Chapter 1 Introduction
The dimming actuator (hereinafter referred to as Dimmer) is a device dimming the luminaries directly by the
data in the memory, and the data is processed in advance in the programming software according to the
distribution characteristics of the luminaries’ brightness. The control circuit of dimmer transfers the brightness
data value to output voltage or current to control the brightness of the luminaries.
The dimmers products including universal dimmers, 1-10V DC dimmer, 0/1-10V DC dimmer, 350mA LED
dimmer, 4A LED dimmer, 4 channel dimming host ,2 channel 5A dimmer slave, 2 channel and 4 channel Triac
dimmer.
The universal dimmers carry out dimming via phase modulation, which have 3 categories: 1-channel,
2-channels and 4-channels. Max. Power of each channel is 500W for 1-channel and 2-channels dimmers, and Max.
Power of each channel is 400W for 4-channels dimmer. It is able to dim one independent group of luminaries by
1-channel dimmer, 2 independent groups of luminaries by 2-channels dimmer, and 4 independent groups of
luminaries by 4-channels dimmer.
0~10V DC dimming controller with standard DC 0-10V control interface, has 4 independent channels and
one channel can control up to 23 electronic control gears (ECG), such as 23 ECG/18W, 14 ECG/36W, 11
ECG/58W or 23 ECG-T5/24W. The input need connect a 230V AC operating voltage for the device.
0/1~10V DC dimming controller with standard DC 0/1-10V control interface, has 4 independent channels
and one channel can control up to 23 electronic control gears (ECG), such as 23 ECG/18W, 14 ECG/36W, 11
ECG/58W or23 ECG-T5/24W. There is no additional voltage input.
The 350mA LED dimmer with LED constant current drive can drive LED directly, has four channels, each
channel is independent and with two independent output. The output current of each channel can be set by linked
switch current button and channel switch current button and can output 350mA/700mA or 700mA/1A.
The 4A LED dimmer with LED constant voltage drive can drive LED directly, has four channels, each
channel is independent. The input need connect a 12-24V DC operating voltage for the device, the output voltage
depends on the input voltage.
The 4CH dimming host is used with 2CH 5A dimming slave as well. The dimming slave takes the leading
edge cut phase dimming mode of SCR. A dimming master can be connected with two dimming slaves, each
output can be independently switching and dimming, and the max. Power is 1000W for per output. The load types
are similar to universal dimmers. Which make up the universal dimmer lacking in high-power lamps dimming
area.
The Triac dimmers take the leading edge cut phase dimming mode, which have 2-channels and 4-channels.
And max. power of each channel is 300W. It is mainly used to control some low-power dimmable lamps. Each
channel can be independently dimmed and switched.
The Dimmer is a modular installation device for fixed installation in dry rooms. It fits on35mm DIN rails in
power distribution boards or closed compact boxes. It can be programmed; it can be used to customize the rooms’
