About this file

This document is a Statement of Work (SOW) detailing specifications for four types of TransData units dated January 24, 2024. The SOW outlines technical requirements for current transducers (Item 1), voltage transducers (Item 2), wattage 2-element transducers (Item 3), and wattage 2.5-element transducers (Item 4).

All units share common specifications including temperature range (-20°C to 70°C), frequency range (50-70 Hz), full scale input (5 Amps), 4-20mA DC output, response time (<400 MS), surge withstand capability (5000V Peak), and utility specified steel enclosure with standardized mounting footprint. Key differences include: Items 1 and 2 are single phase with 12 electrical elements, 0-95% operating humidity, 100-130V power supply, and ±0.2% accuracy; while Items 3 and 4 are three phase with 12-14 wiring terminals, 0-99% non-condensing humidity, 120V power supply, and ±0.1% accuracy. Items 1 and 2 require zero adjustment (±5%), while Items 3 and 4 require no zero adjustment.
