The Vox Power Ltd. OPA3 is a DC Output Module designed for configurable power supply systems. It operates within a manual adjustment range of 9V to 30V, delivering a continuous output current of 15A. The module provides a nominal output power of 300W, with a peak power rating of 450W available for short durations of up to 5 seconds.
Key electrical specifications include a line regulation of ±0.1%VNOM and a load regulation of ±150mV. The module features a temperature coefficient of ±0.02%/°C and a ripple and noise level of 1%VNOM (20MHz BW, pk-pk). It also includes over-current protection set between 105-125% of rated current and over-voltage protection at 36V.
Additional features include remote on/off, remote sense capabilities, and user adjustability for voltage. The module has a bias supply of 4.5-5.2V with a maximum current draw of 10mA. It is designed for reliability, with a FIT rate of 1 at 40°C and 80% load, and comes with a 3-year warranty.
The output voltage is adjustable from 9V to 30V, with a typical setting of 24V.
The OPA3 comes in a module package.
