PREFACE
The MDU13 is a PWM Dimmer designed to
use with single color Equator series and with
single or three-color of Conus, Convex and
Plaque series underwater LED lights. The 3
control outputs enable the dimming of different
series of underwater LED lights by using of
one push-button switch.
FEATURES
•3 Control Outputs
•Adjustable PWM Frequency
•Wide Range Power Supply
•Low Power Consumption
•Polarity Protection
•Transient Protection
•Short Circuit Output Protection
•Simple Installation
PRECAUTIONS
•The PWM Dimmer has to be installed and
used in accordance with the instructions of
this manual only.
•The power supply has to be disconnected
before installation.
•Avoid installing the PWM Dimmer in
extremely hot places and near appliances
generating strong magnetic fields.
•Do turn power off immediately and refer
servicing to qualified service personnel if
the PWM Dimmer does not operate
normally following the operating
instructions.

INSTALLATION
The PWM Dimmer kit consists of the following components:
•PWM Dimmer MDU13
•2 x cable gland M12
•Operating Instructions with Declaration of Conformity and Warranty conditions
The MDU13 has to be installed on suitable location inside of the vessel.
Avoid the installation in extremely hot places and near appliances generating strong magnetic fields.
The installation has to be realized by a qualified personnel.
Note:
•The main DC power supply of the vessel has to be switched off before installation.
Power supply connection
The power supply has to be connected through the switch (not included) and protected by a fuse (not
included) to the DC IN terminal-block connector with correct polarity. The power supply voltage has to
be from 10 - 30Vdc.
PWM control outputs connection
The 2 control wires of single-color LED lights have to be connected to the one of CH-1 to CH-3
terminal-block connectors.
The 6 control wires of three-color LED lights have to be connected to the CH-1, CH-2 and CH-3
terminal-block connectors.
Depend on the LED lights series, the DIP-switches have to be adjusted as described in the table
below:

CONTROLS
Single-color models
The push-button switch is used to turn-on and turn-off the underwater light and to control the
luminosity.
Turning on / off
Press the push-button switch momentary.
Dimming
When the light is on, press the push-button switch longer until the desired power is achieved.
Turning on minimum
When the light is off, press the push-button switch longer (e.g. one second or more) until the light is
turned on at minimum power.
Set default
Press the push-button switch for min. 40 seconds or until the light is turned off.
Three-color models
The push-button switch is used to turn-on and turn-off the underwater light and to control the mode of
lighting and luminosity.
When the light is turned-off the color or mode of lighting can be changed sequentially by pressing
the push-button switch for 2 seconds:
Sequence of lighting
Custom Color
Full RGB
Cool White
Bluish White
Red
Green
Blue
Rainbow Color Spectrum
Turning on /off
Press the push-button switch momentary.
Changing the color or mode of lighting
When the light is turned-off press the push-button switch for 2 seconds.
Setting the Custom Color
At the selected Rainbow Color Spectrum mode press the push-button switch momentary to turn the
light off. After that press the push-button switch for 5 seconds or until the light is switched to the
selected color and then the Custom Color is set and selected.
Dimming
When the light is turned-on press the push-button switch until the desired illumination is achieved. By
another pressing of the push-button switch the luminosity will increase to the maximum illumination.
Set default
Press the push-button switch for min. 40 seconds or until the light is turned off.
