The 180W high-power/200V wide voltage/30A high current met various experimental tests. This time, we have greatly improved various aspects and performance, giving players a new experience. 180W power refers to the formula P=UI (power=voltage X current) according to the power calculation formula Product technical parameters Test voltage: 2-200V Working current: 0.2-30A Constant load adjustment rate:+/-3%+3 bytes DL24P discharge power: voltage X currentCut-off voltage (<000.0 ~ 150V), when the voltage is less than the set value voltage (such as <2.0V), the device will stop discharging! Four operating modes Constant current operation（CC） Constant voltage operation（CV） Constant power operation（CP） Constant resistance operation（CR） Voltage accuracy evaluation and precision testing of large-scale professional instruments The precision has been strictly calibrated by engineers before leaving the factory, using patented soft calibration technology and large instruments for calibration Software learning precision, which uses software to repair small errors caused by hardware, enables measurement precision to be exactly the same as that of large instruments Real time display of internal and external dual temperature measurement data, three major intelligent safety protections Equipped with an external wired NTC temperature probe, achieving dual temperature measurement inside and outside. The external temperature can be used to test the temperature of the charging bank, charger, body temperature, water temperature, and more occasions; Internal temperature test load, internal temperature etc At the same time as discharge detection, there are three major intelligent safety protections that monitor the status of discharge tubes in real-time, ensuring safety and reliability! Upgrade to 4-wire system while also compatible with 2-wire system When testing or aging DC power supply products, you can use the simplified 2-wire wiring method A+V+short circuiting, A-V - short circuiting as shown in the first figure. When you need to accurately test the battery capacity, you can use the second 4-wire wiring method shown in the figure below to measure the voltage Not affected by the voltage drop of the current wire, making voltage measurement more accurate and able to accurately determine the battery voltage, accurately stop discharging, and accurately protect the battery and conduct accurate testing of capacity Test the capacity of various mobile power sources to bid farewell to fake power banks Easily test the capacity of various mobile power supplies. First, we will reset the display data to zero, as shown in the connection method shown in the figure, The power bank can be discharged until the power bank is depleted. The capacity mAh value displayed above is multiplied by the ratio of lithium battery to output voltage and power bank efficiency to obtain the nominal capacity value of the power bank ## Features - 4 operating modes: CC-constant current operation; CV-constant voltage operation; CW-constant power operation; CR-constant resistance operation. There are three intelligent safety protections in the discharge detection process, which can monitor the discharge tube status in real time, which is safe and reliable. An external wired NTC thermometer can realize dual temperature measurement inside and outside. - 2.4-inch high-definition large color screen blue digital curve version of high-power electronic tube digital load meter. Intelligent temperature control color glare fan, high power, long life, durable cooling fan; 180W high power / 200V wide voltage / 20A high current, strong performance. - Support testing Android, Type-C cable, Mini and other wires, and display a variety of test data on one screen. By checking and killing, by testing various data cable/charger test/discharge aging/DC power adapter current, voltage, power and other parameters, the operation is simple and the test is convenient and fast. - 180W load discharge aging test, using intelligent temperature control light effect fan design, built-in large discharge tube, the temperature is maintained at about 50~80 degrees; easily test the voltage, current, capacity and other data of various power sources such as lithium batteries/USB chargers; Powerful, safe and reliable. - If there is any abnormality in the product, whether it is return or exchange, you can contact us first, we will reply you within 6 hours, we will be happy to solve it for you, thank you. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B56SP7Y9 | | Best Sellers Rank | #416,318 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #364 in Voltage Testers | | Brand | Vastarry | | Brand Name | Vastarry | | Color | Blue | | Customer Reviews | 3.9 out of 5 stars 57 Reviews | | Manufacturer | Vastarry | | Measurement Type | Voltmeter or Ammeter | | Min.
