Description

Space-Lock is developing a Power Bus Isolation Device, in the frame of an ESA development project.
Before actuation of the device, there is redundancy for reliable transmission of electrical current of up to 250 A.
Upon actuation, the device provides reliable isolation via a physical gap.
The end product will be European, and will be competitive in terms of reliability, cost and lead time.
The development project started Q1/26. TRL 6 is planned to be achieved Q2/27. Follow-on qualification is planned to be completed Q4/27.
