Altitude Operating Conditions
The characteristics in the table below apply to the modules BMX DDO 1602 and BMX DDO 1602H for use at altitude up to 2000 m (6560 ft). When the modules operate above 2000 m (6560 ft), apply additional derating.
For detailed information, refer to chapter Operating and Storage Conditions.
