8. ON/OFF & Description of Dimming Operation

A. Short-press the PUSH switch (short-press time 0.1s-1s), the LED driver will turn on or off.

B. Dimming: Press and hold the PUSH switch (1s-8s), the LED driver can achieve dimming, brightening, or dimming, the dimming range is 2-100%.

C. Memory: PUSH dimming has a dimming memory function.

D. Dimming synchronization: The power connected to the same PUSH switch can be synchronized by pressing and holding the PUSH switch for longer than 15 seconds.

E. DALI dimming mode: Connect the power supply to the DALI system, and it can be dimmed by the DALI host. The dimming range is 0-100%.

9. Matters needing Attention

1) The LED string must be connected to the load before turning on the input power; otherwise, the LED string may be damaged.

2) After the LED drive input is powered off, there will be a residual voltage at the output, which can be maintained for about 3 minutes.

3) Before setting the parameters by NFC, please make sure the driver is powered off.

Focus on intelligent lighting control and innovate constantly！

Core Technologies Advantages

Microwave Motion Sensor

Based on principle of Doppler effect and 5.8GHz microwave detection technology for motion detecting. Currently, Merrytek developed over 200 models motion sensors which support long detection area up to 20m, 15m mounting height and outdoor use motion sensors. Those are at the leading position in our industry.

Typical products: MC and MLC series.

LifeBeing Presence Sensor Technology

As only support big range movement detecting, microwave is normally used in the places people only make a brief stay, for example, corridor, stair well, warehouse and parking lot. Merrytek use high frequency microwave and unique programming, microwave sensors are able to detect very minor movements, i.e. typing and breathing to avoid false reporting and underreporting. Merrytek provides series sensors with KNX, DALI, 485 and Bluetooth for building automation.

Application: office, classroom, meeting room, kitchen, rest room and so on.

Typical products: MSA series.

Daylight Sensor

As always, Merrytek concentrates on simple intelligent light solutions and luminaries’ construction. We successfully completed an in depth study of our patented self-adaptive LED drivers which can identify artificial light and natural light. We therefore can supply an extremely cost-effective and energy saving daylight harvesting solution for office use.

Typical products: MS series

Flicker-free DALI/1-10V Dimmable LED Driver

Replacing traditional incandescent and fluorescent lights with more efficient and longer-lasting LED-based solid-state lighting (SSL) is an undeniable trend in the lighting industry. However, since SSL fixtures are directly connected to an AC power supply, (consistent with legacy lighting), there is a risk that 100-Hz or 120-Hz flicker could occur as a result of the driving AC current’s fluctuation at the supply's output. Flicker can make people uncomfortable, causing headaches, stress and fatigue even though the human eye may not detect the flicker.

Currently, most of dimmable LED drivers have flickering issues (especially PWM types), when dimmed below 5%. Merrytek newly-developed flicker-free dimming technology can eliminate nearly all flickering and even when dimmed to 2%.

Typical products: ML and KL series.

Emergency Pack for LED Lighting

From 2016, Merrytek has dedicated to quality emergency pack for LED fittings, such as ceiling lights, tri-proof lights, down lights and panel lights. Top quality battery will be use in all our range and make sure excellent life time and good reputation.

Typical products: KE and ME series.
