In the R&D, mass production quality inspection and aging testing of new energy power equipment, testing the load stability, power output accuracy and operating condition adaptability of EV chargers and grid-tied inverters is the core link to guarantee product quality. Conventional testing equipment suffers from low precision, limited operating condition simulation and inadequate safety protection, which often leads to test data deviation and equipment damage. Tailored for new energy testing scenarios, the Ningbo Zhimao ALB-DR AC single-phase simulated load features high testing accuracy, flexible operating condition simulation and comprehensive multi-protection functions, making it an indispensable professional testing device for the EV charger and inverter industry.
Equipped with a high-precision detection system, this simulated load achieves a core testing accuracy of 0.5%. It delivers precise and controllable voltage and current resolution, with a minimum load resolution of 1W and supports wide-range power adjustment from 0.1kW to 30kW, accurately capturing the operating status of devices under slight load changes. Adopting high-quality stainless steel alloy resistors and a reliable electrical structure, the device features low resistance error and uniform heat generation, maintaining stable load performance for long-term operation. It effectively avoids resistance drift and distorted test data of traditional load equipment, and is perfectly applicable to full-load, light-load and intermittent load tests for EV chargers, as well as performance verification of inverters under grid-tied and off-grid operating conditions.
Flexible operating condition simulation stands as a core advantage of the ALB-DR series. The device supports dual control modes: manual switch operation and program control. Users can freely combine power gears and set discharge power precisely. It also simulates extreme working conditions such as sudden power increase and decrease, reproducing complex load environments in actual operation. Whether for performance commissioning in new product development, full-item inspection before factory delivery or long-term aging reliability testing, it can accurately verify the load capacity, operating efficiency and response speed of EV chargers and inverters. It helps enterprises detect potential faults and improve product reliability.
The fully upgraded safety protection design builds a solid barrier for testing. The device is embedded with multiple intelligent protection functions including over-temperature, over-current, overload and short-circuit protection. Equipped with real-time temperature monitoring, it precisely tracks temperature within 0-100℃ and automatically cuts off power and shuts down under abnormal conditions, preventing equipment burnout and circuit faults. Meanwhile, the optimized heat dissipation structure ensures efficient heat dissipation under high-power operation. The device can operate continuously and stably for a long time, well suited for assembly line batch testing in factories and greatly boosting testing efficiency.
Overall, the Ningbo Zhimao ALB-DR AC single-phase simulated load integrates high precision, excellent stability and superior safety, compatible with various testing scenarios for single-phase new energy power equipment. With reliable hardware quality and a complete protection system, it provides solid support for quality inspection of EV chargers and inverters, and serves as the preferred equipment for quality control, R&D and aging testing in new energy electrical enterprises.
