The revolutionary charge and discharge circuits of the WR50 give you the power to measure resistance of highest Inductivities in shortest time. Including the world unique demagnetizing function, a simple 1 Button Core Demagnetization feature that can be used following a DC Winding Resistance test, or at any time. Core Demagnetization should be performed before an Excitation Test, an FRA measurement, or before any transformer is put into service.
 

• Simple touch screen operation.
• Core Demagnetization.
• Charges inductive loads up to 1500 Henry.
• Heavy duty protective circuitry.
• Fully remote operation capability with an external PC.
• 3 Temperature input channels.
• High power DC Supply (50V/50A).
• DC Current adjustable for resistance from 0.05µΩ to 100kΩ.
• Data transfer to internal/external printer at selectable intervals.
• Fastest discharge unit on the market.
• Visible and audible indicator for discharge status.
• Emergency discharge activates from emergency stop button or system power failure.
• Data storage of up to unlimited measurements.
• Built-in panel-mount printer.
• Mounted in rugged case for field testing.
• 5-year standard warranty.
