The non-PWM LED dimmer was developed for absolutely flicker-free dimming of constant current-controlled LEDs or LED lights. It dims absolutely without pulse width modulation and is a purely linear dimmer. It is possible to perfectly control the brightness of the LEDs between 0% and 100% with a dimming resolution of 19 bits (internal resolution). The LED dimmer can be set from speed calculation to absolute time calculation by parameterising each channel. This makes it easy to realise all conceivable control tasks.
Depending on the configuration and LED type, this dimmer can control LEDs with a total output of up to 300W (4x 75W).
Channel coupling is possible for LEDs with higher currents. When coupling, the physical outputs can be defined as main current and precision current. For the output with the precision current definition, we recommend calibrating a lower current (e.g. 300mA). This allows the dimmer to be dimmed up very sensitively from the lowest dimming range, especially for LEDs with high currents (e.g. 2500mA).
We recommend this dimmer for all areas and applications where perfect dimming down to the minimum and - thanks to analogue dimming - healthy and camera-compatible dimming of the lighting is important.
Application areas:
- Planetarium
- Theatre
- Museum, gallery, exhibition
- Clinic and nursing home
- Office and other workplaces
- School and educational institution
- Hotel and conference room
- Shopping mall and retail shop
The LED dimmer can be operated with either the ISYGLT, DMX512 8/16 bit, DMX-RDM 8/16 bit or DALI protocols.
