The Vox Power OPB is a DC Output Module designed for use within the VCCM600 series of configurable AC/DC power supplies. It provides a flexible output voltage range from 4.5V to 15V, capable of delivering up to 15A of current and a total output power of 150W.
This module features precise load and line regulation, with values of ±100mV and ±0.1%VNOM respectively, ensuring stable power delivery. It also includes over-current, over-voltage, and over-temperature protection mechanisms for enhanced reliability and safety. The module supports current sharing accuracy and has a low ripple and noise specification of 1%VNOM.
Designed for integration into modular power systems, the OPB module contributes to the overall versatility of the VCCM600 series, which is known for its fan-less architecture and conduction cooling capabilities. It supports various control features, including remote voltage and current control, and a power good signal.
Key electrical specifications include a wide input voltage range, high efficiency up to 92%, and a power factor of 0.99. The module's compact dimensions and robust design make it suitable for demanding industrial applications where reliability and performance are critical.
The output voltage range for the OPB module is manually adjustable from 4.5V to 15V.
The OPB module has a maximum output current rating of 15A and an output power rating of 150W.
Load regulation is ±100mV measured at the sense terminals, and line regulation is ±0.1%VNOM measured at the sense terminals.
The OPB module includes over-current protection (105-125%Rated), reverse current protection (-6 to 0%Rated), short circuit protection, over-voltage protection (18V), and over-temperature protection (115-125°C).
The baseplate operating temperature range is -40°C to 85°C, and the ambient operating temperature range is -40°C to 70°C (with derating above 50°C).
The efficiency of the OPB module is up to 92%.
