Description:
Technical parameters:
Circuit board size: 68mm × 50mm
DC input: DC 3-30V
AC input: 3-20V
Output DC: DC 1.25-28V (continuously adjustable)
Maximum current: 2A
Minimum pressure difference between input and output: 3V
Can be connected to loads below 2A, with a continuously adjustable DC output of 1.25V-28V and a wide voltage range for use.
Added digital voltage display function, output voltage is clear at a glance, very suitable for experimental use.
The power supply input must be at least 3V higher than the output to stabilize the voltage. It is a step-down type and cannot be boosted. When inputting 5V, it can output 1.25-2V without outputting a higher voltage.
Attention: Due to the power supply voltage of 3.3V, the digital digital display meter can only display normally when the voltage is higher than 4V. When there is no display on the digital tube, the output voltage can still be reduced to 1.25V. If you need to accurately display voltage below 4V, you can use a multimeter to assist in adjustment.
