Product catalog summary

Introduction
This document outlines the technical specifications and benefits of various control units used in actuator systems, including BCU, VCU, SCU, MCU, and COMPACT. Each unit is designed for specific applications and offers unique features.

BCU (Basic Control Unit)
The BCU is a compact 3-channel actuator control unit with features like single fault safety, overload and over-temperature protection, and medical application approval. It operates at 120V AC or 230V AC input and provides a 24V DC output. It is easy to clean and has low standby current.

VCU (Versatile Control Unit)
The VCU is a 5-channel unit, also approved for medical use, offering single fault safety and protection against overload and over-temperature. It supports 120V AC or 230V AC input and provides a 24V DC output. It is designed for easy cleaning and low standby power consumption.

SCU (Superior Control Unit)
The SCU is a 6-channel unit with remote control capabilities via RS232, featuring single fault safety and encoder processing. It is approved for medical applications and operates at 24V DC, 120V AC, or 230V AC input, providing a 24V DC output.

MCU (Mobile Control Unit)
The MCU is designed for mobile applications, featuring LED indication for battery charge level and an audible signal for low charge. It supports two motor ports and operates at 28V DC input, providing a 24V DC output.

COMPACT Control Unit
The COMPACT unit allows synchronized movement of three actuators and supports up to four memory positions. It features a high-efficiency switch-mode power supply and low standby power consumption, operating at 207-254.4V AC (EU) or 90-127V AC (US) input, providing a 24V DC output.

Conclusion
Each control unit is tailored for specific applications, offering features like fault safety, overload protection, and medical standards compatibility. The document includes detailed technical data, such as input/output specifications, duty cycles, and environmental conditions for each unit.
