Ambient Operating Temperatures
The Diode Bus Supply is designed to operate at 0…40 °C (32…104 °F)
ambient without derating. Remove the label from the top to operate the
Diode Bus Supply in ambients 41 °C up to 50 °C (104 °F up to 122 °F).
Important:Removing the adhesive label changes the enclosure rating from
NEMA Type 1 Enclosed to Open Type. This also changes the
side-to-side mounting clearance requirement.
Ensure that proper cooling is provided to the Diode Bus Supply to stay
under the 40 °C rated specification. Add exhaust fans to the front or top of
the enclosure bay and provide a filtered opening at the bottom of the cabinet
bay.
The Diode Bus Supply watt loss (from specification section) is 500 W at
120 A. The three-phase AC line reactor watt losses are listed in the 1321
Power Conditioning Products Technical Data, publication 1321-TD001
.
It is recommended that the system integrator completes a thermal evaluation
to ensure adequate cooling to maintain proper operating conditions for each
cabinet or bay.
