PicoLog CM3 — Three-channel Current Data Logger
Compact three-channel current data logger for non-invasive current-clamp measurement of single-phase and three-phase AC loads, with USB/Ethernet connection, long-term logging and multi-unit expansion.
| Model | Channels | Input Type | Interfaces | Kit |
|---|---|---|---|---|
| CM3 | 3 channels | AC current clamps | USB / Ethernet | Kit with 3 × 200 A clamps |
Key Features
Three-channel Current Logging
Monitor three current channels for single-phase, split-phase or three-phase load analysis.
Non-invasive Current Clamps
Uses industry-standard current clamps, allowing fast installation without direct electrical connection to conductors.
USB or Ethernet Operation
Use USB for portable laptop logging or Ethernet for remote monitoring and networked data collection.
Long-term Energy Monitoring
Suitable for mains current monitoring, three-phase load balancing and energy-use recording.
Multi-unit Expansion
PicoLog can record from multiple CM3 units together, up to 60 current channels.
Clamp Kit Option
Available as the CM3 unit alone or as a kit with three 200 A AC current clamps.
