7.3 Heat/power dissipation
For drives with single ended interface circuits, typical operating power dissipation is 11 watts (37.5 BTUs
per hour) of DC power average at nominal voltages. Typical power dissipation under idle conditions is 9
watts (30.8 BTUs per hour).
For drives having differential interface circuits, typical operating power dissipation is 13 watts (44 BTUs per
hour) of DC power average at nominal voltages. Typical power dissipation under idle conditions is 10 watts
(34.2 BTUs per hour).
