24 V DC ControlLogix power supply
The Allen 1756-PB72 is a new ControlLogix power supply that converts a 24 V DC source into regulated back-plane power. It accepts an input range of 18 to 32 V DC and delivers 75 W at 60 °C while drawing 95 W from the source. Maximum inrush current reaches 30 A during start-up.
Industrial users needing 75 W at 24 V DC
This unit suits ControlLogix chassis that require a 75 W, 24 V DC supply operating up to 60 °C. It is not for systems that need AC input, higher wattage, a different voltage rail, or a lower inrush current than 30 A.
75 W output at 60 °C
The decisive specification is the 75 W continuous output rating at 60 °C. If the chassis load exceeds this figure or the ambient temperature goes higher, a different supply must be chosen.

คำถามเกี่ยวกับสินค้านี้
How do I decide between the 1756-PB72 and other ControlLogix power supplies?
The 1756-PB72 delivers 75 W at 60 °C from a 24 V DC input that accepts 18-32 V. Compare that output rating with the wattage your chassis and modules require.
What does the 75 W rating mean once the unit is installed in a chassis?
It guarantees 75 W of 24 V DC power for I/O and processor modules at up to 60 °C ambient, with 95 W drawn from the source and a 30 A inrush peak at turn-on.
What does the 18-32 V DC input range cap in practice?
The supply regulates a steady 75 W output across the full 18-32 V window, so voltage sag or rise within that band will not reduce available power to the backplane.
