1-10V VS Triac

A range of our luminaires can be used with a choice of dimmable drivers. Below is an explanation of the differences between the 

most common types of dimming controls 1-10v & Triac to help you choose the option that best suits your requirements.

Dimming with 1-10V control system

These modern dimmers with 1-10V interfaces in connection with the relevant sensors and control elements offer the prerequisites 

for inexpensive and simple lighting projects. They were able to successfully establish themselves as the standard for 

uncomplicated lighting solutions. The control unit and the ballasts are connected to one another via a two-core, polarized control 

line. The respective control voltage determines the dimming position of the connected power supply units.

The intensity of the emitted light of all dimmable lights can be controlled from 0 to 100 percent, which accept 1-10 volt LED 

dimmer solutions. It supports a load of around 200 watts.

1-10V interface, the characteristics:

Power supplies can be dimmed at different phases by the same control device.

Control via fail-safe 10 volt DC voltage signal (open control line, maximum brightness) up to 1 volt (short-circuited control 

line, minimum brightness).

The control line voltage is potentially isolated from the power line, but not a safety extra-low voltage (SELV).

The active power supply units 1-10V generate the control power of 0.6 milliamps per power supply unit.

Inactive power supply units 0-10V wait for an incoming control power. The maximum current is 0,6 milliamps.

It must be possible for the connected control unit to absorb the current that is supplied by the power supply units into the 

control line and to reduce the control voltage.

Over longer distances, such as streets or halls, it can happen that different control voltages arrive at the lights due to line 

resistance, which leads to different dimming of the lights.

TRIAC Dimming

Mechanical dimming system

Adjusts brightness of light by varying the voltage supplied to the lamp

Used for simple smooth dimming functionality

Inexpensive to implement

Low maintenance and long lasting

LED Tubes can be made with TRIAC capabilities built into the tube, upon request

Installation process remains unchanged when installing dimmable LED tubes
