     Safety First - High Voltage Warning

High Voltage Warning
High voltages can scare, hurt or kill people!

Your synthesizer uses high voltages in some places!
UNPLUG AC power BEFORE opening your system!

On rack-mount systems, it's UP TO YOU to prevent access to dangerous voltages by providing a safe enclosure!

 


     Power Systems Overview

It's simple and logical, but if you need help, send me a message.

Most modules require DC power which is supplied to the circuit board behind the module's panel. Your system needs a power supply to convert the AC line voltages into DC voltages needed by the modules. A DC cable harness distributes power from the power supply to the modules. You will also need one or more power modules to control and interface to the AC line.

A typical system would use a Q101 Control Module and a Q102 AC Interface module, a power supply, and a DC cable harness. The Q137 Module combines Q101 and Q102 functions in a single panel. DC power can be distributed between cabinets using the Q103 DC Interface module and QIC cables. This allows a several cabinets to share a single power supply.

You'll find all the power distribution components on this page. Take a moment to browse and understand how the power components work together.

     QPS1 Power Supply

The QPS1 power supply provides DC power for the modules in a system.  There are two cables attached to the power supply:  One for the AC source, and one for the DC output.  The AC source cable connects directly to a Q102 or Q137 module.  The DC output cable connects to the system's DC power harness which distributes DC voltages to the modules.

Determine the amount of power needed by your system by simply adding the current for each voltage needed by each module. Since most modules draw less than 30ma on the +/-15 volt rails, and some draw none, the QPS1 will power a system of 44-66 spaces depending on the types of modules in it. Use our Spreadsheet or SynthInvent to calculate these values.

     DC Power Harnesses

The QDH20 and QDH40 DC power harnesses carry DC power from the power supply (QPS1 or QPS3) to each module in your system. The connectors are female 6 pin .1 MTA style which mate to the male connector on the circuit board of each module. They are keyed to prevent incorrect connections. One special leg of the cable has a male 4 pin Molex connector which attaches to the power supply.

Remember some modules consume more than one space, and some modules don't require power like the Q124 Multiple. The QDH20 harness has 10) 24-inch cables, and 10) 36-inch cables which is normally enough for a 22 single-width-panel system. The QDH40 harness has 20) 24-inch cables, and 20) 36-inch cables which is normally enough for a 44 single-width-panel system. The cables are long enough to allow each module to be removed from the case with access to the connector.

Using our Cable Harness with MOTM/Blacet Power Systems
The QDH cable harnesses are easily connected to MOTM-960 Power Distribution Boards by simply connecting the cable into the screw terminals. Adding Synthesizers.com modules to your MOTM/Blacet systems is easy!

Specifications
DC Power Connector to Power Supply:  4 pin .093 Molex, 24" Cable.
DC Power Connectors to Modules:  Female 6 pin .1 MTA
Maximum Current:  2 amps

Price
QDH20 (20 module cables):  $55.00 US.
QDH40 (40 module cables):  $95.00 US.

 



     Inter-Cabinet DC Power Cables

These cables connect cabinets together using Q101, Q103, Q137 Power Interface Modules via their external DC power connectors. Allows the power supply inside one cabinet to supply power to another.
