Features:

Control mode: button control or switch switching. Manufactured with stainless steel alloy resistors, the test process will not cause thermal drift of the impedance value due to the heating of the resistive load element. According to the performance parameters and testing requirements, the user can set and adjust the discharge power, set the discharge time, and the timing time to automatically shut down the load. Detect the working efficiency, full-scale output power and load capacity of various power generation equipment and discharge equipment. Simulate all kinds of complex working environments, sudden increase and unloading of power, and detect the actual load capacity and efficiency of discharge equipment. Emergency stop and temperature protection, overload, short circuit, over-temperature equipment automatic cut-off; ◇It has the function of over-temperature protection and temperature setting (0~100°) and temperature monitoring. Introduction of alloy resistance wire materials: The alloy resistance wire material is selected (working temperature does not exceed 1300 °C), electrical, and the temperature drift coefficient is small (5*10-5/°C) Yinming alloy (NiCr6023). The material of each component of the power dissipation resistor is strictly regulated, the pipe body is made of stainless steel 321 (1Cr18Ni9Ti) with high ductility and oxidation resistance, the filling material is export-grade electrical crystallization oxidation (Sg-9), the implementation standard is JBY-TE4088-199, and the magnesia density value in the manufacturing process is 3. Og/cm3 ±2' The wiring screws and fixing screws are made of stainless steel 304 (0Cr18Ni9). Through a rigorous, unambiguous 3. The OG/CM3 2 material control can ensure that the alloy resistors produced by Batch Star have highly consistent performance. The heat sink is made of stainless steel 321 material with a height of 7mm soil 2 and a thickness of 0.4mm soil 2, and the heat sink is wound at a distance of small 1,000 or equal to 3mm soil 2. The withstand voltage of a single power dissipation resistor is DC3000V or AC1500V, and it does not break down for 1 minute at 50Hz. Through the series connection of multiple alloy resistors, the withstand voltage value can be guaranteed to reach 40kV. The average temperature of the heat sink ≤ 300 °C under normal working conditions, and it does not exceed 320 °C, and there is a margin of nearly 5 times from the resistance to the high temperature of 1300 °C, so as to ensure that the alloy resistor can work continuously for a long time. When the power resistance reaches 300°-400°, the temperature drift is still ≤±2%, so as to ensure that the load resistance value will not fluctuate greatly at high temperature, and the stable power value can be loaded no matter what temperature. Regardless of cold or hot state, the load error is ≤±3%.
