Product Description:

The 19.R6.N1E-900A is a regenerative line drive manufactured by KEB and supplied under the R6 Combivert Line Regen Drives series. The unit connects to a common DC bus and channels surplus braking energy back to the three-phase mains. This regenerative function helps induction-motor systems meet energy-efficiency targets while reducing the required size of external braking resistors in industrial automation cells.

The drive accepts an AC supply range of 180–528 V and operates at a line frequency of 50/60 Hz with a tolerance of ±2 Hz, allowing use on global distribution networks without transformer adaptation. During nominal operation, the input draws 70 A AC, while the DC link can conduct up to 80 A DC toward the utility. When used with multiple inverters, the module provides a continuous apparent power of 45 kVA, supporting medium-frame servo or spindle groups. A standard heat sink on the size E housing removes conversion losses. The default 1N.R6 (NCM) control platform performs synchronization checks, records faults, and controls the switching of the internal IGBTs.

Power loss reaches 470 W at rated load, and the aluminum heat sink may reach 88 °C before derating begins. Upstream protection uses a UL 248 Class J fuse rated at 90 A, helping prevent conductor damage during short-circuit events. The converter can handle peak regenerative power of up to 63 kW. Steady production lines typically operate near the 42 kW active rating or the 67.5 kVA apparent power limit, depending on the bus voltage. Unit size 19 establishes the required cabinet space, while a built-in precharging option gradually energizes the DC link to protect capacitors and limit inrush current. Its regenerative current capacity is 65 A AC, supporting dynamic deceleration cycles without external dump circuits.
