New XWave Frequency Converter
Ametek Programmable Power introduced the Elgar XWave high-power AC power source/frequency convertor. The XWave Series delivers high-power density, efficiency and modular flexibility using advanced MOSFET-based, switch-mode power conversion technology for a wide range of common AC power source applications, including:
• Product design and acceptance testing to world-wide AC mains voltage and frequency standards
• Simulation of high-frequency AC bus parameters for aircraft and marine equipment
• High-power AC mains power conditioning for sensitive equipment
• Replacement of noisy and inefficient motor-generator sets
The design of the XWave Series utilizes 10kW power modules to provide incremental output levels from 30kVA to 480kVA. A single cabinet can provide 120kVA with multiple cabinets configured for outputs from 120kVA to 480kVA. Its interchangeable components facilitate on-site repairs and, should future requirements change, permit field upgrades and improvements.
The XWave provides up to 150% of rated output current for up to 7 seconds to handle loads with heavy in-rush currents, and it has a line drip compensation feature to overcome distribution losses.
Standard models are offered with single or three-phase outputs in a variety of single or dual output ranges. Custom voltage outputs are available. All models offer both automated and manual control of voltage and frequency either through the front panel or analog control.
The XWave has a standard frequency operating range of 45 to 1000 Hz. This permits simulation of existing and emerging power bus standards for aircraft and marine applications. A no-cost option also is available that limits the top frequency to 500 Hz. A soft start feature protects input service from disturbances while enhancing reliability. Zig-zag multi-phase input rectification minimizes input line disturbances and provides a typical power factor of 0.8.
