Ametek Tahoe Series - Programmable AC and DC Power Supplies

The California Instruments Tahoe Series combines intelligence and flexibility with high power to create an advanced platform of programmable AC/DC power sources.

Using a state-of-the-art SiC power switching architecture and Digital Signal Processing, the Tahoe Series combines a robust, high-power AC/DC source with an advanced power analyzer in a single-floor standing chassis.

This easy-to-configure high-power source covers a wide spectrum of single and three-phase AC power sources or single-channel and multi-channel DC power supplies at an affordable cost. Tahoe Series can fulfill your power test requirement with add-on test application routines for military and commercial avionics testing.

Features and Capabilities:

• Dual Voltage ranges that support over-voltage testing on 480V-based systems
• Separate terminal blocks for single-phase and three-phase AC power supply outputs
• High Power AC and DC Source
• Auto paralleling for higher power system expansion
• Single and three-phase modes
• Arbitrary & Harmonic Waveform Generation
• Standard LXI LAN, USB, and RS-232, Optional GPIB
• Step, list, and pulse voltage transients with down to 500usec resolution
• Complete avionics power quality test suites
• 15kVA to 1MVA Power Levels
• Intuitive 5” color display for ease of navigation
• Internationally accepted test routines for EMI/EMC, Safety Compliance

Simple Operation

The Tahoe Series can be operated completely from its menu-driven front panel controller. The full-color touch display shows menus, setup data, and read-back measurements. RS-232C, USB, and LAN remote control interfaces and instrument drivers for popular ATE programming environments are available. This allows the Tahoe Series to be easily integrated into an automated test system.

With the programmable arbitrary waveform generator, the user can generate application-specific waveforms, obtain time and frequency domain measurements, and capture actual voltage and current waveforms.

Configurations

The Tahoe Series offers five single chassis configurations: 15kVA, 22.5kVA, 30kVA, 45kVA, and 90kVA. For high programmable AC power requirements, multi-cabinet models are available. These systems offer Reflex capability, allowing flexible user reconfiguration as needed. This ability to reconfigure the system greatly expands your test coverage and is not commonly found in power systems.

Choice of Voltage Ranges

The Tahoe Series offers dual range 0 - 166V & 0 - 333V line to neutral direct coupled output. These models provide a maximum three-phase AC power supply output capability of 287 VAC & 576 VAC line to line respectively. For applications requiring more than 333 V L-N (or 576 V L-L), optional transformer coupled ranges up to 715 V L-N and 1,238 V L-L are available. Or, for custom applications, tell us your requirements and we’ll design the configuration you need.

High Crest Factor

With support for high crest factor loads, the Tahoe can drive difficult nonlinear loads with ease. Since many modern products use switching power supplies, they tend to pull high repetitive peak currents. The TA30 with a crest factor rating of 4.5, for example, can deliver up to 300 Amps of repetitive peak current (166 V AC range) per phase to handle three-phase loads. Refer to the specifications for peak repetitive currents for each model.

Remote Control

Standard RS232C, USB, and LAN, along with optional GPIB remote control interfaces, allow the programming of all instrument functions from an external computer. The popular SCPI command protocol is used for programming.
