Power Dissipation
ULTRA 100 Series drives dissipate power that results in cabinet
heating. The following table lists power dissipation values. Calculate
the cabinet cooling requirements using the power dissipation
information and formulas below.
Maximum power losses are shown to help size a NEMA 12 or
equivalent enclosure and to ensure the required ventilation. Typical
power losses are about one-half maximum power losses.
When sizing an enclosure with no active method of heat dissipation,
the following equation approximates the size of enclosure necessary:
