R911335903
The R911335903 (HNL01.2E-0400-N0051-A-480-NNNN), made by Bosch Rexroth Indramat, is a valuable tool when working with parallel connected transducers in close proximity. This main choke is particularly useful in attenuating capacitor overloads for cosine correction. It's essential that only qualified personnel handle the product installation, ensuring the power supply is disconnected before making connections. This high-quality product, with a rated current of 51A, also boasts a low-temperature rise and effective defense against voltage dips in the main voltage due to commutation. The product is equipped for single-conductor, unshielded wiring.
This technical piece contains three inductors with a 400µH inductance and operates at a frequency of 50/60Hz. Its function is not only to limit main disturbances like voltage spikes but also provides overvoltage protection. The mains choke can be used if numerous inverters are connected with a single cable, supporting operation of a regenerative supply unit at the mains. The choke, weighing at 13.5kg, can be mounted in any orientation, and its ground terminal connection screws (U1, V1, and W1) are of size M6. The device simultaneously cuts down line current harmonics, reducing system disruptions while maintaining device integrity. The R911335903 (HNL01.2E-0400-N0051-A-480-NNNN) accepts a mains connection voltage of 3 x 400 to 480VAC, with a tolerance of -15/10%.
