This is an 18 kW 3 phase 45-512 Hz ac power source.
The full model number is FCS18-3PT-HV3-MODE-OR-PRC-704
Unit said to be working except for some wonkiness on one of the output phases.
California Instruments was bought by another company and they have not responded to any inquiries (email, web form, or returned calls).
Any help finding a manual for this 1200 pound item sitting in my garage would be much appreciated!
