This multi-current LED driver has covered the normal curren in the market. The current can be easily configured by choosing the correct combination of the DIP switches. Warning: please make sure the correct current is selected before switching on the driver!!! (Over-current may cause serious damage to the LED, while under-current does not give the full light output of the LED.)
- On/off: Short push(50-400ms) on the switch.
- Stepless dimming: Long push and hold ( > 400ms) on the switch.
- For fine tuning of light level: With every 2nd long push,the light level goes the opposite direction.
- Built in with permanent memory: Light returns to the previous dimming level when switched off and on again, even at power failure.
No limitation on the number of drivers when connected to the same switch, Thanks to the MCU program.This means there is no need for any additional synchrony wire in large installation, where many drivers should be controlled by 1 switch.
When users push the switch too fast and too often during a short period of time, the drivers may not output the same current, and the LED may have different brightness, in such case, we just need to- 1. short push to switch off the light, and then.. 2. a long push to start up the lighting, then all LED will be synchronized and stays in the same brightness. This driver can also be reset by short-circuit the 1-10v terminals.
This driver has buit-in permanent memory against power failure, the light always start up at the previous level when they were switched off last time.
