Artesyn's CPS250-M series AC-DC power supply features a universal 90 VAC to 264 VAC input and employs active power factor correction to minimize input harmonic current distortion and to ensure compliance with the international EN61000-3-2 standard. The power supply produces a tightly regulated main output and comes with a 12 VDC fan output as standard. The main output can deliver up to 155 W continuously with convection cooling, or up to 250 W continuously with at least 300 LFM forced air cooling. The output can be adjusted up to +10% of nominal setpoint through the trim pot.
The power supply’s main output has a hold-up time of 10 ms minimum when the supply is fed with a 115 VAC/230 VAC input and is delivering 225 W of output power. The CPS250-M series power supply is comprehensively protected against overvoltage, overcurrent, overtemperature, and short-circuit conditions. The power supplies operate from -20°C to +50°C ambient with startup at -40°C.
The units offer ITE and medical (2x MOPP) safety approvals including type BF medical applications. A universal 90 VAC to 264 VAC input and global safety approvals enable the CPS250-M series to be used almost anywhere in the world. These power supplies offer single output voltages of 12 VDC, 24 VDC, 36 VDC, or 48 VDC with a 10% trim range and additional 12 V fan output and optional 5 V standby output.
Active power factor correction (PFC) 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 make 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 in temperatures between -20°C up to +70°C with derating above +50°C and startup capability as low as -40°C. The CPS250-M series power supply is comprehensively protected against overload and overtemperature conditions. Artesyn offers a standard three-year warranty.
