Shunt Regulator: 26.4V, 4.00Ohm, 9W

This shunt regulator can protect power supplies from voltage spikes generated by motor controllers they are connected to. This version has a fixed set point of 26.4 V, a shunt resistance of 4.00 ohms, and twelve SMT shunt resistors populated on one side of the PCB (this is the lower-power version). An external potentiometer can also be added to change the set voltage.

Specifications:

• Output voltage: 33.0 V
• Shunt resistance: 4.00 Ohm
• Power: 9 W
• Maximum quiescent current: 0.5 mA
