PDU Installation

Demand for more computing power in less space means rack cabinets are more

densely packed than ever.

Power Distribution Units

Demand for more computing power in less space means rack cabinets are more densely packed than ever. A network PDU unit distributes power supplied to the rack via multiple outlets to the rack cabinet's servers and networking equipment.

* Choose from Power Distribution Units (PDUs) with local or remote monitoring, remote power management, auto-transfer switching for power redundancy and hot-swap capabilities

* Single-phase and 3-phase PDU options are available with vertical (0U) and horizontal (1U, 2U rack PDU) form factors

Basic PDU

TeslaWatt provides installation of Basic PDUs that distribute power to devices in the rack and they are ideal for data centers, server rooms, network wiring closets, security, audio/video and sound reinforcement applications.

A basic PDU is a dependable, space-saving, cost-effective way to deliver power to wiring closets, server rooms and equipment racks from a UPS system, generator or utility wall outlet. It complements the benefits of a UPS system by adding more outlets than are provided by a UPS to essentially convert a single high-amperage UPS outlet to multiple low-amperage PDU outlets.

A basic PDU is the easiest way to distribute facility UPS or generator power to multiple rack loads.

Metered PDU

In addition to delivering electrical power, TeslaWatt provides installation for metered rack PDUs that provide information about the power that is being consumed. It may be as simple as the voltage and the power being consumed by the PDU in total or it may provide much more power information and breakdown that information by each individual outlet. There is a wide range of PDUs that could fall under the description of a metered PDU.

Some power information that could be provided includes the following:

  • Current (A)
  • Voltage (V)
  • Actual power (kW)
  • Apparent power (kVA)
  • Kilowatt-hour (kWh)
  • Power factor
  • PDU circuit breaker current and status
  • Line current (for three-phase PDUs)

Each of these data points could be gathered for the PDU as a whole or, for more sophisticated metered PDUs, gathered for each individual outlet. On some metered PDUs thresholds can be set for some or all of the values and alerts triggered when the thresholds are crossed. A metered PDU can locally monitor load level and avoid potential overloads with a built-in digital current meter while offering reliable, rack-mount, multi-outlet, single or three-phase, power distribution from any protected UPS, generator or mains input power source.

Switched PDU

What if you want the ability to remotely monitor, connect or disconnect your data center loads? No problem! A switched PDU provides all of these capabilities. A switched PDU can locally monitor load level and avoid potential overloads with a built-in digital current meter, as well as remotely control individual outlets for the rebooting of locked equipment to avoid costly service calls, custom power-on/power-off sequences and load-shedding of non-essential loads during blackouts to extend battery backup runtime for critical equipment. Unused PDU outlets can be electronically locked off to prevent the connection of unauthorized hardware. Built-in local digital display and remote web/network interface reports detailed voltage, amperage and kilowatt output values per breaker bank / phase with additional reporting options for power unbalance percentage, IP address and optional sensor-based temperature and humidity data. The PDUs network interface connects to an Ethernet jack. Remote users can switch each of the PDUs outlets on or off via SNMP, Web or telnet.
