IsoTek V5 Sirius Six-Outlet Power Bar

Sirius is the new twenty-amp entry to the V5 range and the answer for owners whose amplifier draws more current than a fifteen-amp bar is comfortable delivering. Six independent, star-earthed outlets with IsoTek's latest cleaning topology, now rated for a full sixteen amps at the IEC C20 inlet — twenty amps in the North American configuration — and capable of feeding a stack of amplification without becoming the current bottleneck at dynamic peaks.

The filtering steps up along with the current rating. Forty-five decibels of RFI attenuation, up from the thirty-five-decibel spec on the fifteen-amp Polaris and Corvus bars. Fifty-four thousand amperes of instantaneous surge protection. Common-mode and differential-mode noise reduction across every outlet. Multi-strand 6N oxygen-free copper internal wiring with silver plating and Teflon FEP dielectric. An easy-reset fusing system so the unit recovers gracefully from a fault. A System Link outlet supports the star-earthed growth path — pair Sirius with a Sigmas or a Titan and share the reference across the whole rack.

According to the manufacturer, the box ships with an EVO3 Premier 1.5m power cable rather than an Initium, which brings the internal metallurgy up to match Sirius's own architecture. A wall-mounting bracket kit is included, so installers can dress the bar out of sight behind the rack. In the North American configuration, up to twenty-three hundred watts of clean, star-earthed, twenty-amp power to a high-current system.
