The LS3300 AC power calibrator can accurately and stably produce a wide range of AC power outputs for the calibration of power meters and other types of power measuring instruments. Focusing exclusively on power meter calibration, the unit promises to dramatically reduce calibration costs. Features include:
- Reduced cost: The LS3300 can calibrate AC voltage, current, and power as well as test both phase difference and power factor. While costing considerably less than other calibrators due to focusing exclusively on power calibration, the LS3300 delivers a high accuracy of ±0.045% and a superb stability of ±0.01% per hour.
- Ideal for calibration of large-current measuring instruments and current sensors: Unlike many other calibrators on the market, the LS3300 includes as a standard feature, the ability to output currents of up to 62.5 A for extended periods of time. Further, three LS3300s can be synchronized to easily output currents of up to 180 A, thus enabling the calibration of instruments such as smart meters and shunt-resistor current sensors and other devices that require higher currents.
- Ideal for calibration of three-phase AC power: One LS3300 unit can calibrate single-phase power meters. Multiple LS3300s can be used together to calibrate power meters used in single-phase three-wire AC power and three-phase AC power measurement. Using the multiunit control features of the LS3300, it is possibly to automatically set the voltage, current, power factor, phase, and other values on slave devices by updating those settings on the master unit. This significantly reduces the amount of time needed for single-phase three-wire and three-phase AC power calibration.
