Shunt Regulators for Brush/Brushless Amplifiers
The SRST Series shunt-regulator assemblies are designed to work with ADVANCED MOTION CONTROL'S four quadrant regenerative servo amplifiers. During braking most of the stored mechanical energy is fed back into the power supply, which charges the output capacitor to a higher voltage. If the charge reaches the amplifier's over-voltage shutdown point, motor control and braking will cease. To ensure smooth braking of large inertial loads the use of a shunt-regulator is recommended. Verify the need for a shunt regulator by operating the servo under the worst case braking condition. If the amplifier shuts off due to over-voltage (blinking red LED) a shunt regulator is necessary (typically during downward move or deceleration).
