Structural Characteristics
1. The internal resistance of the load device is composed of wound resistors or stainless steel sheet or metal tube resistors through series and parallel connections.
2. The load cabinet is made of steel structure, with strong impact resistance. The surface is made by high-temperature spraying. The top can be designed as a ventilation hood or a mesh cover according to the usage conditions.
3. The load test can be designed as forced air cooling or natural cooling according to the on-site requirements, and can be matched with fan monitoring, temperature alarm lights and other auxiliary functions.
4. According to customer needs, a multi-functional current and voltage meter can be installed, providing 485 communication interface, PLC control, industrial control computer, console, etc. accessories.
5. According to different power, it can be designed as portable load, multi-position pulley-driven load, remote control load of the console, etc.
6. When using metal tube resistors to design the load, the risks brought by the thermal expansion and contraction of the metal tube are fully considered, and a telescopic structure is designed to increase the service life.
7. According to customer needs, different industrial control machine interfaces can be customized to meet different customer requirements.
