PSCP
Linear actuators PSL-AMS 2 kN - 25 kN
with Power Fail-Safe Device PSCP
Most industrial facilities are not equipped with secondary electrical circuits and emergency power
supplies. Blackouts as they frequently occurred in recent years do not only mean a loss of productivity but also a loss of control. If the production in the process industry and in some processes of
discrete manufacturing stops without control, that may spoil the complete production batch. Failures
in cooling or heating supplies may disrupt all work ows in utility systems. And they may evoke dangers for employees or environment.

Mode of functioning
The capacitor-based energy strorage is powerful and
maintenance free. As soon as the actuator‘s electronics
recognises a main power failure, it instantly switches its
own PSCP energy pack and the actuator moves towards
the valve‘s preset safety position. This happens safely
with preset thrust or torque and speed. A potential-free
relay contact is available that delivers the information about emergency positioning to the control room.
The PSCP is designed for above 500.000 load cycles.
Benets
• Maintenance-free operation without the familiar
battery „memory effect“
• Calculated lifetime of more than 15 years if operated below
50°C
• High number of life cycles and load capability due to
a low internal resistance, full force is available at all times
• Very good tolerance to low temperature
• Recharging within a few minutes without losing capacity,
therefore the actuator is quickly made ready for a new
emergency cycle
A PSL-AMS is compact and modular
The PSL-AMS linear acutators from PS Automation are available for forces from
1 kN to 25 kN. They are mature and proven,
robust and completely maintenance free.
A PSL-AMS is installed fast and is programmable due to the local control with display, alternatively via the USB-interface.
The automated one-key commissioning is standard.
