Wide range of applications 3.4 inch color screen. Instruction form: paste the QR code of the fan center, the code on the mobile phone to the electronic tutorial Chinese and English interface can be switched. Working mode: four modes CC-constant current mode CV-constant voltage mode -constant power mode -constant resistance mode DTL150 is a DC digital electronic load, equipped with a 2.4-inch TFT color screen, with a maximum power of 150W and a maximum carrying current of 20A. It has four working modes: constant current, constant voltage, constant power and constant resistance; it can be set to voltage, current, and power over Limit protection; set the stop discharge voltage and discharge time; monitor the temperature of the power supply through an external NTC sensor. The product uses a 12V1A power supply to work, is equipped with an alloy integrated silent (203dBA) radiator, and the intelligent temperature control system controls the radiator fan to work. Compared with the analog electronic load, DTL150 adopts the mode of protection first and then working to control discharge, which can effectively protect the discharge power supply and avoid power supply damage caused by over-limit and over-discharge. DTL150 adopts the four-wire connection , the voltage measurement is not affected by the voltage drop of the wire, which makes the voltage measurement more accurate, and the four-wire system is backward compatible with the two-wire connection . Can be shorted separately. Plug Type: US Plug, it applies to Canada, , Mexico, Thailand, Taiwan, the , the Philippines and so on. Plug Type :EU Plug,it applies to Indonesia, , , , and so on.
