TDK Corporation introduces the HWS3000 programmable AC-DC power supplies in the TDK-Lambda series. These units deliver up to 3000 watts in a 270 x 150 x 61mm case size. The HWS3000 offers programmable output voltages of 24V, 48V, 60V, or 130V, with the ability to adjust from zero to maximum rating. Engineers can choose between 85-265Vac single-phase or 170-265Vac three-phase input options, providing flexibility for various power environments.Programming capabilities include an RS485 interface with MODBus protocol, as well as analog 1-5V or 4-20mA signals. The power supplies feature a variable speed fan with 45dB noise at less than 70% load and 25°C ambient temperature. With an efficiency of up to 93%, the HWS3000 series minimizes heat generation, contributing to its compact design.
The HWS3000 operates in temperatures ranging from -20°C to +70°C, with start-up capability at -40°C. It provides robust isolation, with 3000Vac input to output, 2000Vac input to ground, and 1500Vac output to ground. The power supplies maintain a low leakage current of less than 0.85mA and can function at altitudes up to 5000m (2000m for IEC/EN62477-1 standard compliance).
Engineers will appreciate the scalability of the HWS3000, allowing up to 3 units in series or 10 in parallel. The series includes additional features such as a 5V 2A standby voltage, remote on/off functionality, remote sense, and fan fail and power good signals. Output terminals are configurable for horizontal or vertical connections, enhancing installation flexibility. Digital monitoring capabilities include voltage slew rate control, cumulative operating time tracking, fault logging, and product identification information.
The HWS3000 series meets a range of safety certifications and EMC standards, including IEC/EN/UL 62368-1, IEC/EN62477-1, EN55032A, EN55011-A, FCC-A, EN 61000-3-2, and IEC 61000-4. This compliance ensures the power supplies are suitable for use in various industries and applications. TDK Corporation backs these power supplies with an extended 5-year warranty, providing engineers with long-term reliability assurance.
These versatile power supplies are well-suited for applications in test and measurement, semiconductor fabrication, RF amplifiers, laser machining, printing, and various industrial equipment. The combination of high power output, compact design, and flexible programming options makes the HWS3000 series a valuable tool for engineers working on diverse power supply challenges.
