Dual slot 300W power modules have medical approvals
Two 300W power modules extend the range of medical applications for Vox NEVO+600 and NEVO+1200 modular power supplies.

Vox Power has launched two 300W output power modules that extend the range of medical applications for its NEVO+600 and NEVO+1200 modular power supplies.

The 300W dual slot OPA2 and OPA3 power modules provide manually adjustable output voltages of 4.5 to 15V at 25A and 9 to 30V at 15A respectively for the NEVO+ power supplies.

The NEVO+600 units used up to four isolated, configurable power modules to achieve up to 600W while the larger 1200W model used up to eight modules. The OPA2 and OPA3 output modules reduce that to two and four respectively, allowing developers to minimise cable and link requirements and part count. This in turn means simplified construction, increased reliability and, for most applications, a reduction in overall system costs.

The larger 1200W unit measures 152.4 x 152.4 x 40.8mm (6 x 6 x 1.61in) resulting in a power density of 21W/in³. Importantly for some applications, the NEVO+1200 weighs 1.2kg and has 90 percent efficiency as well as a standby power of less than 3W, accurate current sharing and the ability to connect modules in parallel and series. As well as remote current and voltage programming, NEVO+ units can be configured in the field. There is also a low-noise fan option.

Medical approvals for NEVO+ power supplies include EN/IEC/ANSI 60601-1 for safety and EMC EN60601-1-2 4th edition for EMC immunity. Applications include diagnostic systems, medical robotics, dialysis / peristaltic pumps, laboratory and analysis equipment, incubators and many others where high-power levels are needed in a small space.

Like the NEVO+ units, the modules are approved to EN/IEC/ANSI 60601-1 and EMC EN60601-1-2 4th edition. These high reliability output modules (1 FPMH at 40⁰C at 80% load) include protection against over- current, voltage, temperature and short circuits and Vox Power has included a 5V, 10mA bias supply.

Like all Vox Power products, the modules come with a three-year warranty.
