 Introduction

  Dc voltage transformer stabilized power by filtering and rectifying power supply circuit, benchmark voltage circuit, voltage, current, adjusting circuit is amplifying circuit and stabilized sampling circuit, etc. When the output voltage power supply voltage or current due to changes in load changes, the change of signal sampling circuit voltage stabilizing compared with benchmark, the income error signal amplifier amplification, by comparison of linear adjustment for fine adjustment, make the components of the high-precision dc voltage source output.
Summarize
  Dc voltage is stabilized power supply a new precision line DC voltage adjustable stabilized power products, the power supply voltage source adopts the high performance benchmarks components and the most advanced technology and application of circuit control before stabilizing accurate way to work after work, making it has stable performance, DC output ripple voltage, low noise, small voltage characteristic of high precision, good, fast response time, protect circuit is perfect, work safety and reliability. Can be widely used in industrial aluminum erosion, fu can (into), battery manufacture high quality, electroplating, tantalum capacitor can assign electrolytic capacitors, tactful, lead into and resistors, relays, motor, power of semiconductor devices, college laboratory aging production, research institute, telecommunications and automation equipment use.
