China Ht3050 Three Phase Program Control Precision Power Source

Product overview
HT3050 composed by DSP of 1.2G MAC, large FPGA, high precision DA and high fidelity power amplifier. Applies to test the electric test, heat engineering, tele-mechanical, dispatch and others electric department and enterprise which need test and inspect the high-accurate signal source of electric system.
HT3050 is a high-precision adjustable voltage and current standard source which can output power-frequency (40Hz ~ 65Hz), phase and adjustable high-precision voltage and current,. HT3050 can output pure sinusoidal voltage and current, the distortion does not exceed 0.1%. HT3050 with high-stability, the typical value is 0.03% RD.
Products features
1. Can output pure, distortion 0.1% sine wave signal.
