These are fully refurbished Syntron Magnetic Feeder F-010-B with a Vibratory Controller / Rectifier in excellent condition.  The Controller has been tested with US 115VAC and 230VAC Single Phase, and the system works great with either voltage.  Per manufacturers' Service Instruction guides, these devices are rated at Maximum Current Rating: 2.0 amps 115V/50-60 Hz or (nameplate) 1.0 amps 230V/50-60 Hz.

With 115VAC, the intensity is not as strong on the vibratory device compared to 230VAC, but this can be compensated by moving the internal magnet assembly closer to the rear of the device plate which is easily done in a few minutes time, and instructions are provided in manufacturer Service Instruction guides available online.

The device will ship WITHOUT an AC Power plug on the end of the controller.  You should install the proper 110VAC or 230VAC or hardwired connection per your installation requirements.  (115VAC USA plug shown for demonstration only)

The provided Controller has 3 simple to utilize controls (Sorry about the non-English labeling)
