INITIATION CONTROL UNIT

Current pulse generator for control of HDRAs

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

Key features

10 power lines

Interface for 5 actuators with redundant power lines. Up to 10A pulse per line.

Fast, synchronizable initiation

Extremely fast pulse initiation without current overshoots. User friendly control app for setup of release scenarios

Data and measurement

Time dependent data are recorded and the actuation time is calculated for QA purposes

Wide compatibility

Control from PC, compatibility with all fuse-based release actuators, separation nuts, pin pullers (NEA, Glenair, Eaton and more...)

User centered control electronics designed for easy initiation of HDRMs in ground test campaigns of space mechanisms. With intuitive control software, configuration of release scenarios becomes simple - achieved within seconds with a few clicks on PC.


The unit is able to deliver a current pulse up to 10 A (achieveable value depending on circuit resistance). Although developed for SPACERACE ATLAS, it is compatible with any fuse-based non-explosive release actuators (release actuators, separation nuts, pin-pullers..) and the completely enclosed design is cleamroom friendly.


Activation happens from an internal memory and a tripled safety barrier ensures enhanced protection during actuator initialization, effectively minimizing potential risks and ensuring security of operation.


ICU is supplied in a full set that contains:

  • Initiation Control Unit

  • PC and power cabling

  • Extension cables according to user specification

  • Thinkpad laptop

  • Rugged transportation enclosure

  • User manual
