How to Choose a PDU: Metered PDUs

Overview

Tripp Lite Metered ATS / Auto Transfer Switch provides a redundant power option for single-corded network devices. Dual input cords support separate connection to PRIMARY and SECONDARY power sources. The ATS will normally maintain continuous output to all outlets as derived from the primary input cable. If the primary power source becomes unstable or fails altogether, the ATS will switch over to the secondary power source until the primary input is restored and stable. Super-fast switchover between primary and secondary power sources occurs within milliseconds. ATS functionality is supported by any two compatible AC power sources, regardless of phase angle, to support a variety of advanced redundant power networking applications. Enables fault tolerant hot-swappable UPS protection when used with a single UPS and fully redundant UPS protection when each cord is connected to a separate UPS system. In a two-UPS environment, the primary input cable must be supported by a full time sine wave UPS with zero transfer time. Tripp Lite SmartOnline series is highly recommended for use as the primary UPS in a two-UPS application. ATS configurations utilizing separate mains circuits, backup generators and even separate utility power grid feeds are fully supported. On-board ATS processor constantly evaluates power quality on both input sources to prevent transfer to the secondary source when unavailable or of lower quality than the primary source. Front input LED's display primary or secondary power availability.

Features

  • 120V 20A Automatic Transfer Switch(ATS) / Metered PDU(Agency de-rated to 16A continuous)
  • Provides a redundant A/B power option for non-redundant networking equipment with a single input power cord
  • Digital display continuously reports total output power consumption in amps
  • 1U horizontal rackmount form factor; 14.5 in. / 36.8 cm depth
  • 16 built-in NEMA 5-15/20R outlets(8 front / 8 rear)
  • Set of two 12 ft. / 3.6m NEMA L5-20P input cables with set of two 5-20P adapters support connection to separate PRIMARY and SECONDARY inputs
  • ATS circuits normally maintain output sourced from the primary input cable; As primary input power fails or becomes unstable, the ATS will switch to maintain output sourced from the secondary input cable until power on the primary input is restored and stable
  • ATS configurations enable fault-tolerant, hot-swappable UPS protection when used with a single UPS and fully redundant UPS protection when each cord is connected to a separate UPS system(in a two-UPS environment, the primary input cable must be supported by an online UPS with zero transfer time similar to Tripp Lite SmartOnline series)
  • Advanced ATS configurations utilizing separate mains circuits, backup generators and even separate out of phase utility power grid feeds are fully supported
  • On-board ATS processor constantly evaluates power quality on both inputs to prevent transfer to the secondary source when unavailable or of lower quality than the primary source
  • Super-fast switchover between primary and secondary power sources occurs in 2-7 milliseconds
  • Built-in card slot supports optional SNMPWEBCARD for permanent upgrade to a switched & monitored PDU system
  • Outlets are factory programmed for sequential turn-on at 250 millisecond intervals when the PDU is first energized to prevent inrush-related equipment interaction on startup
  • Front panel LEDs confirm power availability on both input lines
  • Compliant with the Federal Trade Agreements Act(TAA) for GSA Schedule purchases

Package Includes

Comments about Tripp Lite 1.9kW Single-Phase ATS / Metered PDU 120V (16 5-15/20R) 2 L5-20P / 5-20P adapters 2 12ft Cords 1U Rack-Mount TAA:

We run an enterprise network for 250 End Users with multiple applications and systems. These devices are a nice tool for the price to help monitor the network and give some insurance in case a power source fails. I have had 4 of these online for years. No issues. The display indicates the amperage on the bus, which allows me to better balance my loads. I know exactly what is on each of my UPS systems. The fail over is fast enough from Pri to Sec to not lose a load. The Net card also allows for environmental monitoring, Input monitoring and control, as well as Load Control for cycling a load when needed. You can also shed your load so critical systems stay on the UPS longer.

I've done extensive tests on this switch in order to compare and recommend the best solution for our single cord devices in data centers.
The switching time of this product is unbelievable! Even with totally out of phase inputs.
The only thing that I do like that this switch had is preferred source selection button in front panel which gives more flexibility.

Strange Detachable Cord

By Nima

from Undisclosed

Comments about Tripp Lite 1.9kW Single-Phase ATS / Metered PDU 120V (16 5-15/20R) 2 L5-20P / 5-20P adapters 2 12ft Cords 1U Rack-Mount TAA:

Hi
I have received my order from one of our suppliers and after opening the box I found out that the second source cord is strangely detachable! As long as this product is supposed to service the critical single corded IT loads, I could not figure out the reason for making it so!
The other feature which a couldn't find was the ability to change between primary and secondary sources without rewiring and make outage to the loads!
I have found other manufactureres products more expensive but with better features!
