Issue
Goal: Example calculation to determine the heat dissipation of a Magelis XBTGT5230 based on the VA rating of the unit.

Product Line
Magelis XBTGT

Resolution
Facts:

• 1 Watt equals to 3.412 BTU/Hr.
• Power Factor of the Magelis XBT-GT5230 is almost one. But for heat dissipation calculation we will use 0.8
• XBTGT5230 Power Consumption: 26VA

To calculate the heat dissipation, you need to consider the type of load you are dealing with. Typically, if you have a capacitive or inductive load, you will need to know the power factor (PF) to convert to Watts:

Watts = VA * PF
VA = Watts/PF
VA = 26/0.8 = 32
.
32 Watts is about 110 BTU/hr.

Therefore, the heat dissipation on a Magelis XBTGT5230 is 110 BTU/hr. Please choose an electrical enclosure accordingly.
