Lightware PSU2x20-400-12V Rack mountable power supply for Lightware interfaces - 91340022

Product Overview

The Lightware PSU2x20-400-12V is a 1U rack-mountable dual-output 12V DC power supply designed to power up to twenty Lightware interface units from a single rack unit. With a total output capacity of 400W across two independent 12V output buses, it provides centralized, reliable power for Lightware signal distribution and matrix products in commercial AV rack installations. The unit includes rack-mount hardware and is designed for 24/7 continuous operation in professional environments. Part number 91340022.

Product Description

Managing power for large deployments of Lightware interfaces becomes operationally difficult when each unit requires its own wall-wart or individual power brick. The PSU2x20-400-12V consolidates power delivery into a single rack unit with two 20-output terminal blocks, each rated to supply multiple Lightware 12V units simultaneously.

The dual-bus architecture gives installers the option to load-balance across two independent output rails, protecting against single-point power failure and simplifying future expansion. The unit is compatible with the full range of Lightware 12V-powered interface products, including TPS wallplates, extenders, and signal processing units.

For AV integrators specifying large Lightware UMX, HDMI-TPN, or HDMI-TPX deployments, the PSU2x20-400-12V is the standard rack-mounted power solution. Available from Creation Networks, an authorized Lightware reseller.

Frequently Asked Questions

How many Lightware devices can this power supply support?

The PSU2x20-400-12V provides up to 20 output connections per bus across two buses, for a theoretical maximum of 40 connected devices. The actual number depends on the power draw of each connected unit. Total output is 400W shared across both buses; verify the power requirements of each Lightware device before finalizing the load.

Is this power supply compatible with all Lightware products?

The PSU2x20-400-12V is designed for Lightware 12V DC products. Confirm the voltage requirement of each Lightware unit in your design. Some Lightware products use different supply voltages or are powered via HDBaseT (PoE/remote power) and do not connect to this PSU directly.

What input voltage does the PSU2x20-400-12V accept?

The unit accepts 100 to 240V AC at 50 or 60Hz, making it compatible with North American and international mains power. No voltage selector switch is required.

Can the two output buses be used independently for redundancy?

The dual-bus design allows load distribution across two independent 12V rails. While not a redundant power supply in the traditional N+1 sense, distributing devices across both buses means a single bus failure affects only half the connected devices.

Does the PSU2x20-400-12V require any configuration?

No. The unit is a passive power supply with no configuration requirements. Connect AC mains and terminate the output leads to the 12V power inputs of Lightware interface units.

Is rack-mount hardware included?

The unit is rack-mountable. Confirm rack ear and mounting hardware inclusion with your purchase order. Creation Networks can clarify what is included in the box.

Where can I purchase the PSU2x20-400-12V?
