Product Description

1. Overview

The POW-7.5KV-2W features an aluminum alloy power supply housing with excellent electromagnetic shielding performance, compact size, and fully solid-state, spark-free operation. It has low switching interference and is easy to operate. Both current and voltage are displayed digitally, with voltage accuracy of 1V and current accuracy of 0.1µA. The power supply uses a shared display for both current and voltage, minimizing the overall size. The power supply supports dual power modes: it can operate on 220V AC input or 12V DC input, making it suitable for both indoor and field use. Additionally, it offers a voltage setting display function, which ensures that high voltage is not output when the voltage is being set, and only activates after the output switch is pressed. The system also supports customizable RS232 CAN bus intelligent control interfaces. The high voltage output uses a multi-turn potentiometer for precise control.
