set2: 1 x 600W boost constant current module + 1 x Amplifier Board Small size design, BTL output, the maximum output 100w, can drive 2 ohm speakers, be balanced (differential) input, external heat sink chip work more stable. Signal input mode can be selected according to the following two needs: Balanced input signal (differential): Signal + Signal -, GND (ground). Unbalanced inputs (single-ended): - end and GND (ground) short circuit, the signal input from the + terminal. 3300 / 25V filter capacitor The output voltage regulation: 1. adjust the CV-ADJ potentiometer, according to your or LED, the output voltage is set to the voltage you need. Clockwise voltage is small, counterclockwise adjustable. 2. clockwise CC-ADJ potentiometer about 20 laps, the output current is set to a minimum, connected to the LED, CC-ADJ potentiometer to the required current. For charg, put the after the end of the, then receive the output, adjust the CC-ADJ to the current you need, (for charg must be used when the is fully charged, because the left The more charge, the smaller the charge current.
