Voltage 460VAC, 60HZ, 3 phase 200 Amps, Four - No. 4 AWG 3.1.2 Performance Characteristics Magnetizing Output Current (maximum): 6000 DC Control Setting: Infinite adjustment. Regulation: Electronic Rectification: Silicon Controlled Rectifiers (SCRs) Demagnetization Output DC Mode: 6,000 amperes (maximum) alternating polarity ramped to zero amperes Range of Automatic Timer DC Magnetization: 1/6 to 1� seconds (� second normal) DC Demagnetization: 15 to 40 seconds (30 seconds normal) Manual Timing: Manual operation (Remote cable must be used for manual timing) (Terminal cutout will disconnect unit if overheated.) Duty Cycle At 100% Rated Output: .5 seconds ON, 4 minutes OFF At 40% Rated Output: 10 seconds ON, 3 minutes OFF Thermal Cut Out: Disconnects unit if overheated Convenience Outlet: 115V AC, 60 Hz, 5 amperes Weight: 1150 pounds (approximate) Dimensions (Overall) Length: 136 inches Width: 111 inches Height: 112 inches 3.1.2 Detail Description 1. Constructed of a rigid steel framework with full louvered panel finish. 2. Maximum current output is 6,000 amperes FWDC in the conventional mode. 3. Complete with automatic reversing DC demagnetization. 4. Complete with (quick break) circuitry to ensure maximum residual field and maximum repeatability of inspection results. 5. Complete electronic controls including self-indicating plug-in modules for reliability and ease of maintenance. The electronic controls also provide a very fast response time of only 8 milliseconds, i.e. time taken for the magnetizing current to reach the desired level.6. Complete with infinitely variable, current control current selection between zero an…
