California Instruments 4500Ls Programmable AC Power Source 4.5kVA

Description

The Ls/Lx Series is a completely improved new product based on the popular California Instruments L Series. Both the Ls and Lx feature many basic AC Source capabilities at a very reasonable price. For more information on either product, please click on the product tab on the right.

The Ls Series is an improved version of the classic California Instruments L Series AC power sources. It provides many basic AC source capabilities at an economical cost. Additional capabilities such as arbitrary waveform generation and harmonic measurements can be added as options. The Ls Series can be ordered in either single phase (-1) or three phase (-3) configurations. Power levels range from 3 kVA to 6 kVA in a single chassis. Multiple chassis can be combined for power levels up to 18 kVA. The Ls Series is completely microprocessor controlled and can be operated from a simple front panel keypad. A pair of analog controls located next to the backlit alphanumeric LCD display allows output voltage and frequency to be slewed up or down dynamically. For more advanced operations, a series of menus is provided using a dual line high contrast LCD display. The Lx Series represents a modern AC power source that addresses increasing demands on test equipment to perform more functions at a lower cost. By combining a flexible AC power source with a high-end harmonic power analyzer, the Lx Series systems are capable of handling applications that would traditionally have required multiple instruments.

 

Features

  • Backward Compatible with L Series – Function and bus compatible with the California Instruments L Series
  • Three phase and Single phase modes – Ideally suited for avionics and defense applications
  • 3 KVA to 18 KVA Power Levels – Match power source and cost to application requirements
  • Transient Programming – Test products for susceptibility to AC line disturbances
  • Built-in Measurements – Performs voltage, current, and power measurements
  • Advanced Features – Arbitrary waveform generation, harmonic analysis, GPIB interface are some of the available options
  • Interface – Standard USB & RS232C interface. (Optional GPIB & LAN available)
  • CE Marked (400V input model ONLY) – Safe, reliable, and consistent operation
