Product Name: LPB AC / DC linear combination power supply
1、 Introduction
Lbp-a10026 / d2812c linear combination program-controlled power supply is specially designed for military enterprises, scientific research institutes, universities, communications, transportation and other needs of high quality
AC and DC power supply unit and the design and manufacture of High-Performance AC and DC program-controlled power supply.

The DC power supply adopts series voltage stabilizing design, the AC power supply 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

Qualitative. The output over-current protection adopts cut-off protection, which has strong adaptability to the impact of load.
