DataSheet 40W, Triple Output Output Over Voltage Protection The output over-voltage protection consists of an output Zener diode that monitors the voltage on the output terminals. If the voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode clamps the output voltage. Short Circuit Protection Continuous, hiccup and auto-recovery mode. During a short circuit the converter shuts down. The average current during this condition will be very low.

DataSheet 40W, Triple Output Heat Sink Consideration All dimensions in millimeters Use heat-sink (7G-0026A) for lowering temperature and higher reliability of the module.
PAGE 36
DataSheet 40W, Triple Output Remote ON/OFF Control The Remote ON/OFF Pin is used to turn on and off the DC-DC converter. The user must use a switch to control the logic voltage (high or low level ) of the ON /OFF pin, referenced to Vi (-). The switch can be a open collector transistor, FET, or Opto-Coupler, that is capable of sinking up to 0.5 mA at a low-level logic Voltage. For high-level logic of the ON/OFF signal (maximum voltage): the allowable leakage current of the switch at 12V is 0.5 mA.

DataSheet 40W, Triple Output Safety and Installation Instructions Fusing Consideration Caution: This converter is not internally fused. An input line fuse must always be used. This encapsulated converter can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. For maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse.
