Dimmer

Â

Function:

Â

• Â Intended use
• Â Switching and dimming incandescen lamps,HV halogen lamps and Tronic transformers with halogen lamps
• Â Suitable for mixed operaion up to the specified output(see section Technical data)
• Â Installation in applicance box to DIN49073
• Â No operation with inductive transforers

Â

Product characteristics

Â

• Dimming principle: Trailing edge se cut-off
• Built in press on/off and rotary knob dimming control
• No neutral required
• Minimum brightness adjustable with MIN knob
• Electronic short-circuit protection with permanent switch-off after 7 seconds at the latest
• Electronic over-temperature protection 120 degree off,automatically open below 120 degree .
• Changeover swithcing possible in combination with changeover switch
• Power extension through power boosters (see power booster instructions)
• Flickering of the connected lamps due to undershoot of the specified minimum load or through centralised pulses from the power stations. This does not represent any defect in the device.

b. mount the frame and the central plate.

c.attach the adjusting knob

Â

Instruction manual for useÂ

Â

Step 1Â Switch on/off lightÂ

Â

· Press the control button to switch on or off the light

Â

Step 2 Adjusting the brightness

Â

· Turn the control button in the clockwide direction ,the light gets brighter p to maximum brightness

· turn the control button in the anti-clockwise direction , the lights will gets darker to minimum brightness

· Turn the MIN knob in the anti-clockwise direction to obtain expected bottom brightnessÂ

Â

Troubleshooting

Â

• · The dimmer switches the load off and only on again after some timeÂ

• · Overheating protectin has tripped.

• · Reduce the connected load.

• · Check the installation situation

• · The dimmer switches the load off briefly and then on again.

• · Short-circuit protection has tripped but now there is no longger a fault.

• · The dimmer switchs the load off and cannot be switched on again.

• · Short-circuit protection has tripped.

• · Eliminate short-circuit.

• · Switch the dimmer back on by pressing the control knob twice.

• · Short-circuit proteciton is not based on a conbentional fuse,no metallic separation of the operational current.

FAQ :

Â

1. Why Trailing edge dimmer ?

Â

Trailing edge dimmers are Reverse se dimmers.  They are more sosticated than cheap leading-edge dimmers.

Â

On sale, the trailing edge dimmers use a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) switch rather than a TRIAC and coil.

Â

This benefits the user with smooth, silent dimming control, absent of any buzzing noise.

Â

A trailing-edge dimmer has a lower minimum load than leading-edge dimmers, making it a better choice for dimming modestly sized low-powered lighting circuits.

Â

Particularly beneficial for incandescent and halogen bulbs is the ‘soft start’ feature in trailing-edge dimmers, which prevents filament bulbs from dying or exploding of thermal shock when first switched on.

Â

2. what brands of dimmers your triac driver can work with ? Can your drivers with both leading edge dimmer and trailing edge dimmer ?Â

Â

We can guarantee above 90% brands dimmers in the world our driver can work with like below：lips, STM,Onsemi,Teccor,Renesas,NEC,Toshiba,Sanken, and yes ,our drivers can work with both dimmers.Â

Â

3. How many years warranty ,and if there is defective drivers ,what will you do ?Â

Â

a. We give 3 years warranty ,we will 100% quality check for every product before we deliver .

Â

b. if there is any defective drivers happened , we will check together with you  if it is the n issue or the dimmer compatitable issue ,after that if we found there is still problem maybe caused by transport or condition or someother reason ,we will send you a new one for replacement. Â

Â

4. What certificate do you have ,can you send us by the test report ?Â

Â

For now ,we have got CE-EMC certificate ,CE-LVD certificate issued by Intertek lab. And we can send you our test report if you ask for it .

Â

5. Do you have service of ODM /OEM?

Â

Yes we do.

Â

6. Can you help us to make special drivers according to our specific request ?Â

Â

Yes, we have a team for desinging the all kind of drivers, if you need, please tell us ,but we need you pay the design cost firstly ,but we will pay back if you send us order over 10000 pcs .

Â

7. Do you have distributor in our local market ?Â

Â

No, but we are very pleased if there is partner in your local place , but we need the partner who has professional skill to sell and make maintance of our products .
