◆ 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。
