Power Supplies
PX Electronics supplies Power Supplies for electrical testing, product validation, critical-load support and specialist AC power applications.
The PX range includes variable AC power supplies, programmable AC power sources and dual redundant AC power supplies. Each product type is intended for a different requirement. Some applications need adjustable voltage and frequency for test work. Others need programmable supply conditions, repeatable test routines or a reliable AC output for communications, control and monitoring systems.
PX Electronics helps customers select the correct power supply around the available input supply, required output, connected load, control method and installation environment.
Available Power Supply Products
PX Electronics offers a focused range of Power Supplies for laboratories, manufacturers, infrastructure sites and engineering teams.
Choosing the Correct Power Supply
Different power supply types solve different problems. The correct selection depends on whether the priority is controlled AC output, programmable testing or continuity of supply.
| Power Supply Type | Best Suited To | Typical Requirement | Product Range |
|---|---|---|---|
| Variable AC Power Supply | Product testing, validation, production checks and laboratory power | Adjustable AC voltage and frequency | PXe-A Series |
| Programmable AC Power Source | R&D testing, compliance support, automated test systems and supply simulation | Programmable voltage, frequency, ramp and transient functions | PXe-AFV-P |
| Dual Redundant AC Power Supply | Telecoms, SCADA, utilities, control rooms and remote infrastructure | Continuous AC output with DC input and AC bypass | PXe-BLS |
Core Power Supply Capabilities
Controlled AC Output
PX power supplies can provide controlled AC output for equipment testing, production checks, electrical validation and specialist load operation.
Adjustable Voltage and Frequency
Variable AC power supply configurations allow engineers to test equipment under defined voltage and frequency conditions rather than relying on fixed site mains power.
Programmable Test Functions
Programmable AC power sources are available where the application requires repeatable voltage changes, frequency variation, ramp functions, transient generation or automated test integration.
Critical AC Load Support
Dual redundant AC power supplies are available for systems where AC output continuity is important, particularly in communications, control and monitoring environments.
Single-Phase and Three-Phase Options
Selected power supply ranges can be configured for single-phase and three-phase applications, depending on the product type and output requirement.
Monitoring and Communication
Systems can include front-panel metering, alarm indication, remote interfaces, dry contacts and communication options depending on the selected product.
Typical Applications
PX Power Supplies are used where engineers need controlled, stable or resilient AC power for equipment and systems. Typical applications include:
- Product development and validation
- Electrical equipment testing
- Laboratory and R&D power systems
- Production line functional testing
- 50Hz and 60Hz product evaluation
- Export product testing
- Over-voltage and under-voltage checks
- Programmable AC supply simulation
- Aerospace equipment testing
- Appliance and electronics testing
- Industrial control equipment
- Telecoms and communications infrastructure
- SCADA and monitoring systems
- Railway and transport networks
- Control rooms and remote sites
- Critical AC load support
Power Supply Selection Guidance
A Power Supply should be selected around the electrical requirement and the behaviour of the connected load. For test applications, the main considerations are output voltage range, frequency range, accuracy, waveform quality, load current, peak current, control method and whether programmable routines are required. PX Electronics will normally review:
- Available input supply
- Required output voltage
- Required output frequency
- Single-phase or three-phase requirement
- Continuous power or current
- Load type
- Starting or inrush current
- Duty cycle
- Required control method
- Monitoring and alarm requirements
- Installation format
- Environmental conditions
- Test documentation or compliance requirements
For infrastructure applications, continuity of supply, transfer time, alarm outputs, remote monitoring, DC input voltage, AC bypass arrangement and rack-mount installation may be more important than wide output programmability.
Why Choose PX Electronics for Power Supplies?
PX Electronics supplies configured power supply systems for technical and industrial applications where a standard plug-in supply is not suitable.
A laboratory AC test supply, a programmable AC source and a redundant infrastructure power supply are not specified in the same way. Each has different priorities, from voltage and frequency control through to automated testing, alarm signalling and continuity of supply.
PX supports customers through specification, quotation, supply, factory testing and after-sales support. Systems can be configured with suitable output ratings, enclosure formats, communication interfaces, connectors, documentation and application-specific options.
Power Supply FAQs
What is a power supply?
A power supply provides electrical power to equipment at the voltage, current and output format required by the load.
In the PX range, Power Supplies are used for AC testing, controlled voltage and frequency output, programmable test power and critical AC load support.
What is an AC power supply?
An AC power supply provides alternating current output. It may be used to operate equipment, test electrical products or provide a controlled AC source where standard mains power is unsuitable.
What is a variable AC power supply?
A variable AC power supply allows the output voltage, frequency or both to be adjusted. This is useful for product testing, validation, laboratory work and checking equipment behaviour under different supply conditions.
What is the difference between an AC power supply and a programmable AC power source?
An AC power supply normally provides a controlled fixed or adjustable output.
A programmable AC power source provides more advanced test functions, such as programmable voltage and frequency changes, ramp functions, transient generation and automated test routines.
What is a dual redundant AC power supply?
A dual redundant AC power supply maintains AC output by using more than one available power source. The PXe-BLS system can operate from a DC input and transfer to AC bypass when required, helping support critical connected loads.
Which PX power supply is right for testing products?
For general voltage and frequency testing, the PXe-A Series variable AC power supply is usually the starting point.
Where the test requires programmable changes, transients, ramp functions or automation, the PXe-AFV-P programmable AC power source may be more suitable.
Which PX power supply is right for critical infrastructure?
The PXe-BLS dual redundant AC power supply is intended for applications where continuity of AC output is important, such as telecoms, SCADA, utilities, transport networks and remote control systems.
Can PX power supplies be integrated into automated test systems?
Yes, selected models can be supplied with communication interfaces for remote control, monitoring or test-system integration. The required commands, protocol and readback values should be confirmed before specification.
Can PX power supplies support non-linear or high-inrush loads?
Yes, provided the supply is correctly selected. Loads such as motors, transformers, rectifier inputs and capacitive power supplies should be assessed using peak current, inrush duration, power factor and duty cycle, not only continuous running power.
What information is needed for a quotation?
PX Electronics will need the available input supply, required output voltage and frequency, load rating, load type, starting current, control requirement, installation environment and any documentation or test requirements.
