Artesyn Embedded Technologies has introduced the CPS250-M series, which delivers 250 W with forced-air cooling and 155 W with natural convection. The CPS250-M series follows the industry standard 2 X 4 inch form factor (50.8 X 101.6 mm) and is just 1.29 inches high (32.7 mm). The CPS250-M series offers 93% typical efficiency and less than 500 mW of no-load power dissipation.
The units offer ITE and medical (2x MOPP) safety approvals, including type BF medical applications. A universal 90 to 264 Vac input and global safety approvals enable the CPS250-M series to be used almost anywhere in the world. The power supplies offer single output voltages of 12, 24 or 48 Vdc, with a 10% trim range, an additional 12 V fan output and optional 5 V standby output.
Active power factor correction compliant to IEC 61000-3-2 for EMC, a built-in Class B EMI filter and compliance to edition 4 of the IEC 60601-1-2 medical EMC, makes it easier to integrate the CPS250-M series into customer equipment, especially healthcare, dental, laboratory and medical applications. An optional cover kit, the LPX100, provides greater physical and electromagnetic protection if required.
The units can operate within a range of 20° to 70°C, with derating above 50° C and startup capability as low as –40° C. The CPS250-M series power supply is protected against overload and overtemperature conditions.
