Bardac 3600XRi DC Motor Controller

The Bardac 3600XRi DC Motor Controller is a compact, single‑phase regenerative DC drive with reversing and fully isolated control that delivers precise torque and speed control for DC motors. It accepts 120 VAC or 230 VAC input on a single phase and provides armature voltages of 90 VDC or 180 VDC, with a maximum armature current of 32 A and a 2 A field current limit, enabling about 3 HP at 120 V input and 6 HP at 240 V input. The 3600XRi/32 variant is housed in an open‑chassis enclosure measuring roughly 7.87 in wide by 6.89 in high and 2.76 in deep, weighing about 3.5 lb, and features isolated control electronics for safe installation. For control flexibility, the drive supports closed‑loop operation using either armature voltage or a shaft tachometer as feedback, offers adjustable current and speed limits, and accepts diverse speed‑demand inputs (potentiometer, 0–10 V, 0–20 mA, or 4–20 mA) with stall protection and regenerative braking to recover energy during deceleration.
