Load banks are essential precision devices for simulating actual operating conditions and verifying equipment performance in the R&D testing, factory inspection and daily maintenance of power equipment such as generator sets, UPS and inverters. As a three-phase AC load bank, Ningbo Zhimao ALB-SR Series addresses the key pain points in power testing. Featuring three core strengths of high-precision measurement, wide power adaptability and all-round safety protection, it stands out as a top choice for industrial power testing and is widely applicable to performance inspection of various industrial power equipment.
High precision measurement constitutes the core advantage of the ALB-SR Series. Equipped with high-precision measuring circuits and intelligent sensor modules, it achieves a measurement accuracy of ±0.1% for key parameters including voltage, current and power, far exceeding ordinary industry standards. With a minimum power resolution of 1W, it can accurately capture subtle load variations, fully meeting the demands of sophisticated testing. The device supports real-time data acquisition, recording and storage, and enables data traceability and analysis when connected to a computer. Boasting a 1-millisecond ultra-fast response and cyclic testing functions, it precisely simulates power on/off and load fluctuation conditions, providing authentic and reliable data for product R&D optimization and factory quality inspection.
This series features a wide power range with multiple power grades available, covering all testing scenarios from low-power precision tests to high-power full-load inspections. It is compatible with standard three-phase AC 380V industrial voltage and 50/60Hz power frequency. The power can be adjusted flexibly, and it allows custom setting of 0 to 30 groups of programmable power and current parameters. It works perfectly for aging tests of small power modules, load tests of medium-sized UPS, as well as full-load, overload and sudden load change tests of large generator sets. One unit fulfills diverse testing needs and effectively cuts down equipment procurement costs for enterprises.
Industrial testing imposes strict requirements on equipment safety, and the ALB-SR Series is fitted with a comprehensive multi-protection system to eliminate potential risks. It integrates protection and alarm functions against overvoltage, undervoltage, overcurrent, short circuit, overtemperature and fan failure. It monitors operating status in real time, and will trigger alarms and cut off power automatically once abnormalities occur. Further equipped with a physical emergency stop switch, three-phase phase sequence detection and real-time temperature monitoring, it builds solid safety barriers. Its core power consumption components are made of high-quality shock-resistant aluminum alloy, delivering high heat dissipation efficiency without overheating. The equipment runs stably with low noise, suitable for continuous operation in workshops, and boasts excellent durability and safety.
In summary, with outstanding testing accuracy, versatile adaptability and reliable safety safeguards, Ningbo Zhimao ALB-SR Series Load Bank solves common drawbacks of conventional load banks such as low precision, limited power range and insufficient safety. It is an indispensable professional testing device for the production, R&D and maintenance of power equipment.
