SKF's VCU can be used with a combination of telescopic pillars, rotary actuators and linear actuators in a wide variety of industrial and mobile applications.
SKF has released a low-cost Versatile Control Unit (VCU), designed to control up to five actuators at any one time.
The VCU can be used with a combination of telescopic pillars, rotary actuators and linear actuators in a wide variety of industrial and mobile applications.
Quick and simple to install, the VCU incorporates a number of integral safety features, which offer exceptional end user protection and extend service life considerably.
The internal configuration of the VCU improves performance and simplifies cabling and power arrangements.
Compact and reliable, the unit delivers a 24V DC feed to each actuator, using standard DIN8 plugs, from a mains supply or battery pack.
The new unit can also be used with high-power actuators, with up to 10A per channel and also features two external limit switches to allow sequential control of actuator movement, while separate control facilities are available for hand, foot or other remote operating devices via standard HD15 connections.
The VCU incorporates several failsafe mechanisms, ensuring protection against actuator overload in both directions and preventing overheating by means of a thermal switch.
The detection of mechanical errors or short circuits in the event of a power surge will automatically initiate shutdown of actuator movement, providing exceptional end user safety.
In addition, a relay circuit eliminates potential problems caused by contact corrosion resulting from arcs, which extend service life still further.
The VCU is compatible with a wide range of SKF actuators including the Runner, Ecomag, CAT and Care series.
The Runner series, in particular, features push force capacities of up to 12,000N and operating speeds of up to 7.5mm per second under full load conditions.
