◆ made of stainless steel alloy resistors。
◆ the discharge power can be set according to the power detection requirements, and can be put in a combination of buttons。
◆ detect the working efficiency of various power generation equipment and discharge equipment, the maximum output power and load capacity of full load operation。
◆ simulate various complex working environments, sudden increase and unload of power, and detect the actual loading capacity and efficiency of the discharge equipment。
◆ the use of precise and high-precision load materials can truly simulate the actual load's loading force and the ability to adapt to slight changes in the load。
◆ emergency stop and temperature protection, overload, short circuit, over-temperature equipment automatically cut off。
◆ upper limit and lower limit voltage setting, automatically drop to the range voltage point according to the energy (limited program control machine)。
◆ temperature protection setting, temperature 0~100° can be set, and real-time temperature condition can be detected at the same time。
◆ programmable interface 0~30 groups of power and current can be set arbitrarily, the minimum execution time is 1ms and can be cycled 999999 times (limited to program-controlled machine)。
◆ the minimum resolution of the load is 1w, which can accurately simulate the power generation or on-off capability of the product。
◆ it is possible to upload the measurement data to the computer and realize the process record and storage function of the detection process data (only programmable controller)。
◆ there are two operation modes: panel operation or remote control (program-controlled machine only)。
◆ with over-temperature protection function, temperature setting and temperature monitoring。
◆ different time constant loads can be customized。
◆ used in generators, ups, switches, fuses, electrical accessories, transformers, temperature rise tests, low-voltage electrical factory inspection, production debugging, simulation of harsh loads，accurate testing sites for environment, scientific research and development, military industry, etc。
◆ use button control or switch switch (touch screen control with rs232 communication interface)。
◆ can measure voltage, current, power。
