Read MoreThe Delta Elektronika ES300 Series is a high-precision power supply engineered to meet the demands of laboratory and industrial applications requiring stable and reliable DC power. Delivering up to 300W of output, with a voltage range of 0–30V and a current range of 0–10A, the ES300 ensures accurate performance for sensitive tasks. Its compact and lightweight design makes it suitable for 19” rack mounting or standalone use, even in limited spaces.
Key features include ultra-low ripple and noise for interference-free operation, rapid programming speeds with rise times as fast as 1 ms, and comprehensive overload and short circuit protection. The ES300 Series supports flexible configurations, including Master/Slave parallel and series operations with voltage and current sharing, as well as optional remote sensing for added precision. Designed with convection cooling, it operates silently and efficiently over a temperature range of -20°C to +50°C.
Ideal for applications such as test and measurement, automated test equipment (ATE), controlled battery charging, and medical research, the ES300 Series excels in critical scenarios where precision and reliability are essential. Fully compliant with EMC and safety standards (EN60950, EN61010), it provides robust performance in both industrial and domestic environments.
Choose the Delta Elektronika ES300 Series Laboratory Power Supply for a reliable, versatile, and precision-engineered solution to power your sensitive electronic applications with confidence.
