ELGAR SW5250A-1-3-2 AC Power source Factory calibration

This Ametek Elgar SW5250A-3-3-2 has just been factory calibrated. It is in very good condition. One of the advantages of this configuration is the first -3 in the option chain represents PFC input. This takes the unit from about 70% efficiency to about 92% efficiency, thus saving the user a lot of electricity usage and thus “money”.

  • Description

This Ametek Elgar SW5250A-1-3-2 has just been factory calibrated. It is in very good condition.

The Elgar SmartWave™ (SW) Series of AC power sources offers powerful waveform creation for ATE and power line disturbance simulation testing. Three separate arbitrary waveform generators enable the SmartWave to create independent, complex waveforms on all three phases simultaneously. The SmartWave is designed to meet waveform requirements including DC content (up to 312V), low distortion (THD 0.25% to 100 Hz), low noise and ripple, plus full compliance testing to many EMC and avionics standards. At only 8-3/4 inches high for the SW 5250A, the SmartWave delivers the most power in the smallest package. The SW Series is expandable from 1.75 kVA to 22.2 kVA. Unlike other AC power sources, the SmartWave delivers full rated power to 45ºC.. Features and Benefits Powerful Waveshape and Waveform Creation The SmartWave can easily create fractional or multicycle dropouts, spikes, surges, sags and distorted waveforms from the front panel. To simulate these complex real-world power occurrences, the SmartWave comes with a library of 50 built-in waveshapes (see examples on page 74). Users can create and store an additional 50 waveshapes of their own design. Output voltages are created by adding amplitude, frequency and other parameters to the waveshapes. The user can also create over 50 custom front panel setups with all parameters included and store them for quick recall, making the SmartWave ideal for manual testing. Sequence Programming Complex sequence or event programming is easy with time or cycle based transient segments. The sequence library is made up of a total of 1000 segments. A sequence of up to 100 segments using up to 32 different waveshapes, arranged in any combination, can be run at any one time. The 32 waveshapes can be selected from the 50 factory supplied and 50 user created waveshapes. By setting the time or number of cycles for each segment, the user can create waveform sequences that allow automatic testing for most any standard. Elgar SmartWave Series 1750–22200 VA •
