SAFETY
The converter is certified according to EN60950 (Kema), UL 1950 and CSA 22.2.
The converter has basic insulation rating. The converter meets NEBS compatibility.
An external input fuse must always be used.
ON-OFF CONTROL
The default logic is negative: the on/off (pin #2) voltage is referenced to the -Vin (pin #4) and must be lower than 0.8V to
turn the module on, and higher than 2.7V to shut the module off.
Consult the factory for availability of positive logic modules.
TRIMMING
The output voltage can be trimmed by means of an external resistor connected between the Trim and the
+S or -S pins. The selection of the resistor follows the industry standard.
A resistor connected between Trim and - S pins will decrease the output voltage. For a decrease of
% of the nominal
output voltage, the value of the resistor should be:
Rtrim-down =
k

A resistor connected between Trim and + S pins will increase the output voltage. For a desired increase of
