OUTPUT POWER - AMBIENT TEMPERATURE(DERATING)
• If the case temperature is used for the derating, apply the range indicated
by the dashed line.
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.
PRECAUTIONS
• Parallel operation to increase output current is not possible.
• Since the converter is entirely shielded by a metal case, care
should be taken to isolate the case from the surrounding compo-
nents and wiring pattern.
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.
