Configuration and Operation

Automatic Transfer Switch
When the Primary and Secondary inputs are both connected to Tripp Lite UPS Systems, the PDU operates as an Automatic Transfer Switch, providing redundant input power for high-availability applications. Under normal operating conditions, the PDU will distribute power from the Primary input source, switching to the Secondary input source under certain conditions. The PDU will switch to the Primary source whenever it is “Good,” according to the PDU input voltage definitions (see below).

Preferred Configuration
The Automatic Transfer Switch function provides increased availability when the Primary and Secondary inputs of the PDU are connected to separate Tripp Lite UPS Systems that are connected to separate utility power sources. For maximum availability, Tripp Lite recommends using matching SmartOnline UPS Systems with pure sine wave output for the Primary and Secondary input power sources. The automatic transfer switch function will be compromised if the primary and secondary inputs are connected to the same utility power source.TRIPP-LITE-PDUMH30AT-Automatic-Transfer-Switch-PDU-FIG-23
Warning: DO NOT connect the primary input to a line-interactive UPS, due to transfer-time issues, or to any source that does not supply a pure sine wave. Such sources may be used to power the secondary input.

Automatic Transfer Switch Source Selection
The PDU will power up if one of the input sources is greater than the minimum startup voltage. In normal operation (after power-up), if the presently selected source (primary or secondary) degrades to a lesser condition, the unit should switch to the alternate source, if that source is of better quality. The unit prefers the primary source, and will always switch to it in the event both sources are of the same (fair or good) quality. If the present source is becoming bad and the alternate source is at least fair, the unit will switch to the alternate source.

Minimum Startup Voltage 85V 163V
“Good” Voltage Range 99-139V 172-266V
“Fair” Voltage Range 75-98V 144-171V
“Bad” Voltage Range 0-74V 0-143V

Quick Test
After installing the PDU and connecting equipment, you may test the Automatic Transfer Switch function by temporarily shutting down the UPS system connected to the Primary AC input. When the Primary input UPS is no longer supplying AC power, the PDU will switch from the Primary input to the Secondary input, and the Secondary Active Input LED will be lit. When the Primary input UPS has been restarted and resumes supplying AC power, the PDU will switch back to the Primary input, and the Primary Active Input LED will be lit.TRIPP-LITE-PDUMH30AT-Automatic-Transfer-Switch-PDU-FIG-24
Note: The primary and secondary inputs must be connected to separate sources of utility power. The automatic transfer switch function will be compromised if the primary and secondary inputs are connected to the same utility power source. Do not perform a test with equipment that must remain in productive operation. Any test procedure must prepare for the contingency that the equipment may lose power. Do not test the PDU by detaching power cords connected to live power sources, as this eliminates the connection to ground and places your equipment at risk.

Remote Monitoring and Control (Select Models)
Models PDUMH30ATNET, PDUMNH30AT2, PDUMH30HVATNET, PDUMNH30HVAT2, PDUMH32HVATNET and PDUMNH32HVAT2 provide remote monitoring, outlet control and more via Web browser, telnet and SNMP-based Network Management Systems. For more information about configuration and operation of the PDU via the PowerAlert Web browser interface, refer to the WEBCARDLX Owner’s Manual included with this product or downloadable at tripplite.com.

Load “Ramping” on Startup:
All models arrive from the factory programmed so that, when first powered up, their outlets turn on in sequential order at intervals of approximately 250 ms. This prevents circuit overloads by staggering the startup of multiple devices. Models PDUMH30ATNET, PDUMH30HVATNET and PDUMH32HVATNET support user-programmable startup of outlets in any order or time interval. This ensures that network items are turned on in the proper sequence with the appropriate delay, so that network items are reliably discovered on startup.
Programmable Load “Shedding” During a Power Failure:
In the event the primary power source fails and the PDU is relying on the secondary power source, load shedding allows you to program the shutoff of specific outlets at timed intervals. This enables you to turn off less critical loads (monitors, for example) to maximize the UPS runtime for the most critical items.
