One of the most important requirements for excellent sound quality is the purity and stability of the AC power being delivered to the audio components themselves. Electrical energy potentially travels hundreds of miles from the generating station before reaching your home. There is certainly no high-quality power cable on this route, so the energy will encounter a whole variety of interferences on its way – from a multitude of radio signals to the feedback of thousands of electrical devices connected to the electrical grid.

Daily operation of routine equipment like computers, HVAC systems, and microwaves influence the quality of AC service. Everyone is connected to the same dirty grid polluted with excessive DC voltage, noise, and amplitude anomalies. These fluctuations in power quality have a detrimental effect on the capabilities of the connected components. They simply do not receive enough clean current to develop their full potential. The Stromtank line of models solves all these issues.

The Obvious Answer

For years, there have been many devices that use a variety of techniques to address AC power anomalies. The Stromtank models take this a step further and instead of simply adding a filter to the AC power signal, a Stromtank creates its own AC power! A Stromtank is completely independent from the traditional, fluctuating domestic power grid, by developing its own, independent power plant to supply your audio components.

Only the power generator Stromtank offers you the unique opportunity to provide your system with stable energy, completely disconnected from the electrical grid. This complete network separation works for hours and is electrically disconnected from the AC main circuits isolating your system from any AC surges, sags, noise, or radiations.

What’s inside

The heart of all the Stromtank units is the innovative battery technology known as lithium iron phosphate (LFP). Stromtank uses a special type of LFP battery that offers maximum power delivery, extended battery life, voltage stability, and intrinsic safety. The lifetime of Stromtank batteries is ensured by a battery management system that was specially developed in conjunction with the Fraunhofer Institute in Nuremberg, Germany – experts in efficient battery management technologies.

Each individual cell provides feedback to the active battery management system. This intelligent system has three major functions:

• Active balancing of all cells in the array to maximize efficiency of discharging and charging cycles.

• Inspection of temperature, voltage, current load and state-of-charge of each single cell

• By monitoring and managing the battery array, the system is completely maintenance free

Which Stromtank is right for my system?

The Stromtank family of products feature the same technology and system performance enhancements throughout the product line. The right choice for your system depends on the performance demands of your individual system components, room size, and listening preferences. Specific differences include output capability, time between battery recharging, and physical footprint.

There is an ideal Stromtank configuration for any system. The S2500 Quantum and S1000 combine Stromtank sonic enhancements with great convenience as they can be located within a typical audio equipment rack. The choice between these two units revolves around system configuration and listening habits. For more demanding amplifiers, larger, rooms, and higher listening levels, the S2500 Quantum is the correct choice. The S1000 is ideal for systems with lesser demands. Both the S2500 Quantum and the S1000 function beautifully for front end components when combined with other Stromtank models that are being employed for use with amplifiers in systems that a larger and more resolving.

The flagship S5000 HP and S4000 are perfect choices for high performance systems which include high powered amplifiers and are located in larger listening rooms. Again, the choice between these models comes down to specific system componentry, environment, and user listening style. For reference level systems that include high powered monaural amplifiers, an individual S5000HP or S4000 for each amplifier is an ideal configuration.

Coupled to an S2500 Quantum or S1000 for the front end components, you now have a completely AC isolated music or home theater system. For specific Stromtank system suggestion, please contact your dealer or Stromtank USA.

 

 

 

 

Operation

Full Battery Mode - Meter illumination is green

All audio components connected to Stromtank are supplied solely by the batteries with constant current. The average operating time in full battery mode is 4-8 hours, depending on the choice of Stromtank model and the energy consumption of the connected components. When the battery state-of-charge reaches a pre-determined minimum, the Stromtank will automatically reconnect to the AC power and recharge itself. Listening is uninterrupted and the unit will enter AC Grid mode.

AC Grid Mode – Meter illumination is blue

In AC Grid Mode, recharging occurs and listening may continue without any without disruption. When the Stromtank is connected to the AC power grid, much of the Stromtank benefits are still realized. The AC current delivered to the system is still not taken directly from the AC line but instead is absorbed by the battery. In the AC Grid mode, the Stromtank still creates a perfect AC waveform, both amplitude and frequency. This unique operation provides less interaction between the AC power line your audio video system.
