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
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.
1.
Remove the terminal cover from the rear
of the VNM 12 PS or VNM 12 PSR unit.
2.
Connect the cables from the PSU D-sub
connector to the corresponding power
supply terminals on the PSU.
3.
Plug the D-sub connector into the PSU
rear panel as shown.
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.
