The load box (resistance cabinet) is small in size, occupies a small area and is easy to transport; the load box adopts a wheel type, which is convenient to move.
High accuracy of test data: The intelligent AC load box (resistance cabinet) is an integration of load and instrument, completely separated from external instruments such as voltmeter, ammeter, power meter, frequency meter, etc. The data is collected in real time, and the computer automatically generates the data, and the data accuracy can be adjusted. reached 99.99%.
Constant load power: The intelligent AC load box (resistance cabinet) uses solid-state relays to control the power consumption components of the load, and the high-speed power sampling adjustment module collects and compares data. According to the load power set by the system, using real-time sampling, the feedback power is compared with the set power to realize closed-loop control and power correction.
Safety: Intelligent AC load box (resistance cabinet) is controlled by solid state relay, on/off non-contact switch, the load power is stepless, and no arc will be generated, the operator inputs through the keyboard, the microcomputer issues instructions, solid state The relay is non-contact control, the tester does not need to touch any switch, and the safety is very high.
