Introduction to the three-phase programmable precision test power supply:

The three-phase programmable precision test power supply is a new generation of high-precision standard power source composed of MAC-based DSP, large-scale FPGA, high-speed and high-precision DA and high-fidelity power amplifier. It is suitable for power departments and enterprises that need measurement, inspection and high-precision standard signal sources such as electrical measurement, thermal engineering, telecontrol, and dispatching of power systems, and is also suitable for other occasions that require high-precision standard signal sources for measurement and inspection.

It can output high-precision voltage and current with adjustable frequency, phase and amplitude of power frequency (40Hz 65Hz), and is a very high-precision adjustable voltage and current standard source. It can output a very pure sinusoidal voltage current with no more distortion than that. The voltage and current output has a very high output stability, and the typical value is .

Therefore, it is very suitable for work occasions that require high-precision verification and calibration, such as the measurement department for the detection of various voltage, current, power and other electrical parameter meters.

The three-phase program-controlled precision test power supply is provided by "Huatian Power" company!

Program-controlled power supply in the sense of patency refers to the power supply that can accept command control. It includes the ability to control the parameters of the power supply with commands, and also includes the ability to read back the parameters of the power supply with commands.

What is a programmable power supply? Programmable power supply.

It is the process of programming instructions and entering them into the machine according to the sequence of operation, so that the machine can operate automatically according to the instructions. What is the use of a programmable power supply? First of all, the programmable power supply is still a power supply. As for program control, it means that the output of this power supply can be controlled by programming.

The standard programmable power supply can generate stable high-power power frequency voltage and current signals with adjustable amplitude, frequency and phase angle. It is mainly used for the test and verification of current, voltage, phase, frequency and power meters; It can also be used with the standard power watt-hour meter to verify and verify the basic error, latent motion and sensitivity of the watt-hour meter (watt-hour meter). What are the brands of program-controlled power supply?

American AMETEK, South Korean ODA, Ajren MEAN WELL.

Zhimao TDK and so on, but I personally think it is the best to use AMETEK, with high precision, good stability, short delivery time and long warranty period.

Jiece, MEAN WELL, Agilent, etc.

Programmable power supply refers to a power supply that sets the output voltage and output current through external control, and the current is stabilized or stabilized. There are generally two programming methods for programmable power supplies: passive and active. The program-controlled test power supply adopts microcomputer control, advanced technology, full control, full button operation, small size, light weight, easy to carry, and can be used in the laboratory and in the field.

The role of programmable power supply:

In some enterprises or power units that need high-precision standard signal sources, the requirements for power supply are extremely high, and program-controlled power supply will be used, so that when the power supply is used, it is more accurate for some measurement and inspection.

Programmable power supply brands: American AMETEK, South Korea ODA, Ajlen MEAN WELL, Zhimao TDK and so on

The control coefficient n is one of the main technical indicators of program-controlled power supply. For the RF system, the coefficient n is the change in resistance required to produce a unit voltage change, and the unit is V. Therefore, the output voltage of the power supply is.

<> RF programming resistor in the formula.

The program-controlled test power supply adopts microcomputer control, advanced technology, full control, full button operation, small size, light weight, carrying party or sleepy, both Huituan Li can be used in the laboratory, but also can be used in the field.
