DIMMING OPERATION
120W Single Output LED Driver
NPF-120D series
NPF-120D
** For wire diameters,
please refer to
Mechanical Specification
※ Auxiliary DC operation (for BE-type)
‧ AUX+, with mark ***, is added for BE-Type, used as the Auxiliary DC output with respect to DIM-.
※ 3 in 1 dimming function
‧Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
0 ~ 10VDC, or 10V PWM signal or resistance.
‧Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers.
‧Dimming source current from power supply: 100 A (typ.)μ
◎ Applying additive 0 ~ 10VDC
◎ Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz):
◎ Applying additive resistance:

Dimming input: Additive resistance
Note : 1. Min. dimming level is about 6% and the output current is not defined when 0%< Iout<6%.
2. The output current could drop down to 0% when dimming input is about 0kΩ or 0Vdc, or 10V PWM signal with 0% duty cycle.
