Operating Environment
The SynQor MPS‑4000 and MPPS‑4000 Series is designed for the extreme environmental conditions of
military and aerospace applications. All the electronic circuitry is contained in a sealed, weather‑proof,
shock-proof chamber constructed of die-cast aluminum. Only the redundant, water-proof cooling fans
are exposed to the environment. The Unit will shut down if it is too hot and Battle Mode is not active.
The MPS and MPPS (with cables connected or connector covers installed) has been qualified to the
following requirements of MIL‑STD‑810G:
