Attention:

This is a DC-DC voltage converter module, use must pay attention to:

1 The input voltage cannot be greater than the maximum input range

2 The output power cannot exceed the maximum load for a long time

3 The input power must be greater than the output power because of the power consumption of the module itself

Question and answer:

Q1: Why is the output voltage lower than the nominal voltage

The maximum output power can be up to 8W, but the maximum power will be different under different conditions. Please refer to the following table for details (10-80% of the maximum power is most reliable) :

Input DC 3-24V, output ±5V

The input voltage: 3 V / 3.3 V / 3.7 V / 5 V/V / 6 to 9 15 V/V / 12 V / 18 V

Maximum output current: 0.1-0.8A

Input DC 3-24V, output ±6V

The input voltage: 3 V / 3.3 V / 3.7 V / 5 V/V / 6 to 9 15 V/V / 12 V / 18 V

Maximum output current: 0.1-0.7A

Input DC 3-24V, output ±9V

The input voltage: 3 V / 3.3 V / 3.7 V / 5 V/V / 6 to 9 15 V/V / 12 V / 18 V

Maximum output current: 0.04-0.6A

Input DC 3-24V, output ±10V

The input voltage: 3 V / 3.3 V / 3.7 V / 5 V/V / 6 to 9 15 V/V / 12 V / 18 V

Maximum output current: 0.03-0.55A

Input DC 3-24V, output ±12V

The input voltage: 3 V / 3.3 V / 3.7 V / 5 V/V / 6 to 9 15 V/V / 12 V / 18 V

Maximum output current: 0.03-0.46A

Input DC 3.3-24V, output ±15V

The input voltage: 3.3 V / 3.7 V / 5 V/V / 6 to 9 15 V/V / 12 V / 18 V

Maximum output current: 0.03-0.41A

Input DC 3.7-24V, output ±18V

The input voltage: 3.7 V / 5 V/V / 6 to 9 15 V/V / 12 V / 18 V

Maximum output current: 0.04-0.31A

Input DC 3.7-24V, output ±24V

The input voltage: 3.7 V / 5 V/V / 6 to 9 15 V/V / 12 V / 18 V

Maximum output current: 0.03-0.25A

A1: The input power is too low. Use a to test the input voltage. The input voltage is low

Q2: Why not output negative voltage or output too low?

A2: Negative voltage cannot be used alone. When using negative voltage, the same load must be connected at the positive voltage end.
