How highly accurate programmable power supplies are used to control heater temperatures

Heaters are often used in the manufacturing of semiconductors to bond dies to wafers. For this process, the temperature has to be controlled accurately to ensure repeatability and reliability. Programmable DC power supplies are therefore used – in this, case the Z+ range. continue reading »

Why limited lifetime warranty power supplies chosen for cathodic protection systems

HWS AC-DC Power Supply

Cathodic protection techniques are used to reduce metal corrosion by making the structure the cathode and a more easily corrodible, sacrificial metal to act as the anode. For large installations like pipelines or offshore platforms, DC power supplies provide that current. The larger the structure, the more power is required. continue reading »

Dual output, rack mount power supplies save space for a wafer stepper manufacturer

HFE Front End Power supply

The word “stepper” is a shortened version of term “step-and-repeat camera”. Used in semiconductor wafer fabrication for ICs, the stepper projects an image on to a silicon wafer covered with photoresist. After this process, the wafers are washed with chemicals, cleaned, photoresist reapplied and the step repeated multiple times. continue reading »

Introducing the GQA Series of 120W Quarter-Brick Converters

TDK-Lambda presents a short video that shows the key features of the GQA series of 120W quarter-brick DC-DC converters designed for use in a wide variety of applications and environments, including industrial and comms equipment.

The units are available in four robust quarter‑brick package styles, which assist system integration in a wide variety of applications and environments. The converters have efficiencies of up to 91.5%, significantly easing system thermal management, and can operate with baseplate temperatures between -40°C and +105°C.

The GQA series is available with 5V, 12V, 15V, 24V, 28V and 48V outputs, adjustable up to ±10% to accommodate non-standard voltages. The unit operates over a 9V to 36V or 18V to 36V input range, withstanding 50V for 1 second. Input to output isolation voltage is 1,500Vdc, 2,250Vdc or 3,000Vdc depending on the package style.

Why convection cooled 200W power supplies are selected for a medical laser

Medical low power lasers use flexible fibre cables to deliver a precise beam of light for a number of applications including ophthalmology. This branch of medicine deals with the physiology, anatomy and diseases of the eye.

One manufacturer needed a convection cooled 12V output power supply rated at approximately 150W. They chose the medically certified, 200W rated CUS200M packaged in a compact 75 x 125mm (3 x 5”) footprint. TDK-Lambda was able to respond quickly with a sample and could provide short lead-times for production. To help with cable connections, the reverse connector orientation option was provided.

TDK-Lambda offers a wide range of standard and custom Medical & Scientific Power Supplies for healthcare applications – click for more information.

Dual fusing in power supplies – when is it not recommended?

By Robin Jeffery, Technical Market Analyst at TDK-Lambda EMEA

Many AC-DC electronic power supplies are now certified to meet the ITE (Information Technology Equipment) IEC 60950-1 standard and also the medical IEC 60601-1 standard. These supplies often have two internal fuses, one in the Line and one in the Neutral connection. This is to guarantee protection in a medical application where the polarity of the Line and Neutral could be interchanged due to an outlet socket or line cord wiring error.

If an electrical or electronic device consumes enough power to exceed the AC socket rating, it would need to be directly connected to the building wiring, or be permanently connected. In this case, polarity reversal is not possible. The NEC, CEC, IEE Wiring Regulations and IEC 364 though, specifically prohibit fusing the neutral in this type of equipment. continue reading »

Introducing the i3A Series of 100W, Non-isolated DC-DC Converters

The i3A series of non-isolated, DC-DC converters is ideal for creating additional mid-current output voltages from a single output 12V, 24V, 36V or 48V AC-DC power supply. These 100W step-down converters can accept a wide 9 to 53Vdc input and deliver wide adjustable output voltages of 3.3 to 16.5V at up to 8A or 5 to 30V at up to 4.5A.

The remote sense feature is available to tightly regulate the unit’s output voltage at the load during a voltage drop. Optional functions include synchronisation and sequencing, power good and positive logic on/off. continue reading »
