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.

Fuse blocks hold fuses from 50 A to 500 A

Martin Rowe — Tue, 27 Aug 2024 14:36:44 +0000

Bourns fuse blocks are available now in four styles. Two styles let you select a Class-T fuse while two others let you insert your own.

Bourns has introduced a set of four styles of fuse blocks, which mark the first fuse-block release following the company’s acquisition of Riedon in 2023.

The product types consist of the Model FB and CFB Series, which hold Class-T fuse blocks selectable from 100 A to 400 A. The fuse blocks offer two termination options including bare wire and ring/spade connections.

The other two types, the ANL fuse block Model NFB series and the NFB2 series, are available in two mounting base lengths with ring/spade connectivity with a selection of ANL fuses covering current from 50 A to 500 A.

The Model FB and CFB Class-T Series fuse blocks are made with tinned brass terminals, fiberglass reinforced polycarbonate mounting bases, clear polycarbonate safety covers, and stainless steel mounting hardware. Specifically, the compact 3.4-in. NFB Series fuse block features a base constructed of heavy duty phenolic where the Model NFB2 Series is 6.5 in. long with a fiberglass-filled polycarbonate base. Furthermore, both the Model NFB and NFB2 Series ANL fuse blocks have a clear polycarbonate safety cover and stainless-steel connection and mounting hardware that provides additional product durability and operational life.

These products are RoHS compliant.

Advanced Energy Industries, Inc. has added a fully water-cooled 60 kW option to its Ascent Arc Management System (AMS) family of DC generators for the precise control of film quality and repeatability, extending the industry-leading system with the most advanced software capabilities and the ability to operate in harsh environments.

Delivering accurate, stable, and repeatable power, the Ascent AMS II supports new materials and cathode design process innovation and enables customers to maximize productivity and reduce cost as thin film deposition areas grow. Its fully water-cooled design optimizes reliability as it keeps external debris from industrial processes out of the power supply enclosure. The expanded operating range of Ascent AMS II increases process capability. It also fulfills global most input requirements with a single part number – simplifying tool installation.

Embedded PowerInsight by Advanced Energy software provides actionable intelligence that can be applied to optimize processes for improved throughput and yield, as well as reduce unplanned equipment downtime.

Ascent AMS II is ideal for physical vapor deposition (PVD) processes for thin films on flat panel displays, glass, solar and other industrial coating applications. This platform can be used directly in DC processes or combined with Advanced Energy’s Ascent DMS (dual-magnetron sputtering) for bipolar DC processes.

The 60 kW Ascent AMS II power supply is on display at AE’s booth (#1003) at the 67^th annual Society of Vacuum Coaters (SVC) Technical Conference in Chicago taking place this week.
