AC890PX AC Drive
Auxiliary Power Supply Requirements
This tables lists the auxiliary power supply (nominal 24Vdc) requirements for the AC890PX and ancillary equipment, assuming normal operating conditions with maximum
SMPS and fan loads. This auxiliary power supply is used during configuration without the need for mains supply.

Worked Examples
To calculate the total requirement for an AC890PX fitted with a 6911 keypad:
Power = 30 + 1 = 31W, Input Current @ +24V = 31 / 24 = 1.3A
To calculate the total requirement for an AC890PX fitted with a 6901 keypad and Profibus Tech Card:
Power = 30 + 1 + 2.3 = 33.3W, Input Current @ +24V = 33.3 / 24 = 1.4A
IMPORTANT
The AC890PX's in24V SMPS has a 4A current limit which is used during start-up.
For example, the initial loading will be 4A for approximately 50ms during start-up. Consequently, the customer auxiliary SMPS +24V
power supply must be able to over-load for a brief time to accommodate the start-up condition.
