THE INDUSTRIAL ACPL-K308U PHOTOVOLTAIC DRIVER IS DESIGNED TO DRIVE HIGH VOLTAGE MOSFETS

The industrial ACPL-K308U photovoltaic driver is designed to drive high voltage MOSFETs. It consists of an AlGaAs infrared light-emitting diode (LED) input stage optically coupled to an output detector circuit.

THE INDUSTRIAL ACPL-K308U PHOTOVOLTAIC DRIVER IS DESIGNED TO DRIVE HIGH VOLTAGE MOSFETS

The detector consists of a high-speed photovoltaic diode array and a turn-off circuit. This photovoltaic driver turns on (contact closes) with a minimum input current of 5 mA through the input LED. It turns off (contact opens) with an input voltage of 0.8 V or less. The ACPL-K308U is ideal for the fast turn ON/OFF in inrush current prevention and Insulation resistance measurement/leakage current detection.
