STPM10
Overview
The STPM10 is designed for effective measurement of active, reactive and apparent energy in a power line system using current transformer and shunt sensors. The device can be implemented for peripheral measurement in a microcontroller-based single-phase or poly-phase energy meter.
- Measures active, reactive, and apparent energies
- Current, voltage RMS and instantaneous measurement
- Frequency measurement
- Ripple-free active energy pulsed output
- Live and neutral monitoring for tamper detection
- Fast and simple one-point digital calibration over the whole current range
- Integrated linear voltage regulators for digital and analog supply
- Selectable RC or crystal oscillator
- Supports 50 - 60 Hz - IEC62052-11, IEC62053- 2x specifications
- Less than 0.1% error in the 1000:1 range
