True RMS 3-Phase Monitor
The MODEL 25 True RMS 3-Phase Monitor, SKU 25SG, delivers critical protection and operational oversight for industrial electrical systems. Its broad input voltage capability, spanning 80-550 VAC, ensures compatibility across various power configurations. The monitor provides a robust 10A @ 240V AC resistive output, facilitating reliable control of connected equipment. Precision is a core attribute, evidenced by a repeat accuracy of ± 0.5% under consistent operating conditions. Engineered for longevity, the device boasts an electrical relay life of 100,000 minimum operations at its rated load. Environmental resilience is key, with effective operation from -20°F to +130°F and tolerance for 0-97% humidity without condensation. Installation is streamlined via DIN Rail 35mm mounting. This monitor contributes to enhanced system integrity and reduced downtime through its consistent performance and protective features.
