TK3030 TK3030 three-phase three-phase precision programmable precision test power supply is based on a new generation of high-precision test standard power source 1.2GMAC of DSP, large-scale FPGA, high speed and high precision HiFi amplifier DA constituted. Suitable for electrical power system testing, thermal, remote scheduling and other needs of measuring, testing and high-precision standard signal source and power sector companies, but also for high-precision measurements of the other criteria required signal source, testing occasions. TK3030 three-phase power supply can output programmable precision test Frequency (40Hz ~ 65Hz) frequency, phase and amplitude adjustable precision voltage and current, is very high precision adjustable voltage and current standard source. TK3030 can very pure sinusoidal output voltage and current, the distortion does not exceed 0.1%. HT3050 three-phase test power programmable precision output voltage and current output has a very high degree of stability, a typical value of 0.03% RD. So it is very suitable for applications that require high-precision calibration test workplace, such as metrology meter testing for a variety of voltage, current, power and other electrical parameters table. Products nickname programmable test power, programmable power supply, precision programmable power supply, standard http://www.whgdmk.com/aspcms/product/2014-4-30/131.html product features a programmable power supply, the three-phase programmable precision test power You can output pure, distortion in 0.1% (typ) 2 sinusoidal power signal can be superimposed on the harmonics of the fundamental output 3, the output frequency is adjustable from 40Hz ~ 65Hz resolution 0.005Hz, accuracy 0.005Hz 4, A, B phase as a frequency reference, C phase is a single frequency reference, so the inverter can be divided into five phases, phase adjustable from 0 to 360 degrees, you can easily simulate a variety of power supply situation, even anti-power transmission case 6, strong load capacity, can bring capacitive, inductive, resistive load or complex type load and load regulation better than 0.03% RG 7, excellent temperature stability, temperature coefficient of the core device for small to 1PPM military grade product that can guarantee the accuracy of the output of 8 at the outdoor temperature environment, the use of 32-bit MCU + DSP processor, powerful and flexible 9, the frequency up to 50,000 points per cycle waveform kneading, internal signal output without filter smoothing filter, ensuring accurate output waveform, so that the system can accurately harmonic output, but also the system has excellent harmonic distortion index 10, via a PC connected to the RS232 convenient and expand other features 11 well overcurrent, overvoltage, overheating, short circuit, open circuit, overload 12 hardware PID, fast response, load change did not cause fluctuations in the output of 13,320 * 240 LCD, Chinese interface, easy operation 14, open communication agreement to facilitate secondary development (RTU / FTU / power management Terminal / public variable metering terminal factory automatic verification) 15, three-phase programmable precision test power can bring pure capacitive load 16, combined with PC software can test meter http: //www.whgdmk.com
