The Legacy of HMS Power Conditioning

For decades, HMS Elektronik has developed power distribution and filtering solutions designed to reduce unwanted electrical interference and provide audio and video components with a more controlled electrical environment.

Previous generations of the Energia series introduced a range of power distributors and filters incorporating technologies such as GLS (Ground Loop Suppression), DCS (Direct Current Suppression) and carefully selected ferrite-based filtering solutions.

The products below are no longer part of the current HMS product range and are no longer in production. This archive remains available as a reference for existing owners, dealers and anyone looking for information about previous HMS Energia products.

Previous Energia Product Lineup

Energia MKII Basic

Energia MKII Basic

The Energia MKII Basic was developed as a passive power distribution and filtering solution for audio and video systems.

Its design used optimized filtering structures together with ferrite-based suppression to help reduce interference entering the system through the AC mains while maintaining unrestricted power delivery to connected components.

Offered in multiple outlet configurations, the Energia MKII Basic provided a practical entry point into the HMS approach to power distribution and interference suppression.

Energia MKII GLS/DCS

Energia MKII GLS/DCS

The Energia MKII GLS/DCS combined HMS power distribution with the company’s proprietary GLS (Ground Loop Suppression) and DCS (Direct Current Suppression) technologies.

The design was developed to address ground-loop related interference, transformer hum and unwanted distortion originating from the incoming power supply.

Together with its filtering architecture, the GLS/DCS technologies represented an important stage in the development of the HMS approach to advanced mains conditioning.

Energia RC 1/1

Energia RC 1/1

The Energia RC 1/1 was developed as a compact single-outlet power filter for use directly in front of individual audio components.

Its focused architecture combined HMS filtering principles with GLS/DCS technologies to help suppress electrical interference and transformer-related distortion before reaching the connected component.

The single-outlet configuration made the RC 1/1 particularly suitable for dedicated use with source components and other sensitive electronics.

Energia RC 3/1

Energia RC 3/1

The Energia RC 3/1 extended the RC concept to provide filtered power distribution for multiple components within an audio system.

Its internal filtering network combined GLS/DCS suppression technologies with a multi-outlet architecture intended to reduce unwanted electrical interference across a complete front-end system.

The RC 3/1 was designed for systems requiring a centralized filtering solution for several source and control components.

Energia RC 4/3

Energia RC 4/3

The Energia RC 4/3 represented an advanced implementation of the HMS Energia filtering concept for larger and more demanding audio systems.

Its architecture combined multiple filtered outputs with HMS interference suppression technologies and was designed to accommodate both source components and higher-current equipment within one power distribution system.

The RC 4/3 formed part of the previous reference-level Energia range before the introduction of the latest HMS Energy generation.

The Evolution of HMS Power Filtering

The previous Energia generations reflect the development of HMS power filtering and interference suppression technologies over many years.

Concepts including GLS, DCS and ferrite-based interference suppression established the technical foundation for HMS power conditioning and continue to influence the company’s approach today.

The current Premium Energy MC2 develops this philosophy further with Super Mono Crystal Copper internal wiring, Kapton and silicone insulation, upgraded sockets with gold-plated contacts, and a refined implementation of GLS/DCS filtering with carefully matched ferrite cores.
