HMF01.1N-N0K1-M1190-N-690-NNNN

The Bosch Rexroth Indramat HMF01.1N-N0K1-M1190-N-690-NNNN from the HMF Motor Filters series is engineered to mitigate high-frequency voltages and transient overvoltages in servo motor systems. This Dv/dt Filter w/ Limiter features free installation design and operates at a supply voltage of 3 × 690 VAC to safeguard sensitive drive electronics. Boasting a rated current of 1190 A and delivering a rated power output of 1 kW, it effectively attenuates leakage currents and extends motor bearing life. Manufactured under stringent quality protocols by Bosch Rexroth Indramat, it complies with industrial demands for durability and performance.

Built for reliable operation in harsh environments, the filter tolerates ambient temperatures from –10 to +50 °C without derating and is rated for altitudes up to 1000 m above sea level. Its natural convection cooling dissipates heat into surrounding air, eliminating the need for auxiliary fans. To ensure proper ingress protection, the unit is designed for installation within a switch cabinet providing at least IP54 enclosure rating. With overall dimensions of 370 × 230 × 250 mm, the compact footprint facilitates integration into standard control panels and cabinets.

Maintenance requirements are minimized thanks to its robust construction and Bosch Rexroth Indramat’s one-year replacement warranty backed by global service support. Installation should be performed by qualified personnel in accordance with the manufacturer’s climatic and mounting specifications. When paired with compatible Rexroth Indramat drive controllers, the HMF01.1N-N0K1-M1190-N-690-NNNN filter ensures peak performance and reliability across a wide array of industrial automation applications.
