Estimate Module Supply Power Dissipation and Field Loop Power Dissipation

Module supply voltage and field power consumption is dissipated as heat. Use these

tables to estimate the supply voltage and field power heat dissipation of your system.

Note: All figures given are worst-case estimates based upon maximum operating field

current and voltages.
