WARNING: DO NOT input any voltages above 10 V DC or 10 kΩ resistance or below 0 V DC 
to any of the 25 pins. Doing so will damage the power supply. The inputs also 
do not have reverse polarity protection. Check your positive and negative 
connections carefully first before feeding power into the control pins. 
Control Output State 
The output state of the power supply can be controlled by EXT_ON (pin 14) and DGND (pin 1). 
Output ON State - Pin 14 and Pin 1 are connected/shorted together. 
Output OFF State - Pin 14 and Pin 1 are opened and not connected together. 
Emergency Shut Off 
In the case where an emergency shut off to the output of the power supply is required, 
SHUT_OFF (pin 15) and DGND (pin 1) is used. 
To shut off, connect/short Pin 15 and Pin 1 to gethe r. This will bypass the analog control of the 
output state and disable (OFF) the output. In this case, pin 14 and pin 1 will need to be 
disconnected/opened from each other and reconnected to enable output again.
