Chroma ATE's LED Driver Test Equipment Available from MDL

Drivers are a key element in the performance and reliability of LEDs, and an extensive range of equipment for testing LED drivers is now available from MDL Technologies. The Chroma instruments include programmable AC and DC sources, high precision power meters and an LED load simulator specifically designed for LED power drivers.

The 61500 Series advanced programmable AC power sources have output powers ranging from 500 to 2000 VA and offer AC, DC and AC+DC output modes. With a programmable voltage and frequency slew rate, they can measure RMS voltage, current, power, PF, VA, VAR, crest factor, peak and inrush current.

The Chroma 66200 Series are high precision digital power meters with a wide range of voltage, current and power parameters. User-defined criteria provide automatic pass/fail indications, and THD, inrush current and energy measurements are available.

Also offered are complete automated test systems suitable for use in R & D and quality assurance qualification as well as on the production line. One example is the Chroma 58158 AC/DC LED integrated test system which combines a programmable AC power source and digital power meter, and can integrate with a flexible optical test platform equipped with integrating sphere, photo detector etc.

MDL can also supply a 46 page guide to testing LED power drivers. Particularly useful because of the dearth of test standards for LED drivers, the guide produced by Chroma gives test specifications for a range of output parameters, such as output voltage and current, ripple current, dimming current and turn-on overshoot current. It also lists useful definitions of the relevant terminology.
