Reliable BK820A DC Fan Speed Tester for Precise Fan Testing
The BK820A DC Fan Speed Tester is a reliable tool designed for precise fan testing. It features a 7-inch color touch screen with a resolution of 800x480, making it easy to navigate and set parameters. Equipped with a built-in oscilloscope function, it can display current wave and FG signal wave simultaneously, providing detailed analysis.
This tester is equipped with a programmable power supply that allows easy setting of any voltage value. The built-in 0-52V 5A power supply adjusts the voltage automatically to maintain consistency with the set value, even with load changes.
Features and Specifications of BK820A DC Fan Speed Tester
With its easy-to-use design, simply connect the fan to the tester to test the speed. The BK820A supports testing of 2-wire, 3-wire, 4-wire PWM, and brushless fans with FG and RO signals. It also offers the convenience of fan polarity reverse connection and short circuit protection.
The BK820A DC Fan Speed Tester provides comprehensive display options, including speed, current, voltage, and power. It can also function as a program-controlled DC power supply on its own.
Ensure accurate testing with the infrared sensor head, which allows for precise speed measurement without the need for marking the fan. The aluminum alloy shell provides durability, and the overall size of 355x200x155mm offers convenience.
