AMC's shunt regulators solve transient over voltage problems quickly clamping regeneration voltage to safe levels. These simple devices can increase system reliability by stabilizing voltage fluctuations and eliminate over-voltage shutdowns.

A shunt regulator "clamps" the power supply voltage to a set level and prevents unexpected shutdown or damage. It monitors the power supply voltage and if the voltage exceeds the set limit, the shunt regulator "bleeds off" the extra voltage through a power resistor. The shunt regulator is only active when the voltage exceeds the set level, otherwise no current passes through the power resistor. The shunt regulator automatically turns the power resistor on and off as necessary to regulate the voltage, sometimes up to several hundred Hertz.
