Elgar SW5250A SmartWave AC Power Source 5.25kVA

The Elgar SW5250A is a 5250VA AC power source designed for simulating and testing various AC power conditions. It is engineered for applications such as product testing, avionics testing, and power supply testing, offering precise and reliable AC power output. The unit is capable of simulating complex real-world power occurrences, including voltage dropouts, spikes, surges, sags, and distorted waveforms, utilizing an internal library of built-in and user-creatable waveforms. Its design allows for three-phase or single-phase operation and can be expanded through a master/slave configuration for higher power requirements.
