Cyrus PSU XR External power supply

Cyrus PSU XR Power Supply

The PSU-XR is our latest external power supply and introduces a brand-new approach to providing clean and stable power for your compatible Cyrus XR host product. Incorporating its own onboard microprocessor, the PSU-XR communicates directly with the host product to consistently provide the best configuration of power from a full range of voltage output levels.

Providing multiple supplies, all of the output voltages from the PSU-XR are digitally controlled internally, so are extremely stable and virtually noise free. The PSU-XR really is our best-performing power supply, capable of providing up to 60% more power than the PSX-R2 and due to its revolutionary design, is up to 50% more efficient.

Key Features

• Power supply upgrade for XR series
• Five independent power supplies
• Full isolation for low noise
• Intelligent configuration 
• Hand built in the UK
• 3 Year warranty

There are five independent power supplies in the PSU-XR. All five power outputs route to a connected XR component through a multi-way umbilical cable

• A high-capacity logic supply to power digital circuitry in a connected XR component.
• Two fixed voltage power supplies that are intended to power sensitive, low voltage analogue circuitry.
• Two variable voltage high capacity power supplies to feed power to low or high consumption analogue circuitry. The variable power supplies also have two unregulated voltage settings that can be applied to boost the power supply in high-consumption circuitry such as power amplifiers.

Fifteen separate transformer windings, ground isolated regulation circuitry and separate output power and ground returns in the umbilical cable minimise electrical noise in the multiple power feeds to a connected XR component.

PSU-XR configuration takes place via the cable from the connected XR component. Each Cyrus design can enable and configure the power supplies in the PSU-XR to meet its circuit requirements exactly.
