The UTP3300 series are 3-channel linear DC power supplies with low ripple/noise, overload protection and constant voltage/current capabilities.
Parallel mode
When both the upper and lower buttons "light", it enters parallel mode. The positive terminal of CH1 is the parallel positive output terminal, and the negative terminal of CH1 is the parallel negative output terminal. The voltage and current value settings in parallel mode can only be adjusted through CH1. The total voltage value is equal to the voltage value of CH1, and the current value is equal to CH1+CH2
