Adjustable Step Down Power Supply (30 V, 10 A)

Overview

This adjustable step down power supply module is basically used to measure the power supply of your projects. The numerical measurement of its input and output voltage are displayed on LED display digits.

The circuit is in a metal casing in order to protect it from electromagnetic fields.

Specifications

• Input voltage: DC3.5～30V (do not overvoltage)
• Output voltage: DC0.8～29V (Note: This board is a step-down board, and the input voltage is required to be 1V or more higher than the output voltage)
• Output current: 10A (MAX)
• Conversion efficiency: 92% (measured when 24V is converted to 12V/2A)
• On-board voltmeter: It can display input voltage or output voltage. Short press the button below the glow tube to switch. The LED light marked IN is on to measure the input voltage, and the LED light marked OUT is on to measure the output voltage.
• The voltmeter can be turned off. Press and hold the switch for more than 1 second and less than 4 seconds, and you can turn it off when you let go.
• The voltage display has been calibrated at the factory, no additional calibration is required. The blue glow tube shows that the quiescent current is 2-8mA (related to whether the glow tube is turned on)
• Dimensions: 85 x 58 x 33 mm
