CAUTION: 

The rear panel terminals are not color coded.  Connect the black wires to the terminal 
labeled RTN or GND.  Connect the red wires to the side that is not labeled.    

With built-in brackets and supplied hardware, both 
units mount in a standard 19 inch rack in a 1U space.  

This unit has adjustable rack ears.  It may be mounted 
directly behind the power supply if space is available. 
Alternately, it can be mounted near the PSU and as far 
to the rear of the rack as possible.  Adjust the mounting 
brackets to ensure the two main supply cables can be 
connected to the power supply.

The Extron VNM 12 PS and VNM 12 PSR power supplies provide an efficient 
method to connect power to as many as twelve (12) VN-Matrix

®

 200/225 or 

300/325 Series encoder/decoder units in 19 inch equipment racks. The single 
rack space (1U) frame houses dual power supply modules (VNM 12 PS) or 
three hot-swappable power supply modules (VNM 12 PSR).  A 12-way power 
distribution panel, VNM 12 PSD, attaches to the rear of the equipment rack. 
Cables are provided for connection between the panel and encoder/decoder 
units.
The VNM 12 PS consists of two assemblies:

 

z

the power supply unit (PSU) and,

 

z

the power supply distribution panel (PSD).

The power supply distribution panel (VNM 12 PSD) is a 1U, 19 inch rack 
mount unit that provides an interface from the power supply unit to the 
VN-Matrix 200/225 or VN-Matrix 300/325 series encoder/decoders.

Refer to the diagram at right to connect the 
PSU to the PSD assembly.

Remove the terminal cover from the rear 
of the VNM 12 PS or VNM 12 PSR unit.   

Connect the cables from the PSU D-sub 
connector to the corresponding power 
supply terminals on the PSU.

Plug the D-sub connector into the PSU 
rear panel as shown.  

 

z

Compatible with VN-Matrix 200/225 or VN-Matrix 300/325 Series encoders and decoders.

 

z

Simplified cabling — Two cables from power supply to distribution assembly.

 

z

Hot-swappable triple supplies (VNM 12 PSR only) — Provide redundant power for up to 12 encoder/decoder units and 
enable quick replacement with zero downtime.
