Description
Negative output voltage signal. It is for local sense and certain
function reference; it cannot be connected directly to the load.
Connection for output voltage programming. (Note)
Connection for constant current level programming. (Note)
Differential digital signal for parallel control. (Note)
Note: Non-isolated signal, referenced to [-V(Signal)].

The unit can turn the output ON/OFF by dry contact between
Remote ON/OFF and +5-AUX.(Note)
Short (4.5 ~ 5.5V) : Power ON ; Open(0 ~ 0.5V) : Power OFF ;
The maximum input voltage is 5.5V
High (3.5 ~ 5.5V) : When the internal temperature exceeds
the limit of temperature alarm.
Low (-0.5 ~ 0.5V) : When the internal temperature is normal.
The maximum sourcing current is 10mA and only for output.(Note)
The maximum sourcing current is 10mA and only for output.(Note)
The maximum sourcing current is 10mA and only for output.(Note)
The maximum sourcing current is 10mA and only for output.(Note)
Auxiliary voltage output, 4.5~5.5V, referenced to GND-AUX
(pin 4,6,8,10,17,18) only for Remote ON/OFF used. This output
is not controlled by the Remote ON/OFF control.
High(3.5~5.5V):When the fan fail.
Low(-0.5~0.5V):When the fan works normally.
High(3.5 ~ 5.5V) : When Vout 80% 6%.

Auxiliary voltage output, 11.4~12.6V, referenced to
GND-AUX (pin17 & 18).
The maximum load current is 1A. This output is not controlled
by “Remote ON-OFF”.
Auxiliary voltage output GND.
The signal return is isolated from the output terV & -V).
Note: Isolated signal, referenced to (GND-AUX).
