Universal PWM Dimmer

The DMS-500-X universal PWM dimmer is designed for smooth, flicker free dimming of all constant voltage LED modules, including Flexible and Rigid LED Strips, Rope Light, Rigid Light Bars, Under-cabinet Lights, Wall and Ceiling Fixtures and also AC/DC MR16 bulbs.  In addition this dimming module will also control; 12V/24V incandescent and halogen bulbs.

There are many approaches to dimming LED's, but probably the best is PWM (Pulse Width Modulation). Like triac based AC dimming, the PWM approach turns the current to the LED module On and Off at certain frequency. A longer 'On time' will result in a brighter LED output, while a shorter 'On time' will result in a dimmer LED output.  The electronic circuitry of the DMS-500-X is well protected with features such as No-load, short-circuit, overload and overheat protection. The standby consumption of the unit is only 7mA.

DMX-500-X is ideal dimmer for any application which calls for low voltage DC lighting. It is ideal for home as well as commercial and industrial applications. It is used in recreational vehicles (RV), mobile homes and other large vehicles, such as buses and trucks. PWM Dimmer is ideal for use in marine environment such as ships, boats, yachts, sailboats and boat homes since it performs superbly whether powered by power supply or battery. It can also be used for interior lighting in aircraft.
Other applications include medical, laboratory and other specialty lighting. The DMS-500-X is designed for the flicker-free dimming of any 12/24V DC constant voltage LED module such as:

This unit meets all UL1310 requirements.
