NV12V012-MF Three-way controller
Is one of well-developed multichannel of output solar recharge controller,
providing system voltage of multichannel output, facilitate more load use;
At the same time also provides three road 300mA 12 v/ 9V / 6V (or 12 v / 6V / 3V) respectively.
More paragraphs voltage source output. Used for load such as walkman.
A, function:
According to the battery voltage level, adjust charging electric current, and decide whether to load power supply,
achieve the following goals:
1. Often keep the battery voltage in full status.
2. Prevent battery charging excessive.
3. Prevent battery excessive discharge.
4. Prevent nighttime battery to solar panels reverse charge.
B, load switch choice:
There are control switches in every way load fan-out respectively: L1 and L2, L3 and multi-range voltage source control switch L4.
control the output of every road respectively,
when the switch is open, whether to supply power is up to internal undervoltage circuit.
C, connection: (as below)
1. Connect battery "+" and "-" pole to corresponding terminal of controller correct firmly (from left 3, 4).
2. Connect solar panels "+" and "-" pole to corresponding terminal of controller correct firmly (left 1, 2).
3. Connect load "+" and "-" pole to corresponding terminal group of controller correct firmly (from left first group of 5, 6; the second group 7, 8;9, 10 of third group).
4. Plug battery socket of load as walkman etc to the corresponding voltage the socket on the back of the controller (respectively for 12V / 9V / 6V or 12V / 6V / 3V), and ensuring that each group load current is not more than 300mA.
D, note:
1. Please check carefully before connection and confirm that the rated voltage of solar panels, batteries, load should be the same, and are the 12V (or 24V).
2. Rated current of the solar panels, load should not be more than controller rated current (10A).
3. Please do not connect the battery polarity inversely, or the fuse will blowing; if the fuse blowing, please replace the same type of fuse (15A).
