RAIL MOUNTING DIMMER 300 Watt LED (REMOTE CONTROL) DM - 300/b

The DM-300/b rail mounting digital dimmer (light adjuster) is an innovative product of digital technology Leading edge & Trailing edge, especially designed to fulfill the needs of professional spaces in the important field of lighting adjustment and energy savings.

Its perfect linearity in lighting adjustment with alternative types of lamps such as Filament LED, Dimmable LED, Dimmable CFL and previous technology lamps (HALOGEN) makes this product unique.

The product can be remotely controlled through one or several distant buttons (any type or company). The output power of the product can be expanded indefinitely by adding amplifiers DM-CHL (1000W per amplifier) thereby making any electrical application possible.


Control: The DM-300/b rail-mounting dimmer has 3 buttons for control and a remote control input:

  • Button: (ON/OFF) It is used to activate and de-activate the electric load.
  • Button: (+ & -) They are used to adjust the lighting intensity and therefore the consumption of the load at the desired point for the operator, from 1% to 100%.
  • Input for wired remote control from one or more parallel buttons for adjusting the lighting intensity.

    - ON/OFF by briefly pressing the push button.
    - Dimming by a long press the push button.

(Phase-Cut Dimming): The DM-300/b enables the user select the type of Phase-Cut Dimming according to the load Leading Edge and Trailing Edge.
In order to select Leading Edge or Trailing Edge long press for 6 sec the following buttons on the device:

  • Leading Edge: (+) and (ON/OFF) The LED indicator will flash GREEN.
  • Trailing Edge: (-) and (ON/OFF) The LED indicator will flash RED.


Adjustment of minimum power limit: The Dimmer DM-300/b an adjust the lower threshold of the lightning intensity of the Dimmable LED lamps if it's required. This takes place as follows:

  • Step 1. Long press the ON/OFF for 6 sec and the LED indicator of the DM- 300/b will start blinking orange.
  • Step 2. Press up (+) or down (-) to adjust the lower threshold of the Dimmable LED lamps.
  • Step 3. Press the button ON/OFF briefly once to save the adjustment.

NOTE: When the process is over the LED indicator on the DM-300/b will turn green.Repeat the steps in order to re-adjust the lower threshold if it's required.

INSTALLATION INSTRUCTIONS:

•  To prevent any accidents, installation must be carried out by qualified personnel.
•  Improper installation or use can result in electric shock or fire.
•  Install the product according to the electrical draft of installation.
•  Do not mix different types of loads (Capacitive - Inductive). Especially for LED lamps it is recommended to only use the same type.
•  In case of using the product with electronic transformer, it must be compatible with semiconductor switching devices (dimmers).
 

Electric Loads



  • In order to control inductive loads such as electromagnetic transformers and motors it's mandatory to connect the booster DM-CHL (1000W/50Ηz). Do not try to use the DM-300/b directly..
  • All the settings of DM-300/b, lower threshold-lightning percentage - ON/OFF state, are saved in a EEPROM so in any power outage the dimmer will return in the last known condition.
The product complies with the requirements of the following EU Directives: 
• 2014/30/EE (EMC)  • 2014/35/EE (LVD)

This product should be disposed of in accordance with national laws and environmental protection requirements.
