SR-2304B DALI 4-channel LED dimmer CV 12-48 V DC 5A DT6

Sunricher SR-2304B is a professional four-channel DALI LED dimmer with constant output voltage (CV), intended for intensity regulation of single-color LED strips and other LED lamps powered by constant voltage.

Dimmer supports DALI DT6 and allows independent or joint control of four output channels. It is suitable for residential, commercial and intelligent electrical installations, where reliable and precise control of LED lighting is required.

The device works with input voltage 12-48 V DC. It provides maximum output current when supplied with 12-36 V DC 5 A per channel, at 48 V DC maximum 2.5 A per channel. The total maximum power reaches 720 W at 36 V DC or 480 W at 48 V DC. An external constant voltage power supply is required for operation.

Flexible DALI addressing

SR-2304B allows you to set 1 to 4 DALI addresses according to the desired control method:

• 1 address: All four channels are controlled together.

• 2 addresses: Channels 1 and 3 use the first address, channels 2 and 4 the second address.

• 3 addresses: Channels 1 and 2 have separate addresses, channels 3 and 4 use a common address.

• 4 addresses: Each output channel has its own DALI address and can be controlled independently.

DALI addresses can be set manually using the integrated digital display and buttons or automatically via a compatible DALI control unit.

Dimmer offers continuous brightness control in the range of 0.1–100% with a logarithmic characteristic that ensures a natural perception of changes in lighting intensity.

In addition to DALI control, it also supports Push DIM, which allows lighting to be switched on, off and dimmed using a normal button without the need for a DALI control unit.

The SR-2304B can be integrated into an intelligent KNX system via a compatible KNX DALI gateway. Thanks to four output channels, it is also suitable for controlling several separate light circuits.
