• Model ESR-N102 rectifies an input from an AC power source to DC and outputs it to electromagnetic chucks and for demagnetization, the attenuating alternating output is operated manually. A rectifier is built in. • Model ESR-5A relays the DC output to electromagnetic chucks and for demagnetization, the attenuating alternating output is operated manually. A rectifier needs to be installed in the preceding stage.
• Turning the dial repeats reversal of the circuits and changing over of resistance values for easy demagnetization. • Thanks to the manual type, it can be applied to diversified workpieces for individual machining operations by simply turning the dial.
