This control system capable of providing power & bi-directional control for 32 test sites inside a burn-in oven. The standard system is 19″ rack mountable and occupies 1RU of space. This control system is powered by a 1200W 19″ rack mount power supply which occupies another 1RU of space. There is no limit to how many systems can be used in parallel making this a modular scale-able approach to controlling a densely populated burn-in ovens. It also allows for re-racking systems to re-configure multiple ovens depending upon DUT populations per oven.
