We offer our most popular configurations; however, if you need a different configuration, please complete the following questionnaire, click on submit and we will call you within the next business day with a quote for an M-3425A including your specific options. Domestic shipments are F.O.B. factory. International shipments are FCA factory. Prices subject to change without notice. Prices listed are in USA dollars. All orders are subject to Beckwith Electric Co., Inc. standard terms of agreement.

DESCRIPTION: The Integrated Protection System ® M-3425A provides protection, control, monitoring and user interface functions for generator protection. Stored targets and oscillography can be IRIG-B synchronized. Dual RS-232 ports and an RS-485 port provide user-interface communication access. The M-3820D IPScom ® Communications Software is included for direct serial or remote communication access. Waveform data can be downloaded using the M-3801D IPSplot ® PLUS Oscillographic Analysis Software which allows for plotting and printing of the downloaded oscillographic data. Optional modules include the HMI Module for front-panel operation, the Target Module to indicate trip target status and redundant power supply.
 

Select either the M-3425A Comprehensive or the M-3425 Base protection system, then select optional features.
