Constant Current Regulator & LED Driver45 V, 25 mA 10%
The solid state series of linear constant current regulators (CCRs)are Simple, Economical and Robust (SER) devices designed toprovide a cost effecTIve soluTIon for regulaTIng current in LEDs. TheSER series regulators are based on patent-pending Self-BiasedTransistor (SBT) technology and regulate current over a wide range ofvoltage. The series is designed with a negaTIve temperature coefficientto protect LEDs from thermal runaway at extreme voltage andoperating temperature.
