To fully understand the potential benefits of Swiss Digital Fuse Box, we must first examine the pitfalls of the fuse.

A fuse is a simple, sacrificial device used to protect your component in case of electrical failure. When current is being drawn through the fuse, it begins to heat up, and in cases of excess current or short, it will melt and sever the connection to power. While this works to protect your devices, a common fuse leaves much to be desired in means of performance when it comes to our audio components. 

Regardless of the size of the power cable feeding even your largest amplifiers, the live line feeding the power supply eventually becomes constricted to the single small filament housed in the fuse. Current draw through the filament causes heat, which in turn raises the resistance and limits the capability of the power supply as it digs deep to replenish its reserves in times of high demand and musical transients. 

Our elegant solution is the Swiss Digital Fuse Box. After carefully reading the instructions, the restrictive fuse is replaced with a Sluggo, a very low resistance and high current capable metal rod made from high purity materials. Run a power cable from the wall to the Swiss Digital Fuse Box IEC C13 inlet, and then plug your component into the Fuse Box’s NEMA 15 receptacle and you are ready to experience what the Fuse Box has to offer. 

Each Fuse Box is programmed at the time of ordering to match the manufacturer’s fuse specification for your device. An internal microcontroller magnetically monitors the current draw and opens the circuit via a low resistance relay if it exceeds the pre-programmed setting. Resetting the Swiss Digital Fuse Box if tripped is done simply by disconnecting it from the wall for a minimum of 15 seconds. Fuse Box will not lose its programming ever, and will continue to protect your device faithfully and without fault. 

Please Note: We can program Swiss Digital Fuse Box for the voltage and frequency of your country, but all Fuse Boxes have a US style plug output and will require the appropriate power cable. Please see our Piggy Tail power cables if you need a short length cable for this purpose. 

Try the Swiss Digital Fuse Box for yourself in your own home. All products sold by Vera-Fi Audio are covered by a 30 day money back guarantee should you be dissatisfied in any way.

Frequently Asked Questions (FAQs)

The SDFB is a device designed to improve the performance of your audio equipment by eliminating the weakest link in every system, which is the Fuse. The Fuse degrades with time and actually imparts an Impedance in and of itself. The SDFB is MicroProcessor Controlled and uses a State-of-the-Art Hall Effect Sensor to PROTECT your equipment.

By replacing conventional fuses with a metal rod called Sluggo, the SDFB reduces resistance and allows for better current flow, leading to improved midrange and treble clarity, increased power handling, and a more defined soundstage. We can promise a more refined bottom end as well. 

The SDFB is designed to be compatible with a wide range of audio equipment. However, it's essential to verify compatibility with your specific devices before installation. Please contact us here. Fuse Box works with gear rated at 500mA to 12 amps, with either Fast or Slow Blow varieties.

The SDFB utilizes a microprocessor coupled to our precision Hall Effect Sensor / and Relay to monitor power flow, automatically opening the circuit in case of anomalies, thus providing protection without the need for a traditional fuse.

Yes, SDFB is available in three voltage configurations:

  • 110v, 60Hz
  • 220/240v, 50Hz
  • 220/240v, 60Hz (rare but used in a few parts of the world)

For users in the EU or parts of Asia, we recommend the following setup to ensure optimal performance without the need for adapters:

  1. Input Connection: Use your existing power cord to connect the wall outlet (whether Schuko or 3-blade US plug, as used in some regions) to the input side of the SDFB.
  2. Output Connection: Consider using one of our NEMA 15-type Piggy Tail power cables to connect the output of the SDFB to the IEC input of your audio equipment.

This configuration has been successfully implemented by over 200 SDFB users in the EU, delivering safe and exceptional results.

By following this setup, you can seamlessly integrate the SDFB into your system, enhancing performance while maintaining safety and compatibility.

The Piggy Tail is a short power cable designed to connect the SDFB's output to your audio equipment's power input, ensuring a secure and efficient connection.

Installation of the SDFB involves replacing the existing fuse with the provided solid copper rod and connecting the device using the appropriate power cables. It's recommended to follow the manufacturer's installation guidelines or consult a professional.
