The LSX Series AC Power Source is designed for low power, ranging from 1.5kVA/kW up to 6kVA/kW in single and three phase. This AC power source has an advanced PWM programmable controller and is a cost-effective option for frequency conversion, advanced power line disturbance tests, aerospace compliance, ATE, appliances, and UPS applications. Units are conservatively designed and output power ratings are based on the worst case combination of input line, output voltage, power factor, and temperature.
For applications not requiring advanced features, a basic function set M version of the LSX is available. Applications range from simple, manually controlled frequency conversion (LSXM versions) to harmonic testing and sophisticated bus programmable transient simulation (LSX versions).
For requirements higher than 6kVA, see ADF Series and AFX Series.
Programmable Output Impedance provides the operator with the ability to dynamically control the output impedance of the AC Power Source. Using the output current term as conditioned feedback signal to the output voltage circuits, positive or negative impedance may be programmed. This control simulates the effects of, or compensates for high peak current, distribution, or transformer losses of up to ±10% of the output voltage. This feature creates positive, negative, or zero output impedance (Zo).
All LSX Series models support direct coupled output voltages up to 135VLN or 270VLL on single phase models or 135VLN/234VLL on three phase models. For higher voltage output applications on three phase models, the transformer option (T-Option) offers three transformer coupled output ranges at ratios of 1.5:1, 2.0:1 or 2.5:1 for a maximum output voltage of 600VLL in split phase or or 585VLL in three phase mode.
Voltage, Waveform and Frequency output transients are easily created from the front panel using an intuitive spreadsheet style data entry method. Data may be entered for a specific phase or for all three phases at the same time. The LSX Series supports LIST, PULSE and STEP Mode Transient Types. In addition to sine wave, the LSX Series offers multiple selectable AC waveforms such as clipped sine wave at various distortion levels, square, triangle and stepped squares.
