SP 170-PDA

The only combination UPS and PDA in the marketplace

SP 170-PDA Overview

Clary’s SP 170‑PDA is another in a series of the world’s most advanced Uninterruptible Power Systems (UPS), designed to provide clean regulated power to controllers and other sensitive equipment inside the cabinet. Industry proven, the SP 170-PDA meets or exceeds Caltrans PDA requirements with on-line, double-conversion protection 100% of the time for reliable, continuous, and error-free operation regardless of utility power quality. Available in 3 models from 1250 VA / 850 W to 2000 VA / 1400 W, the SP 170-PDA has an operational temperature range of 0°C to +60°C (32°F to + 140°F), and will fit inside most existing cabinets. Options are available to accommodate intersections that have not yet replaced the yellow incandescent traffic lamps. Advanced communication features allow monitoring, configuration and control of the system over RS232, modem or network connections.
