3 Phase Electric Meter Calibration Equipment , AC Voltage Current
The XL-801R three-phase Electric Meter Calibration Equipment
programmable standard power source is a new generation of
high-precision standard power source based on 1.2 G MAC DSP,
large-scale FPGA, high-speed and high-precision DA and
high-fidelity power amplifier. Applicable to electric power system,
electric power, remote control, dispatching and other power
departments and enterprises that need measurement, inspection and
high-precision standard signal sources. It is also suitable for
other occasions where high-precision standard signal sources are
required for measurement and inspection.
XL-801R can output high-precision voltage and current with
adjustable frequency, phase and amplitude at power frequency
(40Hz~65Hz). It is a highly accurate adjustable voltage and current
standard source. The XL-801R can output very pure sinusoidal
voltage current with a distortion of no more than 0.2%, typically
0.05%. The XL-801R's voltage-to-current output has a very high
output stability, typically 0.01% RD. Therefore, it is very
suitable for work situations requiring high-precision inspection
and calibration, such as the measurement department for the
detection of various voltage, current, power and other electrical
