Various All other electrolytic capacitors
See components to be monitored diagrams below.
Higher temperatures limits (in brackets) may be used but product life may be reduced.
Input Connections:
Molex 3 pin header 7A/250V MAX.
IEC 60320 inlet
Output Connections:
Maximum Torque Settings for Output Screw Terminals: M3 – 0.5 – 0.6Nm
Protective Earth Conductor
The Protective Earth conductor has been tested at 40A for 2 minutes through the J2 input connector. Additional
testing may be required in the end use equipment.
Earthing
For uncased models without the global option, Y1 to Y5 must be connected to Protective Earth. For models
with the global option, Y1 to Y7 must be connected to Protective Earth in the end use equipment.
Capacitive Loads
Outputs on NV300 are designed for use with capacitive loads up to the value shown in the table below.
Applications where a discharged capacitor is switched onto the power supply output create additional loading for
which a non standard product may be required.
Consult factory for details.

Note 1 –To calculate the allowed capacitance multiply the figure in the table above by the maximum allowed
current rating of the output.
Note 2. The H applies to outputs identified with an H e.g. 5H is a 5V high current variant.
