VCCS300S puts power into smaller spaces
The conduction-cooled power supply delivers power densities in excess of 23W/in3. It provides silent and dust-free output power for the industrial sector, for system integration, in particular in robotics, automation, test and measurement and industrial lasers.

The 310g power supply delivers up to 80% more power than competitive products in the same package, claims the company. Depending on the application and working environment, the power supply can also be convection or forced-air cooled.

The power supply achieves up to 95% efficiency and - when mounted correctly – its cooling techniques allow for very effective heat dissipation for full power operation up to 40°C ambient.

The power supply complies with UL/IEC62368-1 and various MIL-STD standards for use in ruggedised environments.

By bringing units together, either in parallel or in series, output power can be scaled to 600W, 900W and above.

“What we have done with the VCCS300S is successfully converge two power market segments” says Marco Prinsloo, CEO, at Vox Power. “On the one hand, there are miniaturised applications which may have limited space for a power supply but have increased power requirements to achieve the required application feature set. . . Then, there are higher power applications where customers want to reduce the size of their offerings but are again limited because higher power units are only available in larger footprints.”

Input voltage range is 85 to 264V AC (0.99 power factor) and output voltages are set initially at 12, 24 and 48V DC with in-between voltages up to 58V DC available on request. Figures for load and line regulation as well as ripple and noise are excellent, reports Vox Power, while no-load power consumption is below 1W.

The power supply also has low leakage and touch current levels and protection against over voltage and over temperature, both with auto restart. Over current and short circuit protection are also standard.

The new power supply is widely available from a global distribution network and is backed by a five-year warranty.
