Max. 2 Red 30mA 2.0V 2.8V DC4V 5 Green 25mA 2.1V 2.8V DC4V 8 Yellow 30mA 2.2V 2.8V DC4V Current to be applied to the LED must be lower than the forward current (IF) indicated in the LED Specifications of each switches. Resistance value R should be calculated using the following formula. ●Case of static lighting system. ●Case of dynamic lighting system. ●When LEDs are used by a pulse lighting system ●Calculation Example Pw Dr IFM E VF : 0.1 msec. : 1/10 : 50mA(All colors) : 5V : 2V R = = 60 (Ω) 5 − 2 0.05 R = E − VF IF R = E − VF IFM |
