Assemblies, as required by test plans, are tested for functionality: voltages, current limiting, overvoltage, voltage ripple, in-rush current, circuit logic functions, current sharing, protection circuitry functions, etc.
Testing and environmental stress screening (ESS) are important parts of the manufacturing process to ensure that products work for the missions they are intended. At ACT, we understand the criticality of those missions. ACT tests the performance of each of our power supplies to ensure quality and reliability. We test in order to meet or exceed application requirements defined by our customers so we can deliver a trusted power solution that will last.
When in the engineering phase, we complete early development analysis, which includes modeling and simulation. We also build prototypes for design verification or qualification testing to ensure we meet all of the customer requirements. The engineering design testing validates the design prior to release to production.
During this testing phase, products are subjected to multiple levels of testing, including temperature, vibration, shock, and other tests as specified by the design specification. EMI (Electro Magnetic Interference) testing may also be required for specific products to ensure pre-compliance of the item design. For this, we use our in-house, pre-compliance lab EMI test capabilities during engineering design and development.
Production testing goes through multiple phases depending on the unit and/or customer requirements. Preliminary tests are initial checks to ensure the unit is functioning in accordance to the acceptance test procedure (ATP) developed from the customer’s specifications. Our team will check assembly and start testing the performance of the unit. Units may also be subjected to environmental stress screening (ESS), such as vibration testing, humidity testing, and altitude testing.
Various testing is completed throughout the build process, but final testing to the product’s specific ATP is performed on every unit as part of normal production. This ensures that all units are functioning as expected to meet customer requirements. Our AC-DC MIL-COTS and DC-DC MIL-COTS are also tested to ensure no premature failures and that standard requirements are met.
Our test team is part of our quality department and risk-based thinking is part of their MO. They work closely with our engineering and manufacturing teams to reduce failures and make improvements to our designs and production process. This company-wide collaboration gives us more risk control and our customers more reassurance in our process and our products.
Our quality system at ACT is certified to AS9100D and ISO9001:2015 and valid for the design and manufacturing of rugged power supplies and electronic devices. Being a brand value, we’re dedicated to meeting quality and safety standards and delivering power solutions that work in demanding environments.
