The firing units MF 28 are highly accurate current generators, programmable in amplitude and duration, specifically developed for use on pyrotechnical elements where user safety is at stake.
The MF 28 accurately control non-fire current as well as time and energy of activation. They can be used for instrumented, performance and product line tests (with process automation) on pyrotechnical elements.
Several protections are integrated into the instrument in order to guarantee a safe use in any critical environment and more particularly for pyrotechnical systems:
External safety input (door closing, barrier closing, etc.)
Safety key extractible in "SAFETY" position
Protected "MANUAL" triggering button
Safety pyrotechnical ohmmeter at measurement current of < 10 mA, allowing continuity tests to be performed (to limit and control current, even in case of failure)
DC output line to prevent build-up of electrical charges
Further key elements in MF 28 design guarantee the accurate control of the ignition:
Absence of any overshoot
Rising time < 10 ?s at 1 A
Any potential residual discharges, inopportune firing causes, are automatically removed by automatic short-circuiting of shot-firing cables.
