Characteristics of the BMXCPS2010 Power Supply Module

Introduction

The BMXCPS2010 module is a direct current (24 Vdc) power supply module.

Altitude Operating Conditions

The characteristics in the table below apply to the BMXCPS2010 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.
