Internal heat load can be deteremined by measuring the difference in temperatrues between the inside and outside of the sealed enclosure with no fans running and all components operating at full power. It is imperative that no ambient air is allowed to pass through the inside of the enclosure.
Watts of heat load can be determined using the voltage, amps and efficiency of main components in the enclosure. If efficiency is unknown, enter 0%.
Watts of heat load can be determined from popular industrial automation components. enter below key components inside the cnclosure. Model assumes 97% efficiency for VFD and 95% efficiency for servo drive and transformer.
