UD18L-B 65W Adjustable Constant Current Load Electronic Load For USB DC Voltmeter Ammeter Test

UD18L-B 65W Adjustable Constant Current Load Electronic Load For USB DC Voltmeter Ammeter Test

Description:
High-power, high-voltage, high-current, high-power fine-tuning constant current USB load is compatible with PD fast charging. Users can easily age their fast charging equipment.

With a shell, the load can prevent short-circuit. It is designed with fan guards.

Attention:
Potentiometer Adjustment Method: Turn counterclockwise to decrease current; turn clockwise to increase the current. During use, if your USB voltmeter does not display after plugging in the load, it may be that the load current adjustment is too large and your power supply is insufficient, and it will automatically shut down and no output.Solution: Rotate the current potentiometer counterclockwise to the minimum first, then plug it into power supply,and then slowly turn it up clockwise until the USB voltmeter display goes out. The value at the moment is the maximum output value of your charger power supply.

Features:
- 65W adjustable constant current load is compatible with PD fast charging. It can be used for discharge aging detection, test Type-C and line for Android. It is powerful, portable and multi-functional.
- High power/wide voltage/high current discharge aging. Voltage input: DC5~24.0V, covering almost all high-voltage aging of fast charging protocols. Adjustable current is 0.2~4.8A (the maximum current is controlled within 65W according to the law of conservation of energy by the input voltage, calculated by P=UI) to reach the current allowable range of USB interface. Equipped with a 12000-rpm intelligent temperature-controlled fan + all-aluminum heat sink, power can be continuously aged by 45W, and ultimate aging power is 65W (within 3 minutes), which is a higher technical index in the industry.
- Huge discharge tube makes power more reliable. The discharge tube model is IRFP260N (50A/200V) large package device, and matched with 12000 rpm intelligent temperature control fan + all-aluminum heat sink, making it with compact size and more power.
- Professional devices & precision production. Devices with professional instruments, strong functions. Summarize hundreds of instrument circuit principles and evolutionary extraction. With a high-speed fan and an all-aluminum heat sink, large-package high-current high-voltage discharge field effect tubes, the overall performance of the load is greatly improved, allowing wider using range and longer service life.
- Fan metal protection + bottom plate plastic shell protection. The bottom plate is protected by an open mold plastic shell, which is not easy to short-circuit and is beautiful. A metal protective cover is used on the cooling fan for safety protection, which brings the design technology of USB load to a higher level.
- Three input interfaces meet your diverse needs. In order to cater to the technological update in the charging era, it provides multiple input methods such as USB-A male input/Micro USB female input for Android/Type-C female input, allowing users to more conveniently adapt to various aging discharge needs
- Multi-turn precision adjustable potentiometer with handle. The load adopts the multi-turn precision adjustable potentiometer with full copper handle. Current adjustment is finer and aging power is finer. When used with other ammeters, a finer current value can be obtained to meet measurement needs.
- Detect Type-C/data cable for Android: Make an U meter connected according to the picture, it can easily detect overcurrent, quality and charging performance of the Type-C or installed data cable. Test method: After connecting power supply as shown in the figure below, first manually turn off the load through the toggle switch button of the load and record no-load voltage on the U meter. Then turn on the load and adjust current potentiometer knob to increase/decrease the current to make the voltage on the U meter compared with the no-load voltage. The current when the voltage is reduced at 0.5~1V is the rated current value that this line can pass (different voltage drop standard values will get different currents, and the voltage reduction standards are different according to your line length). Test data cable for Android also takes the same operation (you need to purchase a UD18 color screen meter separately).
- Various mobile power discharge detection: It can be matched with a tester to detect the discharge of power banks, adjust the potentiometer knob, detect the capacity value of the power bank, and easily detect the discharge of various power banks. The operation is simple, convenient and fast.
- Aging test of various chargers: First turn the potentiometer knob of the load to the end in a counterclockwise direction, then insert a USB interface device such as a power bank/charger, and then use your finger to slowly adjust the knob clockwise to perform discharge aging detection, so that the charger can be used for a long time with load, check the stability of the charger. (Need to purchase T18 color screen meter separately)
- Small size: The 65W high-power constant-current load adopts ergonomic design, which is comfortable in hand and moderate in size. A variety of functions are integrated in one body, and the body is compact, and it is really convenient to carry.
