STMicroelectronics | STPMC1BTR

The STPMC1BTR is a STPMC1 series Programmable poly-phase energy calculator IC. It functions as an energy calculator and is an ASSP designed for effective energy measurement in power line systems utilizing Rogowski, current transformer, Shunt or Hall current sensors.

This module can be coupled with a microprocessor for multi-function energy meters, or it can directly drive a stepper motor for a simple active energy meter.

Features:

• Supports 1-, 2- or 3-phase WYE and Delta services, from 2 to 4 wires
• Computes cumulative active and reactive wideband and fundamental harmonic energies
• Computes active and reactive energies, RMS and momentary voltage and current values for each phase
• Supports Rogowski coil, current transformer, Shunt or Hall current sensors
• Exclusive ripple-free energy calculation algorithm
• Programmable pulsed output
• Stepper motor outputs
• Neutral current, temperature, and magnetic field monitoring
• OTP memory for configuration and calibration
• SPI interface
• Supports IEC 62052-11 / 62053-21 / 62053-23 standards
• Less than 0.1 % error over 1:1000 dynamic range

Applications:

• Power metering
