Power amplifier for proportional valves | Schuhmacher-Tech Hydraulik
The power amplifier PAM-140-P was specially developed for the precise control of proportional valves with solenoids and offers a compact and cost-effective solution for numerous applications in hydraulic systems. Built into a robust IP 65 housing, the PAM-140-P is also suitable for harsh environments and guarantees a high level of reliability.
The device is designed for a typical input signal of 0 to 10 V, but can optionally also be operated with a signal of 4 to 20 mA. Thanks to its regulated output current supply , the power amplifier remains stable and reliable regardless and magnetic resistance , the power amplifier remains stable and reliable .
Flexible parameterisation and simple integration
Parameterisation of the power amplifier is particularly user-friendly. It can be parameterised either via the integrated operating elements or via a digital PC interface in combination with the ULA-310 programming adapter. This flexible configuration of the power output stage makes it easy to adapt the power amplifier to proportional valves from different manufacturers, making it a versatile solution. In addition, the PAM-140-P supports digital control, which facilitates integration into modern hydraulic systems.
Integrated fault monitoring for maximum safety
An outstanding feature of the PAM-140-P is its comprehensive error monitoring. The power amplifier continuously monitors the input signal and automatically switches off the output if the signal exceeds or falls below the specified range. In addition, both the input and output sides are checked for cable breaks. This enables the early detection of defective coils and helps to extend the service life of your entire hydraulic system.
Customised solutions and expansion options
As the official general agent of WEST Elektronik GmbH, we offer customised solutions for customers in southern Germany, Austria and Switzerland. One example of this is the customisation of the PAM-140-P-A power amplifier, which was supplied to a customer with a pre-assembled input cable with an M12 socket and an output cable with a valve connector. Thanks to the preset values for I-MIN and I-MAX, the customer received a completely ready-to-use product based on the “plug-and-play” principle.
For special requirements , we also offer the PAM-199, another versatile power amplifier for proportional valves, which can also be parameterised via a digital interface can also be parameterised via a digital interface and is used in demanding hydraulic applications.
