Advance Motion Controls SRST380H Shunt Regulator

The Advance Motion Controls SRST380H Shunt Regulator clamps the DC bus to 380 VDC during regeneration or voltage fluctuations, protecting drive inputs and maintaining stable operation for four-quadrant servo amplifiers. As part of the SRST shunt regulator family, it features a built-in shunt regulator circuit with a dissipation capability of 190 W and a compact enclosure measuring 203.2 x 108.0 x 66.7 mm (8.00 x 4.25 x 2.63 in), weighing about 385 g. It is designed for use with 400-volt amplifiers and four-quadrant regenerative servo amplifiers, providing a dedicated path to dissipate regenerative energy and prevent bus overvoltage during braking or voltage spikes. Manufactured by ADVANCED Motion Controls, the SRST380H offers reliable high-voltage bus regulation essential for smooth, predictable performance in high-power servo systems.
