Technical Description
C250 Series Power Calibrators are used to calibrate and test single-phase power measuring devices such as: electric meters, phase meters, frequency meters, intensity meters, voltage meters, and probes for the above parameters.
The C250 Calibrator is a single-phase AC voltage and current source. It is capable of generating a default AC voltage of 240V, a default AC current of 10A and 20A, a default frequency of 50Hz and a phase shift with default values of 0° and 60°.
With the C250M model, current, voltage, power factor and frequency values are displayed simultaneously on the LCD screen thanks to the integrated meter. The output current and phase shift values are selected by pressing the buttons on the device.
In remote control mode, the above values can be adjusted using an additional external keyboard or from a computer via the RS232C/USB port.
The test device can be safely connected to the calibration power supply without adjusting the set value, as the standby function can be simply turned on to isolate the output.
The C250 Series Calibrators are designed and built in a lightweight aluminum housing and compact size.
