1.Module properties: the isolation booster module.
2.The input voltage: 3-34 V.
3.Output voltage: continuous adjustable (4-35 V).
4.Output current: 2.5 A (MAX).
5.The input current: 3 A (MAX).
6.Input methods: IN + input is level, IN-input negative.
7.Output way: OUT + output is level, OUT-output negative.
8.Adjust way: first correct by input power supply (3-34 V, between) again using a multimeter to monitoring output voltage and the potentiometer (turn step-down, in reverse chronological tur n boost).
9.Output voltage: 4-35 V continuous adjustable (the construction no-load commissioning) our default shipping voltage 12 V if you require other voltage can tune ourselves.
10.Size: 5cm x 2.5cm
