Product Details

Product IntroductionProduct Introduction

The HT3050 three-phase programmable precision testing power supply produced by Huatian Power is a new generation of high-precision standard power source based on 1.2G MAC DSP, large-scale FPGA, high-speed and high-precision DA, and high fidelity power amplifier. Suitable for power departments and enterprises that require measurement, inspection, and high-precision standard signal sources for electrical measurement, thermal engineering, remote control, dispatch, etc. in the power system, as well as other occasions that require high-precision standard signal sources for measurement and inspection..

HT3050 can output high-precision voltage and current with adjustable frequency, phase, and amplitude of the power frequency (40Hz~65Hz), making it a very high-precision adjustable voltage and current standard source.

HT3050 can output very pure sine voltage and current, with distortion not exceeding 0.1%. The voltage and current output of HT3050 has a very high output stability, with a typical value of 0.03% RD. Therefore, it is very suitable for work situations that require high-precision inspection and calibration, such as the detection of various voltage, current, power and other electrical parameter meters in metrology departments.

Harmonic output	The HT3050 three-phase programmable precision test power supply can accurately output 2-22 harmonics, and each harmonic can be combined and stacked together at any time for output. However, the total harmonic content of the output harmonics should not exceed the limits listed in the table below.
Harmonic output	The load capacity of HT3050 will be reduced by half when outputting harmonics. To ensure reliable and accurate harmonic output, please ensure that the load does not exceed half of the rated value. Especially for voltage output, as it is often used as a power source for the device being tested, the power consumption on it will be relatively high.

Product FeaturesProduct Characteristics

1. This three-phase programmable precision testing power supply can output pure sine power signals with a distortion of 0.1% (typical value).
2. It is possible to superimpose various harmonic outputs on the fundamental wave.
3. The frequency output can be adjusted from 40Hz to 65Hz, with a resolution of 0.005Hz and an accuracy of 0.005Hz.
4. A and B phases are a frequency reference, while C phase is a separate frequency reference, so it can be phase separated and frequency converted.
5. The phase can be adjusted from 0 to 360 degrees, making it easy to simulate various power supply situations, even reverse power transmission situations.
6. Strong carrying capacity, capable of carrying capacitive, inductive, resistive loads or composite loads, with a load adjustment rate better than 0.03% RG.
7. Excellent temperature stability, the core component is a military grade product with a temperature coefficient as small as 1PPM, which can ensure output accuracy in outdoor temperature environments.
8. Adopting a 32-bit MCU+DSP processor, it has powerful and flexible functions.
9. The waveform of up to 50000 points per cycle of the power frequency is pinched, and the internal signal output does not require a filter for smooth filtering, ensuring the accurate output of the waveform, allowing the system to output precise harmonics, and also giving the system excellent harmonic distortion indicators.
10. It can be easily connected to a PC through RS232 to expand other functions.
11. Complete overcurrent, overvoltage, overheating, short circuit, open circuit, and overload protection.
12. Hardware PID, extremely responsive, and changes in load will not cause any fluctuations in output.
13. 320 * 240 LCD display, Chinese interface, easy to operate.
14. Open communication protocol to facilitate secondary development (factory automatic calibration of RTU/FTU/electricity management terminal/public transformer metering terminal).
15. The three-phase programmable precision testing power supply can carry pure capacitive loads.
16. Combined with PC software, the energy meter can be verified.
