What is a vacuum capacitor?

Our storage device, the Vacuum Capacitor, is similar to a supercapacitor, but energy storage is achieved by using new physical principles. Thanks to the patented structural features, our Vacuum Capacitor is able to store charges (electrons) inside a small vacuum chamber, under high electrical field.

What is a vacuum contactor?

Vacuum contactors are key components in any switched capacitor bank. They are the preferred switching device for various medium-voltage (MV) assets such as motors, transformers or reactors. Furthermore, they are an integral part of most MV motor control centers (MCC) or soft starter designs.

What are energy storage capacitors?

Ceramics are ubiquitous and widely Energy storage capacitors can typically be found in remote or battery powered applications. Capacitors can be used to deliver peak power, reducing depth of discharge on batteries, or provide hold-up energy for memory read/write during an unexpected shut-of.

How much energy can a vacuum cap store?

One such prototype Vacuum Capacitor (“VC”), approx. 50 g and 7 cm height, will typically be able to store approximately 1 kWh of energy (charges stored inside the top white ceramic cap, under vacuum).

What are energy storage capacitor specifications?

Capacitor specifications of capacitance, DC leakage current (DCL), equivalent series resistance (ESR), size, etc. are typically room temperature measurements under a very specific test condition. Furthermore, energy storage capacitors will often be set up in some parallel/series combination that can pose unique challenges or unexpected behaviour.

What is an Epcos vacuum contactor?

They are the preferred switching device for various medium-voltage (MV) assets such as motors, transformers or reactors. Furthermore, they are an integral part of most MV motor control centers (MCC) or soft starter designs. EPCOS vacuum contactors are designed and tested in compliance with the relevant international standards.
