TD1580 DC Energy Meters Testing Device

TD1580 DC Energy Meters Testing Device

The TD1580 is a comprehensive and high-precision verification platform designed for the testing and type evaluation of static DC electrical energy meters. It integrates a DC voltage standard source, DC current standard source, DC small-signal voltage source, and a DC standard phantom power source that simulates real operating conditions using voltage-current combinations.

This system is suitable for testing both directly connected and indirectly connected DC energy meters and supports automated verification procedures required for accuracy evaluation and compliance certification. With excellent measurement stability and ultra-low ripple output, the TD1580 ensures reliable and repeatable testing performance across multiple voltage ranges.
