AC load box to Mao AC relay test load switch power inverter load box load box dummy load current market variety, load box manufacturers Products do hype, then how to find one of these numerous information suitable load box it? We generally consider the following factors: 1) much needed power, that is, to measure power generators or UPS much; 2) is still required to be fixed using movable type; 3) what functions you want to load have, is simply to do Load test or to multi-functional, intelligent analysis; 4) load box power component performance is good, long time, not temperature, redness phenomenon. And better thermal stability, temperature resistance have little impact. 5) See the load is not controlled manually or intelligent control, load boxes now are turning intelligent control; 6) See load box is a constant power or constant resistance, constant resistance load box the result will be error; 7) See load ever had, undervoltage, phase protection; 8) See load box is not solid state relay control off, weak control the strong electricity. 8) See separate three-phase load box is not loaded, if the three-phase balanced load phase imbalance can not be tested; 9) to see how much the minimum step load, the most accurate load box load box to Mao single with minimum step is 0.1KW, most of the other single-phase 1KW, 5KW; and 10) to see there is no load electricity quality parameters display that can show what parameters, dynamic parameters can not be calculated steady-state voltage regulation rate; 11) There are no data storage and reporting functions; 12) the load weight and volume.
