Three-phase current transformer with attached rectifier DG
Technical Information:
The DG series is characterized by its robust and simple
design. For you this means a reliable and at the same time inexpensive power supply from standard parts. The elongated design of the DG series requires a small footprint in your switch cabinet. Due to the low installation depth, the devices can be optimally installed between the cable ducts.The DG series is designed in such a way that the rectifier plates with the press-fit diodes are always optimally located in the cooling current when mounted on the floor or wall.
Basis of the rectifier device is a three-phase current
transformer with separate windings according to EN 61558-2-6
with double insulation and increased air and creepage distances.Transformers are vacuum impregnated with cast resin varnish to reduce humming noise and increase insulation.Low switch-on rush of the transformer and therefore suitable for the use of inductive motor protection switches.
terminal connection with generously dimensioned
cross-section to reduce the voltage drop and
according to VBG4.
three-phase bridge rectification with protective circuit
by varistor. No-load
voltage.
residual ripple at rated current less than 4.9%. Screening on
request possible at extra charge.
The 3.5A - 10A power supplies can be supplied at low
extra charge with snap-on mountings for DIN top hat rail
.All power supplies are dimensioned by computer, with
CNC machines manufactured, piece-tested including a
high-voltage insulation test according to VDE. CE-compliant; protection class IP00, installation up to IP21

Our company has 3 production sites in Germany. WOLTERSDORF Schweißmaschinen develops and produces MIG/MAG equipment and systems, TIG welding systems, plasma welding equipment (PTA) and welding rectifiers in the power range from 200 to 800Aselbst. Since its establishment, continuous development and economic independence have been emphasized.
Today we have a complete range of welding equipment and machines and sell them in Germany and in export to 30 countries worldwide.
Besides MIG/MAG machines, we also supply pulse welding equipment, TIG welding inverters (DC and AC/DC) and electrode welding inverters. An extra section of WOLTERSDORF Welding Machines is the development and production of special test and measuring equipment, such as mobile calibration validation devices for welding systems up to 1400A.
Special solutions like MIG 41 Push-Pull for shipbuilding and the CARMIG series for automotive complete our product range.
All our equipment is tested under the toughest conditions prior to series production and constantly subjected to strict controls during manufacture. This gives us the security and you the guarantee to always receive a fully developed product. Exports are handled exclusively by our distributors.
In the interest of technical development, we reserve the right to make changes in design and construction.
