Specially designed to meet the stringent requirements of Naval and
Military Specifications (vibrations, shocks, temperature rise, etc.).
Easy to install and operate. As We manufacture a 400Hz soft starter for special applications. We are actively involved with soft starters for 400Hz and unique mil-standard requiremements for it.

Meeting Naval and Military Requirements

Thermal shocks: -2.5^oC to + 55^oC for a period of 10 cycles at the rate of 4^oC /Min

Humidity: 95% Relative conditions including vapor condensation.

Environmental: Salt fog, spray.

Acceptance Tests:

• Naval Acceptance Test Procedure
• 24 Hour testing - Every unit at 75% of Nominal current @ 47^oC ± 3^oC
• Warranty, Q.A., C.O.C. + Specification with every unit.
• E.S.S. Test - The SEM-N was subjected to std. military equipment Environment Stress Screening, followed these tests the equipment was tested to its maximum specifications.
