Enable (ENA)
The Enable signal is pulled up to the AUX by a 10
kΩ external resistor, indicated by an LED. The
recommended circuit diagram of Enable is shown
in Figure 32.

CNT (On/Off)
The CNT (On/Off) pin provides the remote control
function without turning the input power supply on
or off. When the remote control function is not
required, short-circuit CNT and COM.
The logic of On/Off is as follows.

Negative Low level
Logic
High level or left open
The configuration diagram of CNT (On/Off) is as
follows.

Auxiliary Power Supply (AUX)
The AUX pin supplies auxiliary power to an
external circuit with a typical output voltage of 12 V.
Be careful not to short-circuit the AUX pin and
other pins on the module; otherwise, the module
will be damaged. Do not connect the AUX pin if
power supply to an external circuit is not required.
Parallel Operation (CB)
When several modules are used in parallel, an
output current can be equally drawn from each
module by connecting the CB pins of all modules.
A maximum of two modules can be connected.
The output power of two modules connected in
parallel is equal to or less than 90% of the power
of two fully loaded modules.
