Dimmable multi-current LED driver -- HE1050-A

LED current selection: 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.)

Extended RF dimming function: 
An extended interface to our 1-10v dimming terminal. This extended dimming function is very convenient for RF and Zigbee dimming with external RF or Zigbeem odule. The external RF/Zigbee module is an user friendly design: Plug and Play. 

PWM dimming: 
PWM dimming is available upon customer's request, it is easily and quickly achievable by minor adjustment on the PCB layout and output terminal. 

Switch-Dim:

•  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.
