Overview
Hospitality Enviro Tech portable DC voltage tester adopts PWM high frequency pulse width modulation technology for closed-loop adjustment, with high voltage stability, small pulsation factor and fast and reliable protection circuit. The display adopts green backlight and wide temperature liquid crystal display, which can clearly display data in strong light and dark. DuPont new filling material is used for high pressure parts, which makes the product performance more stable and reliable. The products are widely used in preventive experiments and scientific research institutes of power generation and power supply departments, power transmission and transformation engineering companies and large-scale factories and mining enterprises as DC high voltage regulated power supply.
