28W 350~700mA*2ch DALI DC-DC CC Driver BMP28D-2SMC-S
BMP28D-2SMC-S is a DC/DC constant current output LED driver.The output current can be set via DIP switch.It can be controlled by DALI master, and the dimming curve is smooth and flicker free.


· Output current 350-700mA, can be set via DIP switch
· Compliant with DALI 2.0 standard protocol
· Mixed dimming PWM+CCR, no flicker
· Short circuit protection, overload protection,no load protection,Input reverse connection
· Built-in driver
· Hot plug for input port and non polarized

No-load operation The led driver will not be damaged in no-load operation
Short circuit Shut down the output self-recovery after removing the fault
Over load When the output voltage is exceeded, the output current decreases and, recovers automatically when the load is reduced.
Input reverse connection Operation normally
Hot plug Input Support
