tvONE 1RK-4RU-PSU-2-HSWP – ONErack 4RU Hot-Swappable PSU 450W
Product Overview
The tvONE 1RK-4RU-PSU-2-HSWP is a 450W hot-swappable power supply unit designed for the ONErack 4RU chassis. It delivers centralized DC power to all modules installed in the 4RU rack frame and supports hot-swapping, allowing the PSU to be replaced without powering down connected equipment. Built-in protective features make it appropriate for mission-critical AV installations where uninterrupted power is required.
Product Description
The 1RK-4RU-PSU-2-HSWP is a chassis-specific power supply for the tvONE ONErack 4RU mounting system, providing up to 450 watts of regulated DC power to devices installed across the 4RU frame. Its hot-swap capability is the key differentiator from the standard 1RK-4RU-PSU: the PSU module can be physically removed and replaced while the chassis remains live, preventing disruption to connected AV equipment. The unit installs inside the ONErack 4RU chassis and connects via a front power connector for straightforward servicing. Two locking rear outputs provide secure, stable power connections to rack-mounted devices. Load sharing is built in, distributing the power draw evenly across connected modules. DC power conditioning, surge protection, and user-resettable fuses provide multiple layers of protection appropriate for permanent AV installations. This PSU supports dual-redundant configurations in the ONErack 4RU chassis, meaning a second PSU can be installed to provide failover protection. Available from Creation Networks, an authorized tvONE dealer.

Frequently Asked Questions
What is the difference between the 1RK-4RU-PSU and the 1RK-4RU-PSU-2-HSWP?
The standard 1RK-4RU-PSU provides 250W and requires the chassis to be powered down for replacement. The 1RK-4RU-PSU-2-HSWP provides 450W and is hot-swappable, allowing replacement with the chassis live. It also supports dual-redundant configuration.
Can I install two of these PSUs in the same 4RU chassis?
Yes. The 1RK-4RU-PSU-2-HSWP supports dual-redundant configuration, meaning two units can be installed in the same ONErack 4RU chassis to provide active failover protection.
Does this PSU fit other ONErack chassis sizes?
No. The 1RK-4RU-PSU-2-HSWP is designed specifically for the ONErack 4RU chassis. For 5RU and 6RU chassis, use the 1RK-5RU-PSU-2-HSWP or 1RK-6RU-PSU-2-HSWP respectively.
What does hot-swappable mean in practice for a live installation?
Hot-swappable means the PSU module can be physically unplugged and replaced while the ONErack chassis remains powered. Connected AV devices continue operating during the swap, with no interruption to the rack.
Is this PSU included with the ONErack 4RU Kit?
The standard ONErack 4RU Kit (1RK-4RU-KIT) ships with a 250W standard PSU. The 1RK-4RU-PSU-2-HSWP is an optional upgrade for installations requiring hot-swap or higher power capacity.
