PS4550 – Power Quality Analyzer
$5,265.00
The PS4550 is a true hand-held three-phase power quality analyzer with the features and accessories to achieve success in your power monitoring study. Its ergonomic contoured case, rugged construction, and small size make it ideal for field work. In addition, being part of the PowerSight “Start-To-Finish Monitoring Solution”, it has unique features and accessories that you will not find elsewhere to:
- Save time
- Eliminate errors
- Achieve success.
Power Quality Analysis
Continuously examine every cycle of every input and trigger to a resolution of 8 microseconds. Trigger on swell, sag (dip), inrush, and advanced triggering types such as absolute and relative high-speed transient events. Choose your triggering mode:
- Allow the trigger thresholds to be set automatically for you by the meter, based on the voltages it sees
- Set the trigger thresholds yourself for voltages and currents, setting swell, sag (dip), inrush, absolute transient levels, and relative transient levels.
Power Logging
Monitor just about any power system or load in the world:
- 3-phase delta/wye, 4-wire delta, open/grounded delta, 2CT/2PT – 3CT/2PT – 3CT/3PT metering circuits, split-phase, single phase, multiple single phase, and of course DC.
- Select any of 72 different measurement types for regular recording of Voltage (V), Current (A), Power (KW), Apparent Power (KVA), True Power Factor (PF), Frequency (Hz), and THD.
- Many other measurements available on the screen (such as elapsed & projected cost and KWH, peak demand period, duty cycle, “on” time, DPF, phase angle, individual harmonics…)
- Reports can also include peak demand period and magnitude (both KWH and KVA), estimated and elapsed cost, & average KVAR with graphs and starting waveforms.
- Summaries of the average, maximum, and minimum of each value, as well as the present values can be viewed on the analyzer’s display at any time.
- All measurements and the initial automatic capture of waveforms can be viewed and analyzed in our Windows PSM-A software (power analysis features).


Harmonic Analysis
Log the THD of each input. Capture waveforms in the PS4550 with the press of a button at any time and then analyze the harmonic content with our Windows PSM-A software (power analysis features) as either a harmonic bar chart or as an exported Excel spreadsheet.

Typical PS4550 Applications
Evaluate Quality of Incoming Power
Verify that your utility is delivering power within an acceptable voltage range over time. Check if nearby facilities are affecting your power. Verify if long power lines or over-capacity situations are having an adverse effect on your operations. Trigger on voltage swells and sags. Trigger of high speed transients. See what is happening in several different presentation viewpoints. PowerSight is unique in its ability to connect directly to distribution power (with optional medium voltage probes) to see what is happening at the source.
Evaluate Quality of Power Within Facilities to Find Failure Causes
If equipment is failing prematurely or is mysteriously taking itself off-line, you want to evaluate the voltage of the branch line and the current draw of parallel circuits. In addition to fine logging, trigger on swells and sags of voltage and inrush of current. Capture several views of what is happening in order to evaluate the source and the solution of the problem.


High Frequency Studies
When the Frequency Analysis Option (FAO) is enabled, the PS4550 effectively becomes a spectrum analyzer, capable of measuring high-frequency power line noise up to 100,000Hz. Common applications include where high-frequency noise could affect sensitive electronics, interfere with specialized manufacturing processes, cause high frequency currents, or disrupt communication signals.
Evaluate Harmonic Distortion of Power
Modern electronic equipment introduces harmonics into a power system, which can have unforeseen consequences. Safety risks related to overheating can arise but can easily be identified by an analyzer with harmonics analysis.
Verify ATS & Backup Power
Trigger on loss of power to record the response of your ATS and backup power systems. Just as importantly, judge the handover of power from battery to diesel and from diesel to utility upon recovery. Trigger on current spikes and voltage over/under voltages that can damage equipment.


Long, Extended Studies
Every PS4550 comes standard with expanded internal memory storage. What’s more, every PS4550 system includes an SD memory card that, when inserted in the analyzer, provides virtually unlimited data capacity. Verify currents for ampacity before adding new loads. Determine the load profile of any equipment, branch, or facility for power management and load shedding. Appropriately size breakers, transformers, power factor correction, and power backup.
Cost & Efficiency Analysis
Automatically view projected cost, run time costs, peak demand period, power factor profiles and more to verify projected savings, check utility bills, shed loads, minimize power factor penalties. Perform before/after and A/B analyses for informed decision making. Our ReportWriter Wizard™ provides clear summaries and comparisons with a minimum of effort.

Recommended Add-Ons
eFX6000 – Flexible current probe: 1-6000 amps
Wide Range Flexible Current Probe 1 – 6000 Amps
The eFX6000 is a flexible AC current probe covering the entire measurement range of 1 to 6000 amps. The rope is just 0.91 inches (23 mm) thick so it can fit through narrow places and is 24 inches long so it can wrap around multiple cables or a busbar (36 inch length is also available). Self-powered via our meter, so there are NO batteries that can run down.
$395.00
LDCm – 480V Line-to-DC Converter
A favorite of professionals. The LDCm will power your analyzer off of the voltage that it is monitoring in the range of 100-480V. This allows locking your analyzer inside of a power panel with no power cord entering the closed panel. This provides maximum safety and security. Added safety is achieved by eliminating the use of extension cords. The small size and short voltage leads allow fitting the LDC into any space near your power analyzer in cramped electrical panels.
$345.00
MEM2 – Extended Memory Upgrade for PS4550/PS3550
Only for PS4550/PS3550/PS4500
The Expanded Memory Option is recommended for the PS4550 to provide plenty of space for extensive data logging and power quality data capture. It expands the internal memory four times (X4). Standard memory is adequate for limited power logging and power quality data capture.
$245.00
5KVPSet – 5kV High Voltage Probe Set
5 KVP Voltage Probes (3 Probes, Case)
The PowerSight 5KVPSet allows you to safely directly monitor medium voltages up to 5KV. It is a set of three probes. Great for use with 4160V motors. Your only choice when there are no PTs (Potential Transformers) available or you want to bypass PTs.
