CONNECTIONS
The input voltage detection output terminal (±Alarm) is a transistor
output of a photo-coupler and it is insulated at the both input and
output sides.
LOW INPUT VOLTAGE DETECTION CIRCUIT
The following circuit configuration is recommended for the low
input voltage detection circuit.
In a rise of the power supply, the +Alarm terminal is at the low level
when the input voltage is in a range of 18 to 19V.
In a fall of the power supply, the +Alarm terminal is at the high level
when the input voltage is in a range of 17 to 18V.
