Transient suppresion transformers

Electrostatically shielded transformers
Type SDT
Specially designed single-phase isolating transformers
with high transient suppression and low noise level.
Designed and tested according to norm EN61558-2-
19. SDT transformers are electrostatically shielded
and have output filters which protect systems from
unwanted ”noise” and highfrequency voltages that
can occur due to switching and loading on distri-
bution lines. Portable type, easy installation.
Applications:
Designed to protect equipment that requires a low-
noise voltage in order to work without problems
e.g.: computer equipment, telephone exchanges and
audio-equipment.
