Model LTN-3R UPS
Purpose-built for rugged outdoor applications where uninterrupted, conditioned power is critical.
The Model LTN-3R UPS (550VA – 1.3kVA) is purpose-built for rugged outdoor applications where uninterrupted, conditioned power is critical. Unlike typical outdoor UPS units that offer only standby backup with minimal voltage regulation, the LTN-3R integrates a constant voltage transformer to deliver ±3% regulated, continuous sine wave output with magnetic isolation and full power conditioning. Its NEMA 3R rain-tight enclosure withstands harsh environments from -35°C to +55°C, while internal battery options provide runtimes from 30 minutes to 9.5 hours. Ideal for security, traffic control, telecom, and industrial sites, the LTN-3R ensures reliable performance in the most demanding outdoor environments.
