KEY FEATURES

Model
UTP3305-II

FEATURES

Parallel mode

When both the upper button and the lower button are “on”, it enters the parallel mode. The positive pole of CH1 is the parallel positive output terminal, and the negative pole 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

Series mode

When the upper button is “on” and the lower button is “off”, it enters the series mode. The output voltage is output from the positive electrode of CH1 and the negative electrode of CH2. The voltage and current value of the series mode can only be adjusted through CH1, and the total voltage value is equal to two of CH1. Times, the current value is equal to the current of CH1.
