Mains connection devices
Due to regulated current consumption, the TVD 1.3 supply module offers the
lowest possible mains loading without reactive current.
Current regulators in switched-mode power supply system cause mains
system perturbations, the level of which depend on existing system conditions,
i.e., short-circuit power or mains inductance, at the installation site.
To eliminate mains perturbance, the TVD 1.3 supply module is operated from
the mains supply via auxilary devices.
The auxilary devices are available as either compact mains connection
module NAM 1.3 or in the form of individual components.
All the necessary components like the commutation choke, storage capacitor
and DC bus smoothing choke, are in the mains connection module. This
keeps installation work to a minimum.
