The OFI1200A Series from POWERBOX are Isolated AC-DC converters that step down an AC input voltage of 85-305 V to a DC output voltage of 12-48 V. These converters deliver a DC output power of 1200 W and have an efficiency of up to 92%. They have a switching frequency of 47-63 Hz and a power factor of 0.96. These converters have a power factor correction (PFC) feature and can be operated across a baseplate temperature range from -40 to +95 degrees C without the use of a fan. They have an optimized design to transfer heat to the baseplate making them suitable for non-ventilated applications as in sealed enclosures. These converters are available in a chassis mount unit that measures 142 x 40 x 260 mm and are ideal for harsh industrial applications.
