Suitable for non-patient contact medical applications, with no-load power consumption below 0.8W, 5 years’ warranty and EMI Class B level compliance, they are also suitable for all types of ‘green’ medical equipment or electrical devices. Additionally, they meet energy-saving requirements for end-user systems.

The MSP-600 series has a universal ac input of 85 – 264V, with output voltage options ranging from 3.3V to 48V. Operating efficiency is as high as 89 percent. An internal long life dc fan can be activated for forced air cooling, allowing full-load operation in -40°C to +50°C ambient temperatures, extending to +70°C with suitable de-rating.

Other standard functions include short circuit, overload, over-voltage and over-temperature protection, 300Vac input surge immunity for 5 seconds, remote ON/OFF control, remote sense, fan ON/OFF control and dc OK signal output. With built-in active power factor correction, the units’ power factor exceeds 0.94.

Higher wattage applications can be accommodated by paralleling up to four MSP-600-24, -36 or -48 models for a total power delivery of up to 2,400W. The units also have a 5V/0.3A standby output. The MSP-600 series complies with global medical certificates to UL/CUL/CB/CE, ensuring user safety.
