About us
Introduction
The BMXCPS2000 module is an alternating current power supply module.
Altitude Operating Conditions
The characteristics in the table below apply to the BMXCPS2000 power supply module for use at altitude up to 2000 m (6560 ft). When the power supply module operate above 2000 m (6560 ft), apply additional derating.
For detailed information, refer to chapter Operating and Storage Conditions.
