Portable resistive load equipment: the preferred choice for power supply testing in South-East Asia

    With the rapid development of the energy storage, domestic power supply, AC charging point and UPS backup power sectors in South-East Asia, there is a need for load simulation equipment that is stable, accurate and convenient for on-site testing,It has become an essential requirement for factory quality control, project acceptance and product ageing tests. The Jianhong JH-RYF-22KWA220-A8A single-phase 22 kW adjustable load cabinet is specifically designed for AC 220 V, 50 Hz mains power supply conditions and is suitable for indoor electrical testing applications in Southeast Asian markets such as Malaysia, Thailand, Indonesia and Singapore.

  This load cabinet utilises chip resistors, has a power factor of 1, a resistance accuracy of ±3 per cent, and offers a wide range of current settings:1A,2A,5A,10A,20A,50A,Gears can be used in combination, stepping accuracy 1A, It flexibly simulates various load conditions, meeting the requirements for stepwise testing ranging from low power to full power (22 kW). The unit is equipped with two digital displays that show power, current, voltage and apparent power in real time; the test data is presented in an intuitive and easy-to-read format, enabling engineers to carry out on-site commissioning and record data more efficiently.

   The cooling system utilises a forced air-cooling design, with a 15050 fan operating in a right-to-left airflow configuration, ensuring stable cooling. It supports continuous 24/7 operation and is unlikely to overheat and shut down even during prolonged ageing tests or batch durability testing. The unit is equipped with multiple safety protections: overheating alarm, overvoltage protection (maximum withstand voltage of 1.1 times the rated voltage) and an emergency stop button. With an IP20 indoor protection rating, it is suitable for dry, well-ventilated environments such as laboratories, factory premises and project server rooms. The operating temperature range is -10°C to 50°C, making it suitable for indoor temperature conditions in most parts of South-East Asia.

  The unit measures ≤400 × 550 × 770 mm and weighs ≤50 kg. It features a combination of a carrying handle and castors, eliminating the need for fixed installation and facilitating easy transport between production lines, client sites and after-sales service locations. The output configuration comprises a set of threaded terminal blocks for resistance leads and a standard socket for auxiliary power. Wiring is straightforward and the learning curve is low. Button-based controls ensure simple operation without the need for complex programming, allowing on-site personnel to get to grips with the equipment quickly.
