Outdoor UPS system
Controlled Power Co.’s model LTN-3R UPS system features an NEMA 3R raintight enclosure. Model LTN-3R is a outdoor-rated UPS that provides output line voltage regulation of +/- 3%, magnetic isolation, filtering, and power conditioning. LTN-3R is available in 550 VA to 1.3 kVA single phase sizes. 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. LTN-3R comes with an internal status and alarm panel, with an optional clear viewing window to observe the panel’s indicators and display. Other 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.
