Product Description
GF301 AC Sample Calibration Device (Accuracy class 0.02/0.05) Application It is suitable for all power dispatch center automation departments, power supply company and power plants far move class, also suitable for oil, railway and steel industry etc power automation departments use. Main function and features: 1, output fastest (10 ms) : by high performance 32 bit MPU + DSP + FPGA, the frequency of 1.2 G; 2, stable fastest (1 s) : hardware PID, the output of the standard resource without delay, fast response; 3, with the strongest load, load regulation rate fast, single phase with resistance sex load 30 VA; With pure capacitive load (0.33 uf); 4, harmonic supreme: standard resource can output 2-128 times higher harmonic; 5, the smallest light: the integrated module, volume domestic the minimum; And the lightest weight (11 kg); 6, stability, and the best, stability for 0.005% / min; 6, output two kinds of frequency: but at the same time points, two kind of frequency phase output voltage; And amplitude can adjust arbitrarily output; 7, software powerful, the operation is simple, convenient, quick, three steps can complete verification; 8, debugging far move communication protocols of the most, as many as 20 kinds, covering domestic all factories statute; 9, verification fastest: national rules for verification of 84 points, three minutes after inspection; 10, at first only to produce a magnitude 0.02 ac sample verification equipment manufacturers, represents the domestic leading level; 11, and the use of virtual load calibration ac sample error, can fully automatic, semi-automatic and manually check; 12, to calibrate the same period device 13, with the flow, over-voltage, heat, a shorts-and-opens, overload protection, automatic failure detection. Technical Data Three-phase AC voltage output Range: 57.7 V / 110 V / 220 V / 380 V; Accuracy: 0.02% / 0.05% RG; Adjusting range: (0-120) % RG; Adjust fineness: 0.01% RG; Stability: 0.005% / 1 min; Distortion degree: ＜ 0.1%; Output load: each phase 30 VA; Load regulation rate:
