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: zz the power supply unit (PSU) and,

zz 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.

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

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

zz 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.
