Optima EPS has announced a new cabinet enclosure for airborne communications, mobile applications or seismic zones. Based on Optima's M-series for Seismic Zone 4 applications, the mobile cabinet features double-walled extrusions for a rugged, modular design. The first unit was built in a stacked formation with 38U on the bottom and a smaller 12U enclosure on the top. Other stacked sizes and options are available. The shelter was placed on an isolator platform for additional protection while mobile. All of Optima's M-series cabinets also feature advanced EMC shielding, reinforced corner members, cross-bracing, and stiffeners to handle rugged applications.
