Operating at an efficiency as high as 90%, the N-0275 Series of PFC ac/dc power supplies feature digital power management and optional I2C-based PMBus capability. The 275-W open-frame devices have an onboard microcontroller monitoring parameters such as output voltage and current, auxiliary output voltage (nominal 12 V), transformer and ambient temperature, as well as fan speed.
Delivering a power density of 12.22 W/in.3, the supplies have active inrush current protection, and remote on/off. The devices can deploy in groups of 4 using the I2C bus.
