· Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-: 1~0VDC, 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: 100uA (typ.).
48P series possess superior working efficiency that up to 90%
Can be reached in field applications.
This series is able to work in Constant Current mode (a direct drive way) to drive the LEDs.
