The Pololu 33.0V, 4.10 ohm, 15W Shunt Reg is an electronic component that functions as a low-voltage differential amplifier with low power and low operating temperature. It is designed to protect delicate equipment from over-voltage, short-circuits, and high temperatures. The Shunt Reg produces a steady voltage output, which is unaffected by the voltage and current input to the circuit. The part features a single-channel, high-current output and a specified continuous range from 0.0 to 33.0V. Its maximum wattage capacity is 15W, while the nominal resistance is 4.10 ohms. The temperature range of operation is -40°C to +85°C.
