Analyze peak inrush current with iX Series

Written on May 21, 2015 at 7:02 am, by

Many AC-powered products, such as switching power supplies and electronic lighting ballasts, draw high start-up currents to charge capacitive circuitry. Excessive inrush currents not only cause lights to flicker, but can also damage the unit. It’s important, therefore, to be able to measure inrush currents to get a handle on this problem. Traditionally, making this […]

AMETEK Programmable Power Sources Support RTCA DO-160G Tests

Since 1935, the Radio Technical Commission for Avionics (RTCA) has set the standards for commercial avionics. Chartered by the FAA to operate Federal advisory committees, the RTCA provides a forum for government/industry cooperation on the air traffic control system, as well as setting standards and guidelines needed for implementing new aircraft systems. One of the […]

Simulate high-brightness LEDs when testing drivers

Written on May 4, 2015 at 7:12 am, by

One of the challenges facing designers of lighting fixtures or luminaires that use high-brightness LEDs (HBLEDs) is testing the low-voltage, constant-current power supplies, called drivers, used to power the LEDs. Making this choice is difficult because the number of LEDS and the configuration of the LEDs will vary from design to design. To test HBLED […]
