DM-300-b Rail Mounting Dimmer
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.
It’s 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.
Electric Loads
NOTE
- 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.
Adjustment of minimum power limit
The DM-300/b can 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
DM300/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.
