Power Probe The PSP Power Probe is a three phase data logger, quality of supply monitor, and remote terminal unit for demand-side- management. Historical information of two months is kept in non volatile memory for later analysis. Communication options to the unit include direct connection to a computer or PDA serial port, dial- up modem, or real-time communication via the internet.

It is presently the most advanced metering chip in the world. The full functionality of this chip is exposed via a powerful main processor and communication protocol. Independent per-phase information is kept in non-volatile memory for active energy, reactive energy, voltage peaks, voltage dips and power-downs. Home
