High current transformer up to 65000A (HGV 70 – 300kVA / up to 60kA IEC/DIN EN 61558-2-6)3AC-400V Isolating Transformer, watercooled version High Amperage DC Power Supply

overviewtechnical dataPDF data sheet

Typical applications

High amperage DC power supply suitable for 3 – 6 VDC output voltages and approx. 80 kA.Input circuit: Thyristor control and primary circuit located taps.

HGV series is used in galvanisation and other high current typical applications and process engineering.

Specifications

  • Output voltage of 3 – 6 VDC can be adjusted in 0.5 V steps via primary circuit taps.
  • Screw terminals for primary circuit connection.
  • Standard input voltage: 3x 400 V at 50/60 Hz, customer specific adjustments on request.
  • Output voltage is rectified via double star switching matrix, low remaining alternation – approx. 4.2%.
  • Output connections: Customer specific solutions, e.g. massive copper bolts.
  • Number and design of cooling circuits as well as water pressure and water temperature depends on max. load and kind of operation – to be designed by Schmidbauer according to application.
  • HGV high amperage DC power supplies are constructed and built for permanent operation.
  • Temperature of diodes and transformer can be monitored and controlled separately (Standard: 2 monitoring circuits with automated temperature switches).
