They are specialized electrical devices that convert direct current (DC) into alternating current (AC) in a unique manner, producing a split-phase output; this type of inverter is designed to mimic the electrical supply typically found in residential and some commercial settings, where two separate AC waveforms with a phase difference are provided to power various appliances and systems.

This means that the power supply can “start-up” or be “turned-on” with an ambient temperature as low as -40°C (below the -20°C spec) and deliver 100% of its rated power, however, the power supply’s output regulation, hold-up time, ripple & noise, and other specifications cannot be fully guaranteed until the power supply warms up to at least -20°C.
