Chauvin Arnoux PEL 103 Power & Energy Logger
The Chauvin Arnoux PEL 103 is an ergonomic, triple-phase power and energy logger designed to monitor electrical installations across industrial, commercial, and residential facilities. Featuring a backlit digital display, it records voltage, current, power ratings, energy consumption, power factor, and harmonics up to the 50th order—all without requiring a power outage during installation.
Equipped with a magnetic back for easy mounting inside switchboards, the PEL 103 simplifies long-term energy audits and power quality troubleshooting. Captured data is automatically stored on an internal SD card and can be transferred via USB, Ethernet, or Bluetooth. Paired with the PEL Transfer software, facility managers and electrical technicians can easily configure the device, visualize real-time measurements, and generate automated energy compliance reports.
Key Highlights
-
Comprehensive Power Measurement: Records RMS voltage, current, active/reactive/apparent power (VA, W, var), active/reactive/apparent energy (VAh, Wh, varh), PF, DPF, and tan φ.
-
Non-Intrusive Installation: Compact housing with a magnetic back panel allows secure attachment directly inside steel electrical cabinets.
-
Harmonics Analysis: Measures total harmonic distortion (THD) and individual harmonics up to the 50th order for both voltage and current.
-
Multiple Network Compatibility: Suitable for single-phase, split-phase, and 3-phase (balanced or unbalanced) electrical configurations without neutral.
-
Versatile Connectivity: Supports USB, Ethernet, and Bluetooth for remote monitoring, real-time data streaming, and seamless file retrieval.
-
PEL Transfer Software Included: Enables user-friendly setup, historical trend analysis, cost tracking, and automated reporting.
Applications & Benefits
-
Facility Energy Audits:
-
Tracks real-time and long-term energy consumption to uncover power waste and optimize energy efficiency.
-
-
Sub-Metering & Cost Allocation:
-
Allocates electrical expenses accurately across different departments, production lines, or tenant spaces.
-
-
Power Quality & Harmonics Monitoring:
-
Identifies harmonic distortion generated by non-linear loads (VFDs, UPS systems, and IT infrastructure) to prevent transformer overheating and equipment trips.
