LDM-PH, a photo sensor for LDM, is connected to LDM module to sense the illuminance and transmit it to LDM (LED DALI Dimming Module) for dimming control of the lighting fixture according to the illuminance.
In addition, the photo sensor can transmit the illuminance value to the upper software through the DALI communication network, enabling monitoring of the illuminance value even at the central monitoring device.

Sensor type: Photo Resistor Type
Photo detection sensor for LDM
Illuminance detection range: 5-2,000 Lux
Directly connected to LDM for individual control of LDM and up to 64 interconnected LDMs with one DALI master.
Enable/Disable selection for Photo Sensing

LDM-PH is a module that senses the illuminance value by connecting to the bottom of LDM and provides it to the upper control software through the DALI protocol.
It is connected to LDM and 5-pin cable and can be installed separately from LDM.
It can control individual LDMs or grouped DALI module lighting fixtures ON/OFF and dimming control according to the illuminance.
It can save energy by controlling dimming according to the illuminance.
