Based on the basic performance characteristics of the DC load box, it is commonly used for regular equipment inspections and maintenance, project acceptance, diesel engine testing and maintenance, and electrical island testing by manufacturers, etc. The power ratings we commonly use vary greatly, with 200KW typically used for UPS and diesel generator testing, while power ratings up to 1000KW are generally used for load supply equipment. Such power supply equipment can be optionally paired with inductive loads or dry-type load boxes, and the range and options for power ratings from 1000KW to 3000KW are also quite similar. For PLC types, they are generally used for testing simulated resonance and inverter island effects, with inductive loads typically at 75KVA and capacitive loads at 75KVAR. The most unique is the resistive load, which is usually 100KW.
