PS4500 – Power Quality Analyzer

We recommend the PS4550 over the PS4500 for new purchases.

This was our best Power Quality Analyzer prior to being replaced by the PS4550. Excellent power monitoring and analysis coupled with sophisticated triggering and event capture. Eliminate errors and increase your productivity from start to finish with SureStart™ connections expert, Data Setup wizard™, and ReportWriter wizard™.

We recommend the new PS4550 over the PS4500 for new purchases.

It can:

• Catch power quality events such as fast transients (impulses) to 8 microseconds, voltage sags (dips), and swells.

• Measure total and individual harmonic distortion to the 50th harmonic

• Record energy use (kWh), and log all power parameters: watts, VA, Power Factor, etc.

• Data log RMS voltage and current over time (days/weeks/months) with down to one second resolution

• Display real time values in meter window – 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

HANDS-ON CHOICE!

It’s rubberized contoured case and rugged construction make the PS4500 Power Quality Analyzer ideal for field work. Clearly labeled buttons display present maximum, minimum, and average values on a back-lit LCD screen for quickly making spot measurements and over-all evaluation 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 just about any type of power system in the world. Redundant communications and data storage so there is always a way to communicate and get data. Set logging period from 1 second to 99 minutes for months of logging. At 1 second logging, capacity is limited by the size of your SD card (32GB maximum). Data is saved to internal memory that can be downloaded to a PC via Bluetooth. Alternatively, the PS4500 includes a removable SD memory card slot that allows you to backup power survey data and transfer the data to a PC via an SD card. PC software and Report Writer are included.

EVERY CYCLE EXAMINED – FAST!

High-speed Power Quality Analyzer sampling to 8 microseconds offers high performance for capturing spikes and transients. Cycle-by-cycle RMS measurement provides the greatest accuracy for data logging. Half-cycle RMS measurement provides highest resolution for triggering and tracking voltage fluctuations. Continuous sampling ensures no cycle is missed on any input. The meter is never “blind” or idling.

SAFE FOR NFPA 70E AND CSA Z462 COMPLIANCE

The new safety regulations demand safer tools. The PowerSight PS4500 has a 600V CAT IV safety rating – the smart choice for working on systems to 600V.

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

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