SR-2318B DALI 4-channel LED dimmer CC 12-36 V DC 700 mA DT6

Sunricher SR-2318B is a professional four-channel DALI LED dimmer with constant output current (CC), designed to regulate the intensity of LED modules with working current 700 mA.

The device supports DALI-2 DT6 and allows joint or independent control of four output channels. It is suitable for residential, commercial and intelligent electrical installations, in which precise and reliable control of LED lighting is required.

The dimmer works with the input voltage 12–36 V DC and provides four constant current output channels 700 mA per channel. It reaches the maximum total output power 33.6 W at 12 V DC, 67.2 W at 24 V DC or 100.8 W at 36 V DC. An external DC power supply is required for operation.

Flexible DALI addressing

SR-2318B allows setting 1 to 4 DALI addresses, thanks to which the individual output channels can be controlled together or independently.

When using one DALI address, all four channels are controlled synchronously. When setting four addresses, each channel can be dimmed separately. This solution is suitable for controlling several light circuits from one device.

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

Dimmer allows continuous regulation of lighting intensity in the range of 0.1–100% with a logarithmic dimming characteristic.

DALI and Push DIM control

In addition to control via the DALI bus, the SR-2318B also supports a function Push DIM, which enables lighting to be switched on, off and dimmed using a classic button without the need for a DALI control unit.

A short press of the button switches the lighting on or off, a long press changes the light intensity. When held down again, the dimming direction is reversed.

The device can be integrated into the KNX system via a compatible KNX DALI gateway. It is also suitable for separate DALI lighting systems.
