The IPAC2000 series of regenerative AC electronic loads are used for generators, AC sources, inverters, UPS/EPS, charging piles, controllers and switch segment devices, server AC devices, power electronic equipment testing and aging. The AC feedback electronic load is a power electronic conversion device based on a two-stage conversion architecture of power frequency isolated IGBT rectification and inverter. It has high reliability and programmability; it can realize local control through internal control and communication modules And remote control. The internal sampling circuit can quickly detect over current, overload, over voltage and output short circuit, and automatically protect and cut off the output, and send out an alarm. The power inverter unit uses integrated laminated busbar technology and modular configuration to improve quality reliability and stability. The equipment adopts touch screen display and control, and the operation is simpler。
◆ Using the principle of PWM rectification + PWM inverter, it can realize energy feedback to the grid, and has outstanding advantages such as energy saving and consumption reduction, and green environmental protection.
◆ The PF value can be set between 0.3 and 1 (leading or lagging).
◆ It has a wide voltage input range and a wide frequency input range.
◆ With constant resistance, constant current, and constant power working modes.
◆ Using PWM synchronous rectification, combined with software algorithm PFC correction control, to achieve power factor (PF) ≥ 0.99.
◆ ITHD≤3%.
◆ It has complete grid-connected protection functions: over frequency, under frequency, over voltage, under voltage, overload, etc. To
◆ Three-phase has three-phase independent adjustable function, (harmonic adjustment option).
