Eltek Valere Debuts Trilogy DC Power System for Energy Management

By Shamila Janakiraman, TMCnet Contributor

Eltek Valere (News - Alert) announced the introduction of the Trilogy DC power system, a 40-A-600A, 48V high-efficiency or HE power system which features a 15 inch shelf depth and special cable management for fitting into short-depth outside plant and central office applications.

The Trilogy DC power plant is most suitable for solar energy management as it allows service providers to utilize solar energy as a back-up power source eliminating the need for a separate discrete power plant. The Smartpack controller which is a standard feature of the Trilogy system can manage AC power input from the grid and DC solar energy input from a solar array for power conversion, explained company sources.

Eltek Valere’s market-leading Flatpack2 HE rectifier forms the basis of the Trilogy system and it features vertical cable landings for the breakers that help guide cables out of the top or side of the system besides the 15 inch rectifier depth.

In a release Allen Pitts, Eltek Valere president for the Americas region said, “Space has always been at a premium for telecom applications, but now that limitation is compounded with a desire to reduce power consumption and go green.”

“Trilogy is ideal for this next-gen network environment because it’s small and gives carriers the option of integrating alternative power sources to save money and meet their green initiatives,” Pitts added.

Company sources added that Trilogy can be configured in a two-shelf system for up to 300A of power, a three-shelf system for 400A of power or a four-shelf system for 600A of power. The shelves which can be accommodated into a 19- or 23-inch rack ensure high efficiency besides significantly reducing heat output. This in turn helps reduce cooling requirements.

Trilogy leverages 48V Flatpack2 HE Solar Chargers to convert solar energy to usable DC power for solar applications. The solar converters provide output power of 1500W with 96 percent power conversion efficiency. Also each solar charger module uses maximum power point tracking or MPPT technology for optimizing solar output and the use of solar energy collected by a solar array.

According to company sources the Smartpack controller is capable of managing both the AC mains and the input from the solar converters. The controller features built-in digital alarm inputs and form C output relays for sensors. This enables monitoring of both operational and environmental elements of the system by the controller. Smartpack also has an Ethernet port for network/Internet remote accessibility.

The other features of the Trilogy system are an AC junction box that eliminates the need to wire each power shelf. The system includes breaker-protected and bulk output landings, a low-voltage disconnect option and a two-bus system for discrete output like batteries and load within the same panel.
