Operating Environment
The SynQor MPC‑1250 DC Output 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 MPC will shut down if it is too hot.
The MPC (with cables connected or connector covers installed) has been qualified to the following
requirements of MIL‑STD‑810G:
