Fail Safe Solutions for Actuation by ProMation Engineering

The PBU series of computer-grade Uninterruptible Power Supply (UPS) back-up systems designed for use with ProMation Engineering P Series electric industrial quarter-turn actuators provides the power necessary to drive actuators to a field selectable fail-safe position. Full customization is available with use other actuation products.

• Computer-Grade UPS Back-Up Systems
• Field Selectable Fail Direction
• Readily available sealed Battery packs
• Provides 500% of Power requirements for a full load cycle
• Lockable Fiberglass NEMA 4X enclosure
• Simple User Interface with Indication Lights

Application:

Typically, applications requiring fail-safe operation of actuated devices have had to rely on either the limited power of mechanical spring return actuators, or use costly high pressure pneumatic devices to provide fail-safe positioning. Model PBU series computer-grade UPS back-up systems designed for use with ProMation Engineering P Series electric industrial quarter-turn actuators provides the power necessary to drive these actuators to a field selectable fail-safe position. The system consists of a NEMA 4X control cabinet with lockable hinged door housing the logic switching, all field wiring terminal points and a computer-grade back-up system. The back-up system utilizes a replaceable spill-proof battery pack that can be readily purchased at most office-supply centers.

Safety in Numbers:
The system is designed to provide at a minimum up to 500% of the power required to drive the various actuators through their full 90 degree rotation at full running amperage draws. However, when the actuators have reached their field-selectable end-of-travel positions, current draw drops to zero and the back-up system sits idle until either the time-out function integral to the battery is reached or the mains power returns, whichever occurs first.

Simple User Interface:
Indicator lights visible through the front of the control cabinet give status indication of mains power, back-up system charging and failsafe operation. The PBU series is powered from building power, and all power and logic interface wiring passes through the control cabinet. Units are selected based on the size and number of P Series actuators being connected to the PBU system. Each model can be utilized for multiple control schemes...On/Off, Jog or Proportional control... to provide the most cost-effective and efficient means of providing fail-safe operation for these actuators.
