IsoTek V5 Sirius – High-Current 6-Outlet Power Cleaner & Surge Protection

The IsoTek V5 Sirius is an ultra-high-performance power cleaning and distribution solution from IsoTek’s Performance Series, engineered for demanding HiFi, home theater, and network-based audio systems. With six independently filtered outlets and high-current capability, the V5 Sirius is designed to deliver clean, unrestricted power while protecting valuable audio and AV components from mains noise, surges, and voltage spikes.

For North American systems, the V5 Sirius supports up to 20A / 2,300 watts at 115V, making it especially suitable for systems that require greater current delivery. Its advanced filtering network addresses both Common Mode and Differential Mode mains noise, while IsoTek’s independent outlet architecture helps prevent connected components from contaminating one another with electrical noise.

Advanced Power Cleaning

The V5 Sirius combines a high-amperage mains-noise choke with a high-frequency Delta filter network to reduce electrical contamination across a wide frequency range. IsoTek specifies noise reduction of approximately -23 dB at 10 kHz, -40 dB at 100 kHz, and -60 dB at 1 MHz under its stated reference conditions.

This makes the Sirius particularly well suited to systems containing a combination of analog and digital electronics, where power supplies and network devices can introduce noise back into the AC line.

Independent Outlet Architecture

Each of the six outlets is individually wired back to the central power-cleaning network rather than having multiple sockets directly connected together. This design helps reduce Differential Mode noise cross-contamination between connected components.

High-Current Power Delivery

For North American installations, the V5 Sirius uses a 20A IEC C20 mains inlet and supports up to 2,300 watts at 115V. Its low-resistance architecture is designed to maintain strong current delivery, making the Sirius suitable for demanding audio systems as well as source components and network equipment.

54,000A Surge Protection

The V5 Sirius incorporates 54,000A instantaneous surge protection, designed to help safeguard connected equipment from potentially damaging mains surges and voltage spikes.

System Link

IsoTek’s System Link connection allows another compatible IsoTek power cleaner to be connected while maintaining a common star-earth reference. This makes it easier to expand a larger system without requiring additional wall outlets.
