DC Intelligent load box (Main features and functions) 1, the test parameters: measure voltage, current, power and other basic functions. 2, communications bus: CAN bus with real-time power control system acceptable regulatory signals, fast response. 3, automatic control: The system has automatic loading function, gradual loading from no load to 25% of rated load, 50%, 75%, 100%, and then load this classification progressively reduced from 100 percent load; (software optional) 4, load indicator: with a corresponding indicator light, fault indicator on the front panel, allowing users to work status of the device at a glance. 5, PC software features: ① fan starts, set loading and unloading, and the detection voltage, current, power and other basic functions. ② phase load function, can be 25%, 50%, 75%, 100% phase load, the percentage can be independently set, load time can be set arbitrarily. ③ PC monitoring function: PC with real-time monitoring capabilities, real-time parameters can be saved, no matter which way through loaded, can collect all the data, and generate a variety of curve tables, or direct printing. (Software optional) 6, the data save interval: Steady Data minimum resolution time is 2S, transient data minimum resolution time is 40US. (Software optional) 7, protection function: protection features temperature detection protection, overvoltage protection, overcurrent protection, if an exception host immediately cut off the load, to protect the power supply and the load equipment. 8. Emergency stop: loaded with emergency stop function, to ensure that equipment in a particular situation, it may unload, ensure the safety of the device and the power supply. 9, intelligent design: intelligent control, automatic test power various parameters. The power supply provides a scientific means of detection. 10, power components and cooling section (resistive load): A new power components, thermal resistance and seal mounted in a stainless steel tube, external heat sink pipe with insulation, moisture-proof, corrosion resistance, heat resistance, high insulation safe and reliable. Resistive element power density, three-phase current balance, no red-hot phenomenon, independent cooling fan, ensures heat dissipation and life of the entire system. The load overcomes the water resistance test system can not accurately control the size of the resistance, boiling water is easy, easy to scale; difficult to control and so on. Water resistance of the upgrading of products, the product safety, low maintenance costs. Low noise, strong overload.
