SAN DIEGO, CA (December 6, 2022) – AMETEK Programmable Power is pleased to unveil the new California Instruments Sequoia and Tahoe Series of precision programmable AC and DC sources. The Sequoia Series is a full four-quadrant regenerative grid simulator with an optional regenerative electronic load mode, and the Tahoe Series is a two-quadrant AC and DC source. Both Series are named after beautiful natural wonders in the state of California, honoring the great California Instruments brand and paying homage to the state where these products are proudly manufactured.

The Sequoia and Tahoe Series combine intelligence and flexibility with high power to create an advanced platform of AC solutions. Using a state-of-the-art SiC power switching architecture, they incorporate compactness, robustness, and functionality in a floor-standing chassis. The Sequoia Series is designed to refresh the MX and RS Series, while the Tahoe Series will refresh the BPS Series. Their launch provides an opportunity for both new and existing customers to upgrade from the MX, RS, and BPS Series.

The Sequoia and Tahoe Series are easy-to-configure power sources which cover a wide spectrum of single and multi-phase AC or single channel and multi-channel DC power applications at an affordable cost. Such applications include power conditioning equipment testing, grid interactive green energy and distributed power generation, avionics and shipboard electronics testing, regulatory compliance testing, electric vehicle testing, manufacturing line testing, and more. With the add-on electronic load option, the Sequoia Series can support additional advanced renewable energy simulation and test requirements.

Sequoia Series Highlights:

  • Dual Voltage ranges that support over voltage testing on 480V based systems
  • Instrument Setups for quickly re-establishing the known instrument state
  • 500uS time resolution for Transients
  • Non-Linear current waveform programming during Load mode
  • Phase coordination among multiple units (LKM/LKS)
  • Powerful set of analog controls for PHIL and Modulation tests
  • Trigger In & Out to permit extensive coordination with external systems
  • Extensive Onboard diagnostics
  • Digital I/O, including RS232, USB, Ethernet (GPIB optional)
  • Auto-paralleling for maximum flexibility with multi-chassis configurations

Tahoe Series Highlights: 

  • High Power AC and DC Power Source 
  • Auto paralleling for higher power system expansion 
  • Arbitrary & Harmonic Waveform Generation 
  • Standard LXI LAN, USB, and RS-232, Optional GPIB 
  • 500uS time resolution for Transients 
  • Internationally accepted test routines for EMI/EMC, Safety compliance
