Main features of Programmable power supply

The standard programmable power supply can generate stable high-power industrial 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 standard power meters to verify and verify the basic error, creep, and sensitivity of the power meters (watt-hour meters).

Program-controlled test power supply adopts microcomputer control, advanced technology, full program control, full key operation, small size, light weight, and convenient to carry. It can be used in the laboratory or on-site. It is a high-precision standard power source, which is composed of a 1.2GMAC-based DSP, a large-scale FPGA, a high-speed and high-precision DA, and a high-fidelity power amplifier.

They are mainly used in some enterprises or electric power units that require high-precision standard signal sources. They have extremely high requirements for power sources. Program-controlled power supplies will be used. This kind of power supplies will be more accurate in measurement and inspection.

The main features are:

1. Provide voltage-stabilized, constant current, phase-shiftable, variable-frequency high-power industrial frequency sinusoidal signals;

2. Test and verification of voltage, current, phase, frequency and power meter can be carried out;

3. It can be used with standard watt-hour meters to verify and verify the basic error, creeping and starting of the watt-hour meter (watt-hour meter);

4. Microcomputer control and program control realize soft start and soft stop, thus avoiding the impact and damage to the instrument;

5. When operating errors, such as voltage short circuit, current open circuit or wiring error, the output can be automatically stopped and an alarm will prompt you to correct;

6. The instrument is operated by key, all key settings are programmed, and the software is interlocked, so random operation will not be damaged;

7. Pure digital waveform synthesis, pure digital amplitude modulation, phase shift, and frequency modulation. Accurate, stable and reliable;

8. The power amplifier adopts imported high-power VMOS devices with high working reliability;

9. Adopt single-chip microcomputer control, super large-scale integrated circuit and other technologies, small size, light weight, and high technical content.
