Sample Calculation 2
240-volt,18-amp load, 25 °C ambient air temperature
Model: 240D45
See the last two columns of the table on
the bottom of the table.
Dissipation: 0.9 watts/amp
Thermal resistance: 0.67 °C/watt
Maximum junction temperature: 110 °C
The calculation would be as follows:
Duty Cycle Calculation
When solid-state relays are operated in an on/off mode, it may be advantageous to calculate the RMS value of the current through
the SSR for heat sinking or determining the proper current rating of the SSR for the given application.
