UL safety testing institute is the most authoritative in the United States, is also engaged in safety testing and certification of the larger civil organizations! After nearly 100 years of development, UL has become a world-renowned certification body with a set of rigorous organizational management system, standards development and product certification procedures. Currently, UL has five laboratories in the United States, with headquarters in Northbrook, north of Chicago, as well as facilities in Taiwan and Hong Kong.

In 2017, for the first time, UL headquarters laboratory in the United States for the Zhengyangxing resistive load resistance box technical parameters and the strength of Zhengyangxing company recognized, and determined to produce 2 20A@120Vac / 240VAC double voltage resistive load box for trial!





2020年,经UL纽约实验室推荐,正阳兴再次得到UL另一实验室对于阻性负载电阻箱的洽谈,并取得了8台双电压阻性假负载箱7.4kW@120Vac /240Vac订单的良好合作。同时在产品到达美国使用一个月后,我们收到了UL公司使用部门对于正阳兴负载电阻箱的良好认可!




So far we love these load boxes. All my technicians love to use these load resistor boxes because they are easy to operate and small in size. The only drawback is that the fan is a little noisy, but we know this is a normal phenomenon.
Thanks for the support and recognition from customers all over the world, we will continue to work hard to enhance our technical strength and strive for more and better resistance products and services for customers!
