Product Description:
The B161S regenerative DC drive is manufactured by Danaher as part of the Quadraline Regenerative Drives series. The product functions as a four-quadrant speed controller for permanent-magnet or shunt-wound DC motors, allowing energy generated by overhauling loads to be returned to the line supply. In automated conveyors, test rigs, and web-handling lines, the drive modulates armature voltage and current to match command references while eliminating the need for mechanical reversing contactors.
It accepts a single-phase supply of 115/230 VAC with a tolerance of ±10% at 50 or 60 Hz and converts it to controlled DC power for the motor armature. The input line passes through a fuse and bridge before the power section delivers up to 10 A DC, matching the continuous current capability of the chassis. When powered from a 115 V line, the unit supports motors rated up to 1 HP and provides an armature output of 90 VDC. When powered from a 230 V line, the unit supports motors rated up to 2 HP and provides an armature output of 180 VDC. These ratings allow one model to operate low- and medium-power axes without changes to the drive hardware. Its continuous-duty design supports sustained load profiles when the unit is installed with adequate ventilation and operated within the permitted temperature range.
For closed-loop accuracy, armature feedback is maintained within ±2%, and a tachogenerator port accepts a 12.25 VDC signal to monitor shaft speed. The drive can regulate motor speed across an armature feedback range of 30:1, while an external tachogenerator permits a wider 50:1 range for applications that must maintain control at low and high speeds. Operation is permitted at chassis temperatures up to 55 °C; above this temperature, the controller must be derated or provided with additional cooling. The chassis-mount format allows the drive to be attached directly to a panel. Wiring requires two line conductors and a protective earth connection, which simplifies integration into a compatible single-phase electrical system.
