emu3/emu3ACO Operation Guide 5
Version 2.1
General Description
General Description
The emu3/emu3ACO updates the previous IPE eMu2 PDU range.
The emu3/emu3ACO is a twelve-output power distribution unit with an embedded web server to allow IP control.
The standard model, in intelligent mode, can be set as a Master or Slave; the Automatic Changeover (ACO) model can
failover between redundant supplies.
All units contain an embedded web server, that enables continuous remote control and monitoring via the IPE
Dashboard. They can be daisychained to other emu3 units to provide up to 48 outputs via a single IP connection.
In the event of a Master unit failure, simply move the Ethernet connection to a secondary unit, which then
automatically becomes the new Master.
Units covered by this document
This document describes hardware versions v1 and v2 of the following units:
•
emu3
•
emu3ACO: 12-PMU Redundant power unit with automatic switchover (ACO)
Features
•
Sequential Switch On
: Each unit can be set up to have sequential switch on to prevent switch-on power surge.
•
Power Shedding
: Each output can be programmed to switch off when the unit is in a power saving mode.
•
Remote Control
: All outputs can be switched on or off via the IPE Dashboard web page.
•
Output Monitoring
: Front panel and web monitoring of status of output and fuse.
•
Temperature Sensor
: Rear panel connector for optional linked external temperature sensors. Critical
temperature alerts can be sent via email.
•
Current Measurement
: Overall current consumption can be monitored via the IPE Dashboard web page.
•
Auto Changeover
: In addition to all the features above the emu3ACO units have automatic changeover on
input failure, as well as a font panel switch for manual selection of input. LEDs show selected default input and
status of each input.
•
Telnet protocol
: Units can be accessed via Telnet; status & sensor values can be read, and switch outlets can be
programmed.
