Features:Backlight control, you can turn off or turn on the backlight by short pressing the buttonSeparate wiring terminals independently, simple wiring, no mutual interferenceNo screw elastic connection, tightly pressed, no damage to the LCDStrong and weak current circuit board, strong anti-interfe..
If you need only the CT, please check this: >>>HereMany buyers are response:
Why test data is wrong? Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?
Answer: There are three types of power:
Active Power (P represents / unit W)
● Short press button to switch the backlight on and off.
● Press and hold for 3 seconds to enter the overload power setting.
-- Enter the overload power setting, default value is 4.4KW.
-- The highest bit flash, Short press the key corresponding to the val..
Features:1. The motor can be controlled arbitrarily through the button, normally open, normally closed, inching, forward, reverse, speed control, etc.2. Using imported chips, the governor runs stably and reliably.3. The potentiometer knob can change the duty cycle of the governor output, thereby cha..
