2 x 25W IP20 Dimmable LED Driver 250mA - 700mA For LED Down Light

Description:

1, Two output channels for different applications. Use DIP switch for output current setting, each channel supplies selectable current from 250mA to 700mA.

2, Built-in PUSH and 1-10V dimming interface, offer smooth dimming range from 0%-100%.

3, Jumper design for switching different dimming modes, it is very convenient to select suitable dimming function as you required.

4, Memory function: The driver has built-in permanent memory against power failure. Lights can return to previous dimming level when switch off and on again, even at mains restores.

5, Synchronization: thanks to the MCU programme, up to 50pcs drivers should be controlled by the same switch. This means there is no need for any additional synchrony wire in larger installations, where many drivers should be controlled by one switch.

6, Maximum length of the cable, from switch to last driver is 20m.

7, Factory setting: 100% dimming level and 250mA output.

8, Reset the LED diver easily by a jumper.

9, Press-in terminals in primary and secondary side, easy assembly.

10, Protection: Short circuit / Over voltage / Over temperature.

11, Long life span 50,000h, 5 years guaranty.

Applications:

For LED down light, LED panel light, etc…

Dimming Operation:

A) PUSH Dim

Short push (<0.1sec): Ignore, to avoid reaction on AC spike.

Short push (0.1~1sec): Switch on or switch off.

Long push (>1sec): Dimming up or down, dimming level automatically stops at minimum or maximum value.

B) 1-10V Dim

Using the push dimming will make 1-10V dimming inactivated. The driver has to be reset to active the 1-10V dimming function again.

Synchronization:

For the resynchronization to work correctly when more than one driver is connected to the same push button, follow steps of below after the drivers are connected:

A) Press push button for more than one second, followed by a short push (<1s), now, led light switches off.

B) Do a long push, the system will be resynchronized.

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.
