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

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
