SA 811F 3BDH000013R1

Power Supply 115 / 230 VAC
To use together with PM 802F or PM 803F.
Freelance V7.1SP2a or higher is mandatory.

The AC 800F modules are supplied with 5 VDC / 5.5 A and 3.3 VDC / 6.5 A by SA 811F. The power supply has open-circuit, overload and sustaine short-circuit protection. The electronically controlled output voltage provides high stability and low residual ripple. In case of power loss ≥ 5 ms, the power supply module generates a power-fail signal. This signal is used by the CPU module to shut down operations and enter to a safe state of connected outputs of Remote I/Os. This is required for a controlled restart of the system and the user application when power is restored. The output voltage remains within its tolerance limits for at
least another 15 ms. Altogether a mains voltage drop of 20 ms will be managed.

Features:
• Input voltage 115 – 230 VAC (self adjusting), output is electrically isolated
• Power supply outputs provide: 5 VDC / 5.5 A and 3.3 VDC / 6.5 A
• Enhanced power-fail prediction and shutdown procedures
• LED indication for power supply status and operating status of the AC 800F
• Short circuit proof, current limited
• 20 ms backup energy for use in the event of primary power failure, according to NAMUR
• G3 compliant Z variant available.
