Controlled Power Company, a U.S. manufacturer of a full line of commercial, industrial, and medical-grade electrical power solutions, announces the availability of its new  “Model LTN-3R”  Uninterruptible Power System.

Featuring an innovative, NEMA 3R raintight enclosure design, the “Model LTN-3R” UPS is a rugged, outdoor-rated UPS that provides output line voltage regulation of +/- 3%, magnetic isolation, filtering, and power conditioning … all of which contribute to the ultimate protection of the electrical load from extreme power line disturbances and power outages.

Available in 550 VA to 1.3 kVA single phase sizes, this no-break, continuous sinewave UPS provides extended battery back-up from 30 minutes to 9.5 hours, without the need for additional enclosures.   An integral constant voltage transformer isolates and regulates output voltage.   Elastomeric insulation prevents condensation and internal moisture within the UPS; and the conformal coated circuit boards are moisture-resistant as well.

The “Model LTN-3R” is provided with an internal status and alarm panel, with an optional clear viewing window to observe the panel’s indicators and display.   Other “Model LTN-3R” options include remote communications (Ethernet TCP/IP, MODBUS TCP, or MODBUS RS485), an internal heater with thermostat control, and a grade 304 or 316 stainless steel enclosure.

A free-standing outdoor UPS, the “Model LTN-3R” may be floor- or pad-mounted at its installation site.   The “Model LTN-3R” is ideal for outdoor applications such as vehicle / cargo scanning, highway tollgates / barrier control, security / surveillance systems, pumps and telemetry, irrigation systems, and transmission repeaters / cell towers.

About Controlled Power Company: As the “world’s recognized authority in power treatment”, Controlled Power Company engineers and manufactures the industry’s highest quality emergency lighting inverters and power conditioning equipment. Incorporating over 40 years of power protection technology and expertise, the company provides solid, long-lasting, integrated solutions. Please visit
