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 12 VN-Matrix 200 or 300 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:
zthe PSU (power supply unit) and,
zthe PSD (power supply distribution) panel.
The distribution assembly (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 or
VN-Matrix 300 series encoder/decoders.
Features
zCompatible with VN-Matrix 200 or VN-Matrix 300 Series encoders and
decoders.
zSimplified cabling — Two cables from power supply to distribution assembly.
zHot-swappable triple supplies (VNM 12 PSR only) — Provide redundant power for up to 12 encoder/decoder units and
enable quick replacement with zero downtime.

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.
2. Connect the cables from the PSU D-sub
connector to the corresponding power
supply terminals.
3. Plug the D-sub connector into the rear
panel as shown.
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 not labeled.
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. Go to www.extron.com for UL rack mounting
guidelines and further rack mounting details.

VNM 12 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 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 also be replaced without removing AC power. However,
if either 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.
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.
