This 75w Constant Current, four channel DMX driver from Sunricher features many professional features including RDM Bi-directional communication, adjustable PWM frequency (up to 35KHz), adjustable PWM bit rate resolution of 8bit or 16bit and an adjustable dimming curve either linear or logarithmic with gamma values from 0.1 to 9.9. The driver is very efficient with a high power factor >0.9 at 230v AC and it has an "in built" short circuit protection with automatic recovery after the fault condition is removed.

The unit is compatible with all DMX512 master controllers and it can be used for many professional projects including installation in commercial or domestic premises, however with the features detailed above it is particularly suitable for use in film and TV production. The driver has an adjustable output from 300mA up to 1,500mA and it will control four channel LED products up to a maximum total output load of 75w. This DMX Driver has two modes of operation and can be set to either DMX mode or Master mode. DMX mode is used when the driver is connected to a DMX512 controller and Master mode enables you to test your lighting products and also select a number of dimming levels or built in programs that will run without the need for a DMX controller.  Note: More information on the programs and dimming levels available are detailed in the included Datasheet / instruction manual.

The output current is selectable using the dip switches on the front panel of the driver and the various running options and settings are achieved by using the menu buttons and digital display. The driver can be set to single channel, Dual channel, three channel or four channel modes depending on your requirements.
