The CRITEC® TDS-MOVTEC family of surge diverters offers economical
and reliable protection from voltage transients in even the most strenuous
applications.
The small foot print provides integrators and OEMs with an effective use
of real estate when installing within panels and equipment.
Transient Discriminating (TD) Technology, which meets the safety standards
of UL®1449 Edition 3, provides a superior life by eliminating the common
temporary over-voltage failure mode of most SPDs. TD Technology is essential
for any site where abnormal over-voltages can occur or where the possible
catastrophic failure of traditional technologies can not be tolerated.
Alarm contacts are provided which may be used to shut down the system
or to activate an external warning if the internal surge material is below
optimum condition.
