Every measurement, every event, on every cycle, all the time – without thresholds
From set-up to finished reports, the RPM Power Recorder is the complete solution to your portable power monitoring needs. The Power Recorder analyzer is all you need to monitor, study and document:
- Loading and load interaction
- Power consumption and demand
- Sags, swells or transient events
- Ground currents
- Phase relationships, including phase imbalance
- Frequency stability
- Harmonics and noise
|
The Power Recorder features:
- 4 voltage channels – three phases plus neutral-to-ground. Measures up to 600 Vrms, 1000 Vpeak.
- 5 current channels allow you to monitor neutral and ground current, in addition to phases
- Extruded metal enclosure, and designed to handle a life-time of use
- Ethernet interface makes downloads fast and easy
- Capture up to 6,000 simultaneous voltage events with simultaneous current in each monitoring session
- Multi-session option allows for 16 sessions, effectively multiplying event capture capability to 96,000 events
- 128 samples per cycle — on every cycle
- Supports single-phase, wye, delta, split phase, high-leg delta, open-leg delta, and other common power systems
- Power Consumption option adds Watts, VA, VAR, PF trends and measurements
- Harmonics option measures harmonics up to 63rd
- Optional 2 MS/s sampling system for capturing and viewing high-speed transients
- Nylon and hard-sided cases, mounting brackets, a wide variety of voltage and
current probes are available
