The Medical Versatile Power Series allows customers to use an AC-DC power supply range in multiple applications where standardizing on a single reference power platform is key for simplifying installation footprints rather than stocking many different power supply variants with different mechanical installation requirements.

Common features across the affordable Medical Versatile Power Series include the latest approvals for safety IEC 60601-1 (ed 3.1 BF rated) and EMC immunity IEC 60601-1-2 (ed 4) for future proofing designs. Other key features include universal input range, output voltages from 12 to 58VDC for use worldwide.

The power supply family has low inrush current of 25A maximum to allow parallel AC primary connection of up to 3 units when using the load share function to support more demanding applications, delivering up to 2700W. There is a +/-3% output voltage adjust and remote sense to assist with voltage drop on longer cable runs. The signal I/O includes; power good signal, remote on/off, load share, current limit and 5V standby for control and monitoring. A wide range of mechanical variants are available: U channel, covered, slotted covered (fully covered only for 1000W) to suit your mechanical installation preferences. The 600 and 800W models allow peaks of up to 1000W for 500ms, great for motor driving and cost optimising for dynamic loads.

The 600W and 800W models measure 5 x 8.5 x 1.61 inches and the 1000W unit has dimensions of 5 x 9.51 x 1.61 inches, both suitable for 1U installations. All models feature over temperature protection, over voltage protection, over current protection and short circuit protection and an operating temperature from -40 to +70°C (with derating).

“Our new medical versatile power series provides medical system designers simple to integrate power supplies in industry standard 1U height offering not only a cost-effective system power supply but also form fit and function replacements for other manufacturers’ products in 19” racks. The units are perfect for body floating applied part applications where
