Power standard source is a kind of voltage and current signal generator. The device can independently adjust the magnitude of voltage and current and the phase difference between the two. The device also includes a can be standard tables for accurate measurement of voltage, current, frequency and voltage and current synthesis of virtual power, showing the standard table of values as compared with the reference standard, with variable frequency power as the main object of measurement of various measurement device / system calibration and verification. As a measuring standard instrument, its metrological characteristics must meet the requirements of relevant regulations. Characteristics of output capability and quality standard of good power source used on digital electronic technology as the leading factor, capable of providing up to 1000A and 10KV voltage and current output, the basic accuracy of 0.05% and phase angle between the voltage and current amplitude, frequency and both are independent and adjustable. Besides the sine wave voltage and the current, the voltage output and the current output can also be provided with accurate and harmonic distortion. All of the first 100 harmonics can be set by the user, the amplitude and phase of each harmonic can be controlled by the user. The addition of harmonics does not significantly weaken the accuracy or traceability of measurement. Protective measures of high \ \ products run in the high voltage output state exists high risk, you can ensure your safety operation: \ \ shell are printed on the conspicuous warning signs; \ \ separation machine structure design, the operator with a standard source high voltage output terminals can be set aside enough safe distance; \ \ operation terminal and the signal generating device to optical fiber communication, physical separation blocking high voltage electrical hazards; load ability of excellent power standard source to guarantee under the heavy load still give you need the output voltage and current. Voltage channel in the 10kV output can provide 50mA drive current, the current channel output in the 1000A can provide the output voltage of 3V. This is especially important when you test multiple devices in order to improve the efficiency of your work. Moreover, it is particularly important that the source and test stations, which are far apart from you, can not be given the required voltage and current due to the influence of the cable. Support multi phase system AT series instrument for single phase system, when you need to change the calibration channel, you can increase the number of output by parallel mode, up to six phase. The basic technical indicators will not change because of the increase in the number of output phase. Graphical interface friendly power standard source system control program based on Windows graphical user interface. This convenient and intuitive program controls all the functions of the standard source. You can use the button on the instrument to operate, you can also use the keyboard and mouse operation. Electromagnetic compatibility performance excellent power standard source always implement the electromagnetic compatible concept, with excellent shield is connected to process, reasonable filtering measures, based on optical fiber transmission of digital closed-loop control eliminate the influence of external disturbances, as the standard source output stability and EMC of can provide a reliable guarantee.
