  • Operating Temperature: -40°C to +85°C (-40°F to 185°F)

Tri-M's TPSi1085 is an isolated PC/104-Plus embedded power supply offering 2250V input/output isolation, 6000W transient protection, active input voltage clamping, wide input ranges of +9V to +33V DC, and maximum efficiency 88%. This rugged design operates in an extended temperature range from -40°C to +85°C (-40°F to +185°F), and features quick-disconnect terminal socket plugs for simple installation.

Galvanically isolated and short circuit protected, the TPSi1085 offers two standard outputs of +3.3V @ 8A and +5V @17A with total combined power of 85W. This isolated power solution also provides remote shutdown functionality, power failure signaling and three dual colour LED status indicators. For PC/104-Plus connectivity, there are also 8bit, 16bit, and PCI headers with passthrough/non-passthrough bus versions available.

For applications requiring a clean isolated power, the TPSi1085 is the perfect solution. This high density, small form factor, and unprecedented SWaP (size, weight, and performance) board is the perfect design for military, aerospace, transportation, and industrial applications.
