PRODUCT

Product Information

The Quasar Rackmount Power Supply is a 2RU, rack-mountable unit that can power up to 8 modules. It offers smart protection and diagnostics capabilities similar to the Quasar Table-Top and Flush-Mount Frames. The unit includes dual redundant PSU modules and 4 independent DC outputs, each capable of supplying power to two modules when daisy-chained. The Quasar Rack-Mount PSU uses auto- sensing, auto-ranging power supplies that accept AC voltage between 90-132VAC / 187-264VAC with a frequency of 50Hz/60Hz. The PSUs are the same units supplied with the standard Quasar Console frames and are installed at the back of the unit.

Product Usage Instructions

  1. Unpack the Quasar Rackmount Power Supply unit.
  2. Connect the included External 12VDC Power Cables (p/n 17110-0506) to the appropriate DC outputs on the unit.
  3. If needed, additional External 12VDC Power Cables can be ordered from your preferred dealer.
  4. Ensure that the AC voltage supplied to the unit falls within the range of 90-132VAC / 187-264VAC with a frequency of 50Hz/60Hz.
  5. Place the Quasar Rackmount Power Supply unit in a suitable rack-mountable location.
  6. Power on the unit using the provided power switch or button.

This Quickstart Guide assumes a few things
You are setting up a Quasar Control Surface based on the ST AN DALO NE modules You did not order your Quasar Console with a full Table-Top or Flush- Mount frame.
You purchased the Quasar Direct Mount Kits, for installing the surface modules

ITEMS REQUIRED FOR INSTALLATION

The following items are necessary to complete the installation of this unit:

  • Quasar control surface modules, STANDALONE UNINSTALLED version
  • A suitable Quasar 1U or 1.SU Direct Mount Kit, for each surface module
  • lx USB 2.0 host-device cable (USB-A to USB-B connectors)
  • 2x Power (mains) cords

Unpacking the Unit
The Quasar Rackmount Power Supply, (p/n: 2001-00582-100) is a 2RU, rack- mountable unit that can power up to 8 modules. The unit offers all the smart protection and diagnostics capabilities available in the Quasar Table-Top and Flush-Mount Frames. The unit includes dual redundant PSU modules and 4 independent DC outputs, each capable of supplying power to two modules, if daisy-chained. The Quasar Rack-Mount PSU uses Auto-sensing, auto-ranging power supplies, which accept any AC voltage between 90 -132 / 187 -264VAC, with 50Hz/60Hz frequency. The PSUs are the same units supplied with the standard Quasar Console frames, and are installed at the back of the unit, as shown in the picture below:

Safety Notices

The following safety rules must be observed during installation:

To reduce the risk of electric shock, do not service personnel only. To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. This unit is not intended for outdoor use.

Mounting in a Rack

  • The Quasar Rackmount PSU is designed for high-density installations in rack furniture.
  • The unit must be rack-mounted with four screws.
  • The rack must be properly grounded.
  • No empty rack spaces are required above and below the unit.
  • The rear heat sinks must not be obstructed and a free air flow must be guaranteed.
  • Maintain a clearance of at least 10 cm behind the unit, for proper cable routing.

Warning – Make sure there is no obstruction to the rear PSU Heatsinks while it is operating, or serious damage to the unit may occur!

Redundant Power Connections
In case of service or inspection, both AC main cables must be disconnected before opening the unit.

Connections

FIG-6

  1. AC INPUT: Connect the IEC Type 73 cable supplied here. Retaining clips are provided to secure the AC cable to the sockets.

  2. FUSE: The Fuse Holder can be extracted only when the AC Mains cable is disconnected. Insert a small flat-blade screwdriver into the release notch, to open. The fuse type is 3. lA Slow-Blow.

  3. USB Control: This port can be connected to one of the MTS-MON USB ports for monitoring the voltage rails’ status and current consumption directly from the console Web UI.
    Note – Connection to this port is optional and not required for powering up and operating the unit. The max. length for passive USB2.0 cables is 5mt (15ft). If a greater distance exists between the PSU and the MTS module, we recommend using an active USB cable with PSU (not bus-powered).

  4.  12V DC OUTS: Co-connect the two 12VDC cables provided with the unit, to any one of these ports.
    Note – If you have a choice of standard and uninterrupted mains (UPS) in your studio, it is a good practice to connect each PSU to a different type of Mains supply. For example, don’t connect both supplies to the same UPS.

Earth Connection and Grounding

This is a Class I product. An Earth connection MUST be provided in each AC power cord. The Quasar Rackmount PSU is grounded through the AC power cable and therefore relies upon the proper grounding of the circuit providing AC power. In case one of the PSU inlets is connected to standard Mains and the other PSU is connected to uninterrupted (UPS) mains, make sure that both circuits are referenced to, and share, the same ground. Use the provided AC power cable(s) to connect the two PSU modules to a grounded power receptacle. We suggest connecting them to different power sources for redundancy and highly recommend the use of a UPS (uninterruptable power supply) for each source.

The Quasar Rack-Mount Power Supply does not require a separate chassis ground, therefore an Earth Lug at the rear of the unit is not provided. However, for those users who wish to have a separate ground/ earth connection using a dedicated earth cable (at least 6mm or 10 AWG cross section), this could be connected to any of the rear PSU modules fixing screw via a Grounding Tab with integrated lock washer. Such a cable is not provided with the unit, as this connection is optional and it is NOT a requirement to comply with safety standards.

Wiring DC Power to the Modules

The 12VDC Power wiring for Standalone Modules follows the following criteria:

  1. Each 12VDC Out port on the Rackmount Power Supply is connected directly to one of the 12VDC inputs at the back of a module
  2. The other 12VDC Input connector on that module is either used to daisy chain power to a second module, or it is left disconnected. The two 12VDC Input connectors at the back of each module are connected in parallel, to allow daisy chaining the power from one module to the next one, in case this is necessary. This is a useful feature when modules are installed outside of a Console frame, and no Power Distribution Board is present. Do not daisy chain more than two modules on a single DC power line.

Note – The 12VDC Input connectors are not designed to feed redundant power to each module. In case power redundancy is required by a custom installation that does not make use of a console frame, we suggest using the QuasarRackmount PSU.
Warning – Quasar surface modules can be damaged if two separate power feeds are connected to the rear 12VDC inlets.
