For input voltages up to 40 VDC (28 VAC)
PREMA IC PR4101
Among others, the PR4101 is for applying LED lamps in 12 / 24 V grids for retrofit applications. Based on additional electrical components, single or multiple LEDs can be operated with currents from 100 mA up to several amps. Efficiencies > 90 % are obtained when the IC is applied properly. Individually, the LED current can be selected by a low ohm resistance (< 1 Ω).
Beside a variety of shutoff functions as LED or IC overheating, a unique selling point is given by a low standby current of less than 35 µA. PWM dimming as well as softstart are some of the properties that can be used based on additional electrical components.
