CRITEC TDS-MPM

The CRITEC TDS MPM MOVTEC Protection Module offers a most reliable protection from power transients in even the most strenuous of applications. It is widely specified within the telecommunications industry as the main defence against transient damage in what are typically considered high risk applications. The introduction of Transient Discriminating (TD) technology introduces a great leap in transient suppression technology, providing a new level of safety and reliability while retaining optimum protection, critical for sensitive electronic equipment. TD technology is essential for any site where abnormal over-voltages can occur, or where there is possible catastrophic failure of traditional surge technologies. A patented electronic circuit continuously monitors the health of the internal MOV’s and displays this status on a 5-segment LED bar graph. Alarm contacts are provided which may be used to shut down the system, or activate an external warning if the internal surge material is below optimum condition. Features: • TD technology for superior life • Robust against abnormal over-voltage events • Primary protection for extremely high exposure sites and point-of-entry protection applications • Single mode units provide up to 100kA 8/20µs protection • Three mode unit available provides L-N, L-G and N-G protection in the one unit • Small foot print for more effective use of real-estate • Fail safe voltage free alarm contacts • 5 segment electronic status indication ideal for poorly illuminated locations • Long service life • Lug terminals for connection of large cables • UL Recognized Components, AS3260, IEC 950, C-Tick and NOM approved Applications: • High risk telecommunications facilities, • Defense communications and infrastructure • Large scale Industry and Mining • Vital Public Service infrastructure and IT. • Component for OEMs and panel board builders to integrate into equipment and panel boards • Excellent primary service entrance protection module Models Ordering information   Part No. Description TDS MPM 277 3 Phase MOVTEC Protection Module, 220-277V, 100kA, 5 LED Status Technical Notes TNCR005 Technical explanation on ERICO’s Transient Discriminating Technology Installation Installation notes
