Shunt Regulator: Fine-Adjust HV, 4.10 Ohm, 15W LCD Display as shown in the motorThis shunt regulator can protect power supplies from voltage spikes generated by motor controllers they are connected to. This version has a precision adjustable set point (4 V to 35 V), a shunt resistance of 4. 10 ohms, and a total of 32 SMT shunt resistors populated on both sides of the PCB. Specifications: Minimum output voltage: 4 V Maximum output voltage: 35 V Shunt resistance: 4. 10 Ohm Power: 15 W Maximum quiescent current: 0. 5 mA
