24kW AC-DC System with 4kW Modules, Shelf, Controller, and PDU

February 20, 2019 by Scott McMahan

Bel Power Solutions, a Bel group company, announced the SPSTET4 System (Power Modules, Shelf, Controller and Power Distribution Unit (PDU). The company designed these products for systems and applications where ac-dc conversion from single-phase ac mains power to 54.5Vdc is required.

The SPSTET4 System serves as a complete computer rack power solution, and it includes the SPSTET4 (shelf), TET4000 (power module/supply), YSU.00210 (PDU) and ZLH.U1C00.0 (cable harness set), and the NAC2006-01 (controller).

Applications for the SPSTET4 system include IT racks, OCP racks, and data centers.

SPSTET4 power-shelf solutions offer rectification, system management, and power distribution. They boast high reliability and offer the flexibility for future expansion. The power shelf can be configured with up to six hot-swap capable TET4000-48-069RA ac-dc and dc-dc power supplies that convert single phase ac mains power into a main output of 54.5Vdc for powering intermediate bus architectures (IBA) in high-performance and high-reliability servers, routers, and network switches.

SPSTET4 includes a 6-slot shelf, PDU, and a shelf controller for full remote control and monitoring of the system via SNMPv1/2c/3 through a 10/100MB-base Ethernet port. The SPSTET4 can be connected directly to the data center management network.

The company designed the SPSTET4 System for secure remote monitoring. The device features full EMC and safety standard compliance and carries the CE mark. The converter can operate in a fan-cooled environment and uses digital controls for fan speed regulation. These new SPSTET4 system products are highly efficient, and the company says that they provide excellent dynamic response to load and input changes and have low output voltage noise.

Shelves are available for OCP V2 bus-bar style connection. The PDU fits into the OCP V2 4kW rack opening, and cables from the PDU to the shelf are available as well, making this a one-stop-shop V2 power solution.

The 4kW-each converters is hot-swap capable and fully protected against over-current, over-voltage, and over-temperature, and reverse polarity. Features include active analog current sharing for parallel and redundant operation, as well as secure remote monitoring with the SNMPv3 protocol via the Network Attached Controller hosted in the shelf.

Specifications

  • 3x single-phase inputs, one ac inlet power up 2 PSU modules.
  • Modules are hot-swap capable.
  • RoHS Compliant.

Features

  • Support CAN communication interface for control, programming and monitoring with CAN communication protocol.
  • Protections: Overtemperature, output overvoltage, and output overcurrent.
  • Integrates a Network Attached Controller to control and monitor the shelf via a 10/100MB Ethernet network connection

TET4000 (Power Module/Supply)

The TET4000-48-069RA (see image below) is a 4000W ac-dc power-factor-corrected (PFC) and dc-dc power supply that converts standard ac mains power or high voltage dc bus voltages into a main output of 48Vdc (42Vdc to 58Vdc) The TET4000-48-069RA meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD).

TET4000-48-069RA

Specifications

  • Best-in-class efficiency of up to 98%
  • Full power available at 200Vac to 277Vac or 192Vdc to 400Vdc
  • 4000W main output with programmable voltage set-point of 42Vdc to 58Vdc
  • Optional Standby: output 12Vdc/60W
  • Small form factor: 69mm x 40.5mm x 530mm
  • RoHS Compliant

YSU.00210 AC PDU

The YSU.00210 ac PDU converts 3-phase input to 3 x single-phase output. The main power is fed from a 3-phase delta (3W+PE) or 3-phase wye (3W+N+PE) configuration. Single-phase ac output is configured with respect to ac input configuration, delta to delta or Wye to Wye. The PDU is protected by 50A C-curve UL1077 circuit breaker. PDU offers 12 x ac appliance outlets with each protected by a 16A C-curve UL1077 circuit breaker.

Features

  • Input voltage range from 200Vac to 415Vac.
  • Can accommodate 3-phase delta or Wye configuration.
  • AC output is manually selected based on input configuration.

NACx006-01 Controller

NACx006-01 Controller

The NACx006-01 is a shelf level controller providing monitoring and control functions through a 10/100MB base Ethernet port and can be connected directly to the data center management network. It is hot-pluggable and supplied via the 12V standby delivered from the power supplies in the shelf. The controller offers a web interface for upgrading the controller, the backplane, and power supplies; the monitoring and control functions are accessed through SNMPv1/2c/3. The NAC1006-01 meets international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD).
