The PIC32CXMTSH-DB board includes the following features:
- Residential (2 voltages and 2
currents) Smart Meter Demonstrator
- Dual Arm Cortex-M4F cores and
energy metering AFE
- Voltage range measurement is from
90 Vac to 264 Vac. It can be extended to 291 Vac removing the power supply
(U1)
- Current range measurement depends
on the current sensor used and the configuration of the internal PGAs. The
current sensor input channels come populated with 3.24Ω burden resistors for a
current transformer (CT)
- Compliant with CT, Shunt or
Rogowski Coil sensors
- Opto-Port interface compliant
with ANSI C12.20 protocol for AMR
- Isolated access to metering
pulses (Wh, VARh, A2h) by an Opto-Port and/or an isolated
interface
- Flash memory for meter data
storage and firmware update
- Battery-backed real-time clock
and power supply monitor
- Custom smart meter 20-segment LCD
and control buttons
- Isolated UART interface by USB bridge
- Interface for Xplained PRO and
mikroBUSTM standard add-on boards
- Safety case to handle the board
without electrical shock risk
