Import 500va-12000va Ac Power Supply An61 Series — Buy in wholesale FOB from Supplier in China

The AN61 series from Ainuo Instrument is a programmable AC power supply line spanning 500VA to 12000VA output capacity, built on principle of sinusoidal pulse width modulation (SPWM) with digital signal processor (DSP) control. It delivers AC, DC, and AC+DC output modes with stated voltage accuracy of 0.4 percent, total harmonic distortion below 0.3 percent, and load effect under 0.5 percent. The unit can source six times peak current for inrush testing and supports programmable impedance together with harmonic and flicker measurement functions for IEC pre-certification work.

Internal architecture combines high-frequency switching power conversion with DSP-based waveform generation, enabling arbitrary waveform amplification through an external port. Users can record field waveforms, replay them through the AN61, and superimpose harmonics or simulate grid anomalies including sags, swells, short circuits, and jitter. The steel enclosure houses PCB assemblies with electronic components, with cooling and layout optimised for continuous operation in laboratory and production-line environments. Standard IEC test coverage includes IEC61000-4-11, -4-13, -4-14, and -4-28 immunity tests, plus IEC61000-3-2 and -3-3 harmonic and flicker measurement when paired with the internal or external power analyser.

Target buyers are power electronics R&D groups, avionics test houses, appliance manufacturers conducting type approval, and quality assurance departments needing programmable grid simulation. Applications extend to switching power supply inrush characterisation, IEC standard pre-certification, production-line burn-in, and academic research on power quality. The 500VA entry model suits bench-top development, while the 12000VA top end addresses three-phase or high-current test scenarios. Buyers should confirm with Ainuo Instrument whether the specific VA rating, voltage range, and phase configuration they need are available from stock or require factory order lead time.

Ainuo Instrument is headquartered at No.134 Zhuzhou Road, Qingdao, Shandong Province, China, 266101. The supplier operates within the electrical equipment and industrial instrumentation sector, offering the AN61 series as part of a broader product portfolio. The company profile does not disclose year of establishment, factory floor area, employee count, or annual revenue, so any such figures must be requested directly during qualification.

The supplier holds a harbor trust tier but shows a zero percent response rate with zero average response hours on the listing. This signal suggests buyers may experience delays in quotation or technical support, and should plan accordingly by using multiple contact methods or engaging through recognised trade channels. No ISO 9001, ISO 17025, or other quality system accreditation is mentioned in the source material, making supplier audit and reference checks advisable before large commitment.
