1、 Introduction

Ppsd series linear program-controlled signal source is designed by Shaanxi blue sea Electric Co., Ltd. for military enterprises, scientific research institutes, universities, communication, transportation and other units that need high-quality AC and DC signal sources

A high performance AC-DC program-controlled signal source is designed

The DC signal source adopts series voltage stabilizing design; the AC signal source adopts DSP and high-precision Da to generate sine wave, which is amplified by high-voltage operational amplifier and then output, so that the signal source has good output performance and system stability.

The circuit adopts modular structure design, which is easy to maintain; the output over-current protection adopts cut-off protection, which has strong adaptability to the impact of load.
