Power Supplies
Type: Internal switching supplies on all devices
AC input: Detachable IEC cord
AC input: 90-240 VAC, 50/60 Hz
1620 Supply Output: +16 VDC @ 4.00 amps
Power Requirements
PR&E Mix Engine: <30 watts at 120 VAC / 60 Hz
EMX-16 Surface:
<15 watts at 120 VAC / 60 Hz
EMX-20 Surface: <25 watts at 120 VAC / 60 Hz
EMX-24 Surface: <35 watts at 120 VAC / 60 Hz
Razor: <15 watts at 120 VAC / 60 Hz
Environment
Ambient Temperature: Less than 40°C
Cooling: EMX Surface, PR&E Mix Engine, 1620 power supply, and the
Razor I/O Interfaces are all convection cooled (no fans). We recommend
leaving one rack space open above the power supply and Mix Engine to
allow for proper heat radiation from those units.
