PS3550 - Power & Energy Analyzer

Get complete power usage and energy cost analysis in a compact, rugged package. The PowerSight PS3550 measures voltage, current, KW, KVA, KVAR, true power factor, displacement power factor, KWh, Hz, elapsed and estimated cost, duty cycle.

Long term logging for up to months at a time.

Manual waveform capture ability. Real time meter display of present values.

Bluetooth wireless and CAT IV 600V safety rating for highest safety. SD card for speed and data redundancy. The best all-around workhorse for power consumption monitoring and harmonic analysis.


It can:
  • Record energy use (kWh), and peak demand
  • Log power parameters: Volts, Amps, Watts, VA, Power Factor, etc. over time (days/weeks/months)
  • Track total harmonic distortion to the 50th harmonic
  • Display real time values on the analyzer's display – just like a multimeter
  • Display oscilloscope waveforms, harmonic spectra, phasors via a PC and Bluetooth wireless communications
  • Measure DC voltage and current
  • Monitor 50Hz, 60Hz, 400Hz, and variable frequency systems


Its rubberized contoured case and rugged construction make the PS3550 ideal for field work. Clearly labeled buttons display present values on a back-lit LCD display for quickly making spot measurements at panels and equipment. Our patented SureStart feature automatically checks for wrong connections before you begin monitoring to ensure a successful power study every time.

Use it on AC single phase or three phase circuits and loads. Data is saved to internal memory that can be downloaded to a PC via Bluetooth. Alternatively, the PS3550 includes a removable SD memory card slot (to 32GB capacity) that allows you to backup power survey data and transfer the data to a PC via an SD card. PowerSight Manager software with ReportWriter are included.


Going green? Need to control energy costs and implement energy savings measures? The PS3550 is ideal for establishing base-line data, and verifying the savings after changes have been made.


The new safety regulations demand safer tools. The PowerSight PS3550 has a 600V CAT IV safety rating (1000V CAT III) - the smart choice for working on systems to 1000V.

Be Comfortable. Be Safe. Get relief from wearing PPE.

PowerSight analyzers with Bluetooth wireless communications are the safest way to test. After installing the PowerSight analyzer and its probes, workers can get away from high voltages and Arc Flash dangers and test remotely. When at a safe distance, cumbersome PPE suits, hoods, gloves etc. can be removed. Thus workers can more comfortably control the PowerSight, view connections, phasors, and real-time values, start/stop monitoring and download data in complete safety (up to 25 feet away) via a laptop or tablet PC.
