78M6610+PSU - Maxim

78M6610+PSU Energy Measurement Processor

The 78M6610+PSU is a single-core energy measurement processor for single-phase power supplies. It is designed specifically for real-time monitoring at the input of AC/DC power converters used in data centers and IT server rooms. It is available in either a 24-pin QFN or 16-pin TSSOP package for optimal space savings. The 78M6610+PSU provides four analog inpu.

Features

• Delta-sigma ADC with precision voltage reference
• Internal or external oscillator timing reference
• SPI, I2C, or UART interface options with configurable I/O pins for alarm signaling, address pins, or user control
• 24-bit energy measurement processor (EMP) with integrated firmware and flash memory provides the user with: o True RMS calculations for current, voltage, line frequency, real power, reactive power, apparent power, and power factor o Compensation for ambient temperature, sensor tolerances, offsets, and EMI filter components o Real-time data accumulation based on an integer numbe.
