TD140 System Operating Specifications
Rev. 001-140228
The AC power supply shelf supports up to four AC rectifier modules. The power output per
rectifier is dependent on the AC input voltage. For the TD140 80G configuration, two AC
rectifier modules are included. This provides redundant power. Load sharing between the
modules is not ideal because the power paths are independent. This provides notification
when a power rectifier fails.
lists the power and heat specifications for the TD140 with an AC Rectifier.
Typical and maximum power draw will be distributed across the AC power feeds, but it will
not be balanced. It is not unusual for a single AC rectifier to supply 80% of the power.
