How can I calculate the heat dissipation on a Magelis XBT-GT5230 from the VA rating on the unit?
Issue
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.
