp driver
