In general, the larger the analytical instrument, the higher the power requirements, and the optical emission spectrometer is no exception. A stable power supply is extremely important for the reproducibility and reproducibility of the measured data of the optical emission spectrometer.
Due to the large fluctuation of the voltage in front of the furnace, the voltage of the power supply is difficult to stabilize and cannot provide a stable voltage for the optical emission spectrometer. In order to ensure the normal operation of the optical emission spectrometer and the accuracy of the measurement data, a suitable regulated power supply is required to ensure that the instrument is relatively stable. The voltage. The instrument requires its power supply voltage to be controlled within ± 5%, which will not affect data measurement and instrument life.
The optical emission spectrometer power line connection is prohibited from sharing a power supply line with large electrical equipment such as electric motors, ventilators, air conditioners, muffle furnaces, etc., and it cannot share power with production equipment such as intermediate frequency furnaces. The large fluctuation of the voltage of the power supply line will also cause the power supply voltage to be unstable. In general, the 1KVA magnetic saturation stabilized power supply can meet the requirements of the optical emission spectrometer. In order to stabilize the power supply, an AC contactor (manual control (start, stop)) should be installed before the stabilized power supply 220V / 45A), the AC contactor is installed in the wall distribution box about 1.5m above the ground.
During the operation of the optical emission spectrometer, you should also observe the change of the stabilized power supply device to see whether the indicator light shows whether it is over-voltage or under-voltage. If this happens, the optical emission spectrometer should not stimulate the work because the voltage of the optical emission spectrometer is running Exceeding ± 5% will cause the output power of the high-frequency generator to be unstable, which will greatly affect the reproducibility and reproducibility of the measurement data, and will also affect the life of the high-frequency generator.
