The SR2303AC4CHDIN from Sunricher is a Four Channel, DALI DT6 Phase Cut Dimmer and for ease of installation, the dimmer is DIN Rail mountable. This feature rich product will control your mains powered, single colour lighting products with both a resistive and a capacitive load enabling it to be used with mains powered LED Lighting, LED Drivers, incandescent lamps and low voltage halogen lamps with electronic transformers. The dimmer can be set as 1, 2, 3, or 4 channels so that it can control all the channels simultaneously or separately.

The dimmer supports DALI DT6 protocols and is compliant with all DALI 2 products on the market, the DALI address can be set manually using the menu buttons and digital display or automatically from the DALI Master. The unit supports an input voltage of 100v - 240v AC and it also has a "Push Dim" facility. The factory-set dimming level is from 1% up to 100% however, the minimum brightness level can be set as required to accommodate lamps that flicker when dimmed too low. Once the minimum brightness has been set, the unit will not dim any lower that that value on all four channels.

Note: This unit is a Reverse Phase (trailing edge) dimmer so it is important to check that the products that the dimmer is controlling support Reverse Phase Dimming.
