VNM 12 PS/PSR Power Supply • Installation Guide
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.
Features
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.
Rack Mounting
VNM 12 PS and VNM 12 PSR
With built-in brackets and supplied hardware, both
units mount in a standard 19 inch rack in a 1U space.
VNM 12 PSD
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.
PSD to PSU Connection
Refer to the diagram at right to connect the
PSU to the PSD assembly.
1. Remove the terminal cover from the rear
2. Connect the cables from the PSU D-sub
3. Plug the D-sub connector into the PSU

1. Using the supplied DC power cables, connect up to
12 VN-Matrix 200/225 or VN-Matrix 300/325 Series
encoder/decoder devices to the distribution assembly
as shown at right.
2. Connect AC power to AC connector 1/2,

VNM 12 PS/PSR Power Supply Module
Replacement
There are two LEDs on the front panel of each power
supply module. The AC Power LED indicates whether AC
power input is present on the module. The DC power LED
lights green during normal operation or red, accompanied
by an audible alarm, to indicate a failed or overloaded
supply.
If a power supply module fails, it may be replaced without removing power.

NOTE: Failed power supply modules in the VNM 12 PS can be replaced without removing AC power. However, if a
module fails, depending upon how many VN-Matrix devices are connected, DC power output may be shut
down. A failed module is identified and replaced the same as the VNM 12 PSR using the procedure below.
To replace a module:
1. On the failed module, flip the front panel security latch up to release the module, then pull it from the frame.
2. Push the replacement supply into the frame making certain it is on the mounting rails.
3. Seat the supply by pressing it into the rear connector. Both the red AC and green DC indicators light when the power
supply is properly seated.
4. Flip the security latch down to secure the module.
