5 / 5 page DLE Series LED Drivers Dim+ V+ V- DLE Dim- Connect a variable resistor between Dim+ and Dim-. The Dimmed output current can be determined using the equation: Where the value of R is between 10 k Ωand100kΩ.Thecorresponding range of output current is 10% to 100% A Pulse Width Modulated (PWM) signal with duty cycle DPWM can be applied between Dim+ and Dim-. The dimmed output current is given by: Where Dpwm is the % of duty cycle between 10% and 100%. The corresponding range of output current is 10% to 100%. PWM frequency should be in the range 0.5 kHz to 5 kHz The dimmed output current is given by: Where V is the value of control voltage in the range of 1.0 V to 10.0 VDC. The corresponding range of output current is 10% to 100%. Connect a variable voltage betwen Dim+ and Dim- Output Current Adjustment by Variable Resistor Output Current Adjustment by DC Voltage Output Current Adjustment by PWM Dimmed Current 100 k Maximum Current x R = Dimmed Current 10 k Maximum Current x V = = Dimmed Current Maximum Current x DPwm % (Dpwm = PWM duty cycle) V+ V- DLE Dim+ + Dim- DLE Dim- GND PWM 0 V 10 V Dim+ V+ V- 5 www.xppower.com 06 Feb 14 |
