Remarks
1. It is recommended that customer should install over voltage and under voltage
protection devices and surge protection devices in the power supply circuits of the
light fixtures to ensure safety before connecting to electricity.
2. The LED driver used in combination with the end device is one of the accessories of
the whole light fixture, and the EMC of the whole light fixture is not only susceptible to
the driver itself, but to the LED light fixture and the whole light fixture's wiring. Thus,
the manufacturer of LED light fixture should re-confirm the EMC of the whole light
fixture before the whole light fixture is finished.
3. The test conditions of the circuit breaker configuration quantity are the same as that of
the inrush current test.
4. Unless otherwise stated, the parameters above are test results under the conditions of
ambient temperature of 25℃, humidity of 50%, DALI signal input, 100% load,
maximum output current, CCT of 3115K and input voltage of 230Vac.

Wiring Diagram of PUSH CCT Change
In PUSH dimming mode, continuously click twice (the time of each click is not less than 100ms, and the
interval of two clicks is not more than 200ms) to enable the switch between dimmable and tunable white
functions.
The PUSH dimming mode has the memory function in case of any power failure. Power on the driver again
and the light will return to the state before the power failure.

Wiring Diagram of PUSH Synchronous Dimming For Multiple Drivers
Connect the PUSH signals of multiple drivers together.
Connect these PUSH dimming signals to wire L via PUSH button.
PUSH Dimming Operation Instructions
The PUSH operation won’t cause any variations if it’s less than 0.1 sec
Minimum dimming depth of PUSH dimming: 5% (Iout)
Default output state when entering into the PUSH mode for the first time: dimming (100% brightness; two-
channel output with 50% warm light and 50% cold light)
For the first long press on the PUSH button, the CCT (warm light and cold light) remains unchanged and
the brightness decreases.
The present PUSH dimming direction is opposite to the former one.

PUSH CCT Change Operation Instructions
The PUSH operation won’t cause any variations if it’s less than 0.1 sec
Minimum CCT of PUSH dimming: warm light; maximum: cold light.
Default output state when entering into the PUSH CCT change mode for the first time: two-channel output
with 50% warm light and 50% cold light.
For the first long press on the PUSH button, the brightness remains unchanged and the CCT change
adjusts to the cold light.
The present direction of PUSH CCT change is opposite to the former one.
DALI Dimming Operation Instructions
Factory default settings: two-channel output with 50% warm light and 50% cold light; 100% brightness
Connect the DALI signal to the DA1 and DA2 terminals.
DALI protocol includes 16 groups and 64 IP addresses.
Minimum dimming depth of DALI dimming: 5% (Iout).

Instructions on Switch of Dimming Modes
When powering the driver on for the first time, the driver enters into DALI mode; 100% brightness; two-
channel output with 50% warm light and 50% cold light.
The switch between DALI and PUSH modes:
1．Switch to PUSH mode: long press on the PUSH button for more than 0.6 sec; the present output state is
the former one memorized by PUSH mode.
2．Switch to DALI mode: the moment the driver receives any DALI instructions; for non-dimmable instructions,
the present output state remains unchanged; for dimmable instructions, the driver dims up and down.
