Production Test Systems Require Precise and Efficient DC Power

Manufacturers depend upon reliable, precise, and efficient supplies to power automated test equipment to help them meet production and quality goals. You can’t test and ship product if your test systems are down due to a power supply failure. Power supply failures can cause you to miss production schedules, and ultimately, adversely affect profits.

Product quality can also suffer if you choose the wrong power supplies. Automatic test equipment not only allows you to test at nominal input voltages, but at minimum and maximum input voltages as well. To run these tests, the production power supply must provide precise, repeatable test voltages. Test voltages that are not accurate may mean that you are over-testing or under-testing a product.

To test products efficiently, and keep test costs down, you need a power supply for your production test system that not only converts AC to DC, but also uses rack space and floor space efficiently. EA’s PSI, EL, ELR and PSB product series use SiC technology to efficiently produce DC power with high power density. They can supply voltages up to 2000V and output power up to 30 kW, feature auto-ranging, which can reduce instrument count in some applications, a wide variety of digital interfaces, and built-in arbitrary waveform and function generators. These features give you the flexibility to produce or sink power as needed to simulate real world conditions, with the end result being higher-quality products and lower test costs.

Powering the semiconductor industry

The semiconductor industry needs reliable, precise, and efficient power supplies to produce today’s complex integrated circuits. Reliability and repeatability are paramount for tightly controlled semiconductor manufacturing processes. EA provides the critical power supplies that meet nearly any semiconductor test need, from wafer test to burn-in.  Excellent power supplies offer precise regulation and low-noise output, allowing users to focus on their test process and not worry about configuring their power instrumentation. In this way, EA helps the semiconductor industry meet tight production schedules and produce high-quality parts, while at the same time reducing test costs.

EA Powers the Oil and Gas Industry

Harsh environments are a defining feature of the oil and gas industry, and equipment that powers this sector must be counted upon to operate reliably in this particularly harsh environment. For example, the electro-mechanical components and systems, instrumentation, industrial equipment—and power supplies—used to locate, extract, and transport hydrocarbon natural resources must be able to withstand high temperatures and pressures.
