Slimline power modules simplify construction
The OPA2 and OPA3 modules extend the range of medical applications for the company’s NEVO 600 and NEVO 1200 series of modular power supplies.

The NEVO power supplies are designed for applications where size, weight and power density are key considerations. The addition of the OPA2 and OPA3 halves the number of isolated, configurable power modules required to achieve the same output. Instead of four isolated power modules required to achieve up to 600W and up to eight for the 1200W model, only number is reduced to only two and four, respectively. This minimises cable and link requirements, while simplifying construction. It also, says the company, increases reliability and, for most applications, reduces overall system costs.

There NEVO 600 (600W) and the NEVO 1200 (1200W), are both claimed to have footprint which is smallest in their class. The larger model measures 152.4 x 152.4 x 40.8mm (6.0 x 6.0 x 1.61inches), for a power density of 21W/in³. They are also lightweight, the NEVO 1200 weighs 1.2kg.

The NEVO 1200 include 90% efficiency and a standby power of less than 3W. It also has 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.

The power supplies can be used for diagnostic systems, medical robotics, dialysis / peristaltic pumps, laboratory and analysis equipment, incubators and other applications where high power levels are required in constrained spaces.

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

They reliable output (1 FPMH at 40⁰C at 80% load) modules offer load, line and cross regulation as well as over- current, voltage, temperature and short circuit protection. There is also a 5V, 10mA bias supply.

The modules are also approved to EN/IEC/ANSI 60601-1 and EMC EN60601-1-2 4th edition and are supplied with a three-year warranty.
