Can meet most of experiments needs.
Note:
1. According to the output power requirements, please select input power with a sufficient output current, or it may not start. Output power = output voltage from various quarters * total output current, input power should be at least> Output power /0.9. For example, a standard power supply 5V, 1A, and to power the unit, it can provide up to about 4.5W of output power.
2. The total output power of machine should not exceed 10W, when single output, can provide short-term high current, but this time must pay attention to the heat sink temperature, not too high so as not to damage the IC. If you do not have experience, please control the output current of each channel to less than 0.2A. Excessively large output current may cause damage to the IC overheat.
3. Each output of the IC have protection, but please avoid a short circuit, all output wiring connections should be completed and then turn on the power.
