PXe-R Series 19-Inch Rack Mount Static Frequency Converters
PXe-110000-R Series
PXe-R Series 19-Inch Rack Mount Static Frequency Converters
PX Electronics PXe-R Series 19-Inch Rack Mount Static Frequency Converters provide compact AC voltage and frequency conversion for integration into equipment racks, laboratory systems, production test installations and specialist electrical equipment.
Available in configurations up to 5kVA, the R-Series is intended for applications that require the functionality of a conventional Static Frequency Converter in a standard 19-inch rack installation. Systems can be configured for common 50Hz and 60Hz conversion duties, with 400Hz and other specialist output frequencies available where required.
Rather than treating rack mounting simply as an enclosure option, the PXe-R Series is designed around rack integration. Cooling, mounting, electrical connections, controls and communications are considered as part of the complete installation.
The solid-state conversion stage provides controlled sine-wave AC output, with output voltage, frequency and control arrangements selected around the connected load. Local operation can be combined with remote communications and stored settings, as required.
Technical Highlights
Purpose-Built 19-Inch Rack Integration
Designed specifically for installation within standard 19-inch equipment racks, test systems and technical cabinets, with cooling, connections and operator access considered as part of the rack arrangement.
50Hz, 60Hz & 400Hz Frequency Conversion
Supports common 50Hz to 60Hz and 60Hz to 50Hz conversion duties, with selected 400Hz and specialist-frequency configurations available for laboratory, avionics and equipment-testing applications.
Compact Static Frequency Conversion up to 5kVA
Provides AC voltage and frequency conversion in a space-efficient rack-mounted format for loads up to 5kVA, subject to the required voltage, frequency and load characteristics.
Peak Current Capability for Inrush Loads
Selected configurations provide increased short-duration peak-current capability for equipment with starting or energisation current above its normal running current. Required inrush performance should be confirmed when the converter is specified.
Local Monitoring, Stored Settings & Remote Integration
Front-panel control and measurement can be combined with stored operating setups and communication interfaces to connect to computers, PLCs, and automated test systems.
Product Information
PXe-R Series System Configuration
PX Electronics PXe-R Series 19-Inch Rack Mount Static Frequency Converters are configured around the available input supply, required output voltage and frequency, load capacity and phase arrangement.
The range is available from 0.5kVA to 5kVA and can be supplied with single-phase or three-phase input and output configurations. This includes single-phase to single-phase, single-phase to three-phase, three-phase to single-phase and three-phase to three-phase conversion.
Typical applications include 50Hz to 60Hz, 60Hz to 50Hz and 50/60Hz to 400Hz frequency conversion, with output voltage selected to suit the connected equipment. This allows the R-Series to perform voltage, frequency and phase conversion within the same rack-mounted system.
All models use a compact 19-inch rack format. Chassis depth and rack height increase with power rating while retaining a nominal 430mm chassis width.
RS232 communication is fitted as standard. RS485, GPIB or Ethernet interfaces can be specified for integration with laboratory equipment, automated test systems, PLCs or remotely controlled installations.

PXe-R Series Ordering & Options
PXe-R Series model numbers identify the converter phase arrangement and power rating. The complete system is then configured around the required input voltage and frequency, output voltage and frequency, communications interface and application-specific options.
PXe-R Series Model Number
The basic model-number format is:
PXe-[PHASE CONFIGURATION][CAPACITY]-R
For example:
PXe-110003-R
This identifies a 3kVA PXe-R Series 19-inch rack mount Static Frequency Converter with single-phase input and single-phase output.
Model Number Structure
| Code | Function | Meaning |
|---|---|---|
| 110 | Phase Configuration | Single-phase input / Single-phase output |
| 130 | Phase Configuration | Single-phase input / Three-phase output |
| 310 | Phase Configuration | Three-phase input / Single-phase output |
| 330 | Phase Configuration | Three-phase input / Three-phase output |
