Compact 3 kW programmable AC-DC power supplies gain a new wide-range three-phase input variant that widens voltage compatibility and broadens deployment options across demanding industrial systems.
TDK has enhanced its high-power programmable AC-DC supply lineup by adding a three-phase input variant to its HWS3000 series, extending voltage flexibility and boosting appeal for industrial and lab applications. The latest model, designed to handle a wide three-phase input range, broadens the scenarios where compact, programmable 3 kW units can be deployed, particularly where stable multi-phase power is available or preferred.
The key features are:
- Programmable CV/CC AC-DC output up to 3 kW
- Wide three-phase AC input support (e.g., ~340 – 528 VAC)
- Digital (RS-485/Modbus) and analog control interfaces
- Series/parallel scalability for voltage/current expansion
- Compact footprint suited to bench and rack integration
Programmable AC-DC power supplies in the HWS3000 family are built in a compact 270 × 150 × 61 mm form factor, making them suitable for rack-mounted and benchtop installations where space is at a premium. These units support constant voltage/constant current (CV/CC) operation, enabling precise control of output characteristics through both digital and analog interfaces.
The new three-phase version accepts a broad range of AC input voltages (typically in the 340 – 528 VAC band), which is significantly higher than conventional single-phase designs, making it better suited to industrial environments with three-phase mains. This expanded input range gives system designers greater flexibility to fit power supplies into heterogeneous power infrastructures without the need for additional transformers or converters.
HWS3000 units are programmable via RS-485 with Modbus or analog control signals (1–5 V or 4–20 mA), allowing integration into automated test systems, production lines or research setups. They can also be connected in series for higher voltage outputs or placed in parallel for increased current capacity, providing scalability for bespoke power requirements.
Target applications span industrial test and measurement, RF systems, semiconductor fabrication and laser machining, where high-precision power conditioning is critical. With comprehensive safety and emissions certifications, these supplies are aimed at professional environments requiring both performance and compliance.
Overall, the latest addition to the HWS3000 series reinforces the trend toward flexible, high-density power solutions that address both operational and integration challenges in modern industrial and laboratory power architectures.
