THIS IS GREAT! Now I can have computer grade power anywhere in the world!Tactical UPS® and Diplomatic Power® UPS product lines expanded

By customer request, ETI has expanded the popular Tactical UPS and Diplomatic Power global UPS product lines to include a wider range of output power and output voltages. These portable units are compact and light enough to travel with you to any destination in the world. Their global auto-ranging AC input feature means that they can use any local grid or generator power source to produce power that matches the specific voltage and frequency requirements of your computer, network and/or communications needs. Plus, these UPS eliminate all power line fluctuations, transients and distortions; providing only pure sinewave power to the critical equipment.Tactical UPS Briefcase Versions

UPS in Rugged Carry-On Case with Pop-Up Handle and WheelsIn addition, the Tactical UPS series has true global input capability by offering models with the ability to use 12, 24 or 48 VDC as an input power source (i.e. from vehicles, aircraft, etc). This gives the user the ability to use either a local AC or DC power source as input. The built-in battery module provides seamless power to your equipment if either of these sources are interrupted, allowing for the source to be restored or for an orderly shutdown. Extended battery modules are available for those applications needing longer backup times.

The output power range has been expanded to as low as 250 VA in briefcase models to as high as 3000 VA in high-impact, molded cases the size of an airline carry-on with wheels and popup handle. Each model is available with either of two output voltage ranges. The CONUS models offer an output selection of 100, 110 or 120 VAC, 50 or 60 Hz. The OCONUS models offer an output selection of 200, 220 or 240 VAC, 50 or 60 Hz. All units feature full electrical isolation from both the AC and DC inputs insuring safe operation regardless of the local country's wiring practices. GFCI protection and circuit breaker protection is available for individual outlets or all outlets. For more information, go to for first responders, military and industrial applications or for executive staff, government liaisons or diplomatic corps, where having reliable, quality power for computers and communications is important regardless of where your travels take you.

Having 3-phase input capabilty makes load balancing easier.Military Power® and Rugged Power™ UPS products now available in 3-Phase versions

ETI has introduced 3-phase capability for both the Mil Spec and rugged COTS UPS offerings. Having a 3-phase input allows the load to be spread evenly helping keep 3-phase systems in balance. These units are available with output power ratings from 3.0 to 7.5 kVA. Examples of current production units are the ETI0001-2205A3 and ETI0001-1488A1.

THIS IS GREAT! Now I can get complete shelter solutions from one source!!Tactical Shelter Systems® solutions introducedTotal Shelter Solution with Shelter powered by Solar, Wind, Fuel Cell and lastly Engine Generator

ISO Shelter energy reduction via solar power generation and reduced air conditioning requirements.ETI has teamed with Utilis USA to offer complete systems solutions for deployable shelters. Utilis manufactures a series of rapidly deployable tactical soft-wall shelters that incorporate a patented state-of-the-art folding-frame design. The basic shelters can be fully erected by two people in less than 3-minutes. By combining ETI's portable power sources, power conditioning, power distribution, office systems and shelter HVAC, either company can offer a total solution to deployable shelter requirements.

ETI also offers similar solutions for ISO shelters and other rigid-wall shelter applications. The Tactical Solar Fly™ has a double energy benefit: 1. it can generate electricity and 2. it can provide solar shading. 3rd party testing has shown the the combined benefits can reduce an installation's energy requirements by as much as 40%.

A new web site,, has been setup to provide information on the individual components as well as the various systems solutions available.

WOW! Now I can get the renewable energy in field deployable versions!Tactical Solar® lines further expanded with addition of Tactical Solar Shelters®

Tactical Solar supporting notebook in field operationETI has further expanded its very popular Tactical Solar product line, now offering the most complete line of deployable solar power equipment available anywhere. Originally developed for use by today's Warfighter overseas, it equally well suited for First Responders and other Emergency Services here in the Homeland. Developed for rapid deployment, Tactical Solar products include both fixed and flexible solar panels, solar charge controllers, battery modules and solar UPS systems. Units can be used to charge batteries in computers and communications gear and/or to operate the equipment directly. AC output voltages are also available. Most of these units are integrated into self contained briefcases and transit cases providing protection for the equipments as well as quick setup in as little as two minutes. Besides operating from solar panels, the same systems can use either DC power from military or emergency vehicles or any AC source available. The new Tactical Solar Fly offer up to 1280 watts of solar power for each 10' x 20' soft-wall shelter section or up to 1360 watts per 20 foot ISO shelter section. This solar covering also serves to further insulate the shelter reducing power required for heating/cooling of the shelter. More details can be found at Tactical Shelter Systems or Tactical Solar.

ETI's Products are Rugged from the Start, Not a Consumer Product Ruggedized.Rugged, Not Ruggedized
(Subtitled, "Not all COTS Products are Created Equal")

Most products sold in the rugged market start out as desktop or consumer products (Commercial Off The Shelf otherwise known as COTS). These vendors will attempt to "ruggedize" their product to compete in the rugged market. These ruggedized COTS products usually fail due to either temperature, mechanical shock or vibration requirements since they were not designed to withstand these extremes!

ETI's products start out rugged whether for COTS or full Mil Spec applications. They are designed to and meet Military Environmental Standards. ETI's products have successfully passed these tests numerous times including Mil STDs 167-1, 810, 901D plus surviving the vehicle mounted endurance tests in the notorious Belgium Block and the explosive charges in the Barge tests.

ETI Products have the highest level of reliability.Not the Least Expensive, But the Lowest Total Ownership Cost (TOC)

In making product evaluations today, the wise decision makers base their conclusions using Total Ownership Cost or TOC. Considering all factors, ETI products have the lowest TOC due to their overall performance and reliability. Besides the initial product cost, areas to consider are Installation, Training, Maintenance, Spares and Uptime. Products such as the ETI0001-N5 series integrate features that reduce the overall space and installation costs. Defense services and support contractors are already experienced with ETI designs and the products' operation. Manpower is a very significant factor in TOC. Very high reliability means minimal maintenance, which results in minimal manpower requirements. Once the ETI units are installed, they require very little or no preventative maintenance to keep them operational over the years. Very high reliability means a negligible spare parts requirement. If spares are desired, one set per site would be more than adequate for years of operation. Very high reliability means maximum operational uptime. Since failures usually interrupt operations at the most crucial times and since UPS or PDU reliability impacts multiple downstream loads, minimizing failures or downtime is imperative. ETI has field proven very high reliability and uptime. The Mean Time Between Failure (MTBF) exceeds 250,000 hours and the Mean Time To Repair (MTTR) is less than one half hour on most ETI products!

The US Army uses ETI's products in mobile and field deployed systems around the world, converting foreign voltages and frequencies into clean, uninterrupted US power.            The US Navy uses ETI's products on all of the ships and submarines in the US Fleet as well as in Joint Operations' mobile vehicular and field deployed systems.            The US Marine Corps uses ETI's products on radar systems, mobile vehicular and deployed systems, providing highly reliable power and frequency conversion.            The US Coast Guard uses ETI's products on their ships, aircraft and helicopters, providing clean, reliable AC and DC power.            The US Air Force uses ETI's products on aircraft as frequency converters/power conditioners allowing them to bring COTS equipment onboard at considrable cost savings.
