Regulated current source has resistance, optical coupler, diode current path, voltage-limiter, regulator with controllable semiconducting switch, Schottky diode to reduce diode flow voltage
Regulated current source has resistance, optical coupler, diode current path, voltage-limiter, regulator with controllable semiconducting switch, Schottky diode to reduce diode flow voltage
The current source has a resistance (R1), an optical coupler (OK1), a diode current path, a voltage-limiting component (D2) and a regulating unit containing a controllable semiconducting switch. A Schottky diode (D3) is used to reduce the flow voltage for the diode.
