JH50KW-AC380V AC Load Tester
In response to the customer’s load requirements, we have developed a set of outdoor‑rated AC 220 V dry‑type load units. This system includes a 10 kW purely resistive load and complies with the technical standards governing the functionality, performance, operating procedures, structure, installation, and testing of dry‑type load test systems and their associated components. It provides users with an efficient and reliable solution for conducting load tests on generator sets and other load‑bearing equipment. Our products have been in operation for many years, undergoing continuous improvement and refinement, making them mature, dependable, and safe. The load test system consists of two main components: the control system and the load bank, which comprise alloy resistors, tap‑change contactors, an electrical parameter data acquisition system, protective devices, cooling systems, auxiliary controls, and more. The load bank is housed in a weather‑proof enclosure, designed for outdoor use.

I. Overview
In response to the customer’s load requirements, we have developed a set of outdoor‑type AC 220 V dry‑type load units. This system includes a 10 kW purely resistive load. The load unit complies with the technical standards governing the functionality, performance, operating procedures, structure, installation, and testing of dry‑type load test systems and their associated accessories, providing users with an efficient and reliable solution for conducting load tests on generator sets and other load‑bearing equipment. Our products have been in operation for many years, with continuous improvements and refinements, making them mature, dependable, and safe.
The load testing system consists of two main components: the control system and the load bank. It primarily comprises alloy resistors, gear‑selection contactors, an electrical parameter data acquisition system, a protection system, a cooling system, and auxiliary controls. The load bank is housed in an enclosure and is designed for outdoor use.
