The Hi-Wattage model is standard.  The wattage's stated are based on heavy current connections with unconfined mounting.  The case temperature should not exceed 140 degrees F (60 degrees C).  Additionally the Finned Models require 150 cubic feet(4.2 cubicmeters) per minute air flow over their cases.  The ambient temperature should not exceed 86 degrees F (30 degrees C).  Operation above this temperature the wattage rating should be derated accordingly.

Ordering Information

When ordering specify model number, wattage, output connector and tolerance.
