Instrumentation

Attention:

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


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

2 The output power cannot be greater than 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


Q&A:

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

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

Input DC 3-24V, output ±5V

Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

Maximum output current: 0.1-0.8A


Input DC 3-24V, output ±6V

Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

Maximum output current: 0.1-0.7A



Input DC 3-24V, output ±9V

Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

Maximum output current: 0.04-0.6A


Input DC 3-24V, output ±10V

Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

Maximum output current: 0.03-0.55A



Input DC 3-24V, output ±12V

Input voltage: 3V/3.3V/3.7V/5V/6V/9V/12V/15V/18V

Maximum output current: 0.03-0.46A


Input DC 3.3-24V, output ±15V

Input voltage: 3.3V/3.7V/5V/6V/9V/12V/15V/18V

Maximum output current: 0.03-0.41A


Input DC 3.7-24V, output ±18V

Input voltage: 3.7V/5V/6V/9V/12V/15V/18V

Maximum output current: 0.04-0.31A


Input DC 3.7-24V, output ±24V

Input voltage: 3.7V/5V/6V/9V/12V/15V/18V

Maximum output current: 0.03-0.25A



A1: The input power is too low. Use a multimeter to test the input voltage, the input voltage is very low at this time

Q2: Why does it not output negative voltage or the output is too low?

A2: Negative voltage cannot be used alone. When using a negative voltage, the same load must be connected to the positive voltage terminal.
