HEATING CONTROL UNIT

Control electronics for SMA release actuators

  • Satellite above Earth
  • Satellite in orbit
  • Satellite against a dark background
  • Space station orbiting Earth
  • Space station in orbit
  • Space shuttle in orbit

Key features

Safety barriers

Designed to drive your hardware but also to proctect it. Adjustable maximal temperature, gheating time and rate limit

Mobility

120Wh of battery capacity in small 2kg package. Designed to be used off-grid without PC.

Data and measurement

Recordings of the tests automatically saved to the memory

Compatibility

Designed to power various types of SMA actuators. Two power lines + two temperature sensor lines. Number one choice to power Nimesis Triggy.

Smart compact control electronics designed for easy initiation of release actuators based on Shape Memory Alloy (SMA) in test campaigns of space mechanisms. It can support various types of SMA actuators such as Nimesis Triggy or EBAD Frangibolt and allows for easy, quick and safe operation.


Built upon the experience with SMA actuators it allows to set robust safety barriers to protect the actuators and other hardware but achieve maximal performance of the actuators at the same time.
