XP Power launches 1.3 kW power supply with 58.9 W/cm³ density

XP Power revolutionises the configurable, modular power supply market with the introduction of its FLXPro series. The FLX1K3 is a 1.3kW configurable chassis mount AC-DC power supply designed to simplify power systems for healthcare, industrial applications, semiconductor manufacturing, analytical instrumentation, automation, renewable energy systems, and robotics.

Housed in a compact 1U form factor, measuring 254.0mm x 88.9mm x 40.6mm (10.0” x 3.50” x 1.6”), the FLXPro series delivers market-leading power levels of 1.3kW at high line conditions and 1kW at low line with market-leading power density of up to 58.9W/cm³ (23.2W/in³). Its compact size and high power density reduce end application size and complexity, addressing application space constraints and the need for increased power. Designed with SiC/GaN technology and a fully digital architecture, the FLXPro achieves efficiencies up to 93% which reduces system operating costs and cooling requirements.

Flexibility and controllability are central to the FLXPro’s design. It features up to four customer-selected, inherently flexible output modules with selectable outputs from 9VDC to 66VDC and a wide adjustment range (+10% to -40%), which can be configured under live conditions to form part of a customer’s active control system. Output modules can be combined into multiple parallel and series configurations, and multiple FLXPro units can also be combined in parallel for higher power applications. This inherent flexibility optimises application performance and control, addressing customer requirements for fixed and variable loads.

A key differentiator for the FLXPro series is its uniquely designed, fully digital architecture, covering both the input stage and the output modules. This digital infrastructure is the foundation for XP Power’s new iPSU Intelligent Power technology, which translates rich internal data into usable information, enabling users to make fast, quality decisions that improve application safety and reduce operating costs.

XP Power’s iPSU technology is enhanced by XP Power’s latest intuitive user interface, XPInsight. Developed using human-centred design (HCD) principles, it simplifies system configuration, monitoring, and control, and has advanced capabilities like graphing, datalogging, and simultaneous multi-unit display. This HCD-optimised UI facilitates fast, quality decisions regarding the power supply application state and provides intuitive status, health, and configuration information. It also incorporates multi-level password protection and cybersecurity features for improved security. By streamlining power supply setup and customization, XPInsight helps accelerate development timelines and reduce engineering costs.

The FLXPro series provides extensive and unique diagnostics, including a new Black Box Snapshot feature that reduces troubleshooting time after shutdown events by recording in-depth system status at and prior to, shutdown. Additionally, tri-colour LEDs indicate power supply health with a truth table incorporated on the chassis for fast, simple interpretation without manuals or digital communications. Multiple internal temperature measurements enable fast status checks through extensive temperature diagnostics that drive intelligent fan control and over-temperature warnings and alarms.

Inputs, outputs, and firmware can be configured through the UI or directly over direct digital communications, enabling application design flexibility and tailored system integration. This allows for quick adaptation to changing application needs during design, test, and in-life operation, reducing both development timescales and system costs. FLXPro includes in-built, user-defined digital controls, signals, alarms, and output controllability, which contribute to an optimised system design and application health visibility that enables reduced maintenance/testing times and operating costs.

The FLXPro series supports ES1 isolated digital communications, which improves application safety while reducing integration complexity and supply damage risks. FLXPro uses PMBus over I²C for digital communications, enabling real-time control, monitoring, and datalogging. Standard external connectivity is provided for output modules and the system chassis, including AC OK, DC OK, remote inhibit (global/module), fan fail/temp warning, sync, and current share.

Safety and compliance are critical, with the FLXPro series conforming to medical and ITE safety approvals, including 2 x MOPP isolation for medical applications. The series is SEMI F47 compliant and meets various immunity and emissions standards, including EN61000-4 immunity and EN55011/EN55032 Class B for conducted and radiated emissions. Conformance to these regulatory requirements means a single product can cover a wide range of applications, resulting in lower design costs. It operates over a wide temperature range of -20°C to +70°C.

The FLXPro series is available from Avnet Abacus or direct from XP Power with a 3-year warranty.
