Product Description

Product Introduction

The DS1000 series DC power supply is a high-frequency switching DC power supply utilizing PWM technology. Featuring a modular design and advanced DSP digital control technology, it ensures high-precision output with low ripple, fast dynamic response to voltage and current changes, and efficiency up to 93%. Compared to traditional thyristor-based power supplies, high-frequency switching DC power supplies offer advantages such as compact size, light weight, low ripple, high power factor, and excellent stability—particularly notable for high-voltage output stability. This product is primarily targeted at applications requiring high-precision DC power in electronic power production, battery manufacturing, PCB board manufacturing, communications, PLC power supply, electromechanical aging testing, research institutions, and laboratories. It serves as a replacement for imported medium-to-high-power DC power supply products.
