TCM link capacitors are used in conjunction with Bosch Rexroth Indramat power supplies. TCM drives are used to reduce or eliminate the noise created by the mains line. Noise is usually created in excess when circuit power exceeds 15kW. TCM drives are connected at different points along the mains line and are subjective to the layout of the wiring and the length of the mains line. These drives weigh approximately 6 to 7 kg. These link capacitors are commonly used with “K” series Indramat Rexroth power supplies such as KVR or KDV power supplies. They are a common piece found in automation control lines.
