Yetger Energy's Programmable AC Source Series delivers precision AC power for test, calibration, and simulation applications — spanning 1kVA to 3.6kVA with selectable 50Hz, 60Hz, till 1000Hz output frequencies in a single compact platform.

Designed for labs, avionics test benches, and industrial QA lines, this series generates a clean, programmable AC waveform from a wide-range DC or single-phase AC input, using a fully digital control architecture  for tight voltage regulation, low THD, and fast transient response.

• Power Range: 1kVA / 1.5kVA / 2kVA / 3kVA / 3.6kVA models on a common platform
• Frequency Range: 45Hz–1000Hz programmable, with dedicated 50Hz, 60Hz, 400Hz and 1000Hz (MIL-STD-704 aviation) presets
• Output Voltage: Programmable 0–130V / 0–260V AC (auto-ranging), single-phase
• THD: <3% at full linear load
• Regulation: ±0.5% voltage, ±0.01% frequency
• Waveform Control: Pure sine, with harmonic injection/distortion simulation modes for compliance testing
• Protection: OCP, OVP, OTP, short-circuit and soft-start current limiting
• Interfaces: Front-panel touch/keypad control, RS-485 Modbus RTU, USB, optional LAN/RS-232
• Metering: Real-time V/I/F/P/PF display with datalogging

• Avionics and defence equipment testing (400Hz aircraft power simulation)
• Export/import product compliance testing (50Hz ↔ 60Hz region simulation)
• EMI/EMC and harmonic distortion testing
• Burn-in and production line QA
• Calibration lab reference sources

Yetger Energy's 3-Phase SFC Series converts standard 3-phase AC mains into clean, programmable 3-phase AC output at frequencies and voltages your equipment actually needs — built for aviation ground support, industrial testing, and export/import power simulation.

Our 3-phase SFCs use a fully digital IGBT/SiC H-bridge architecture with LC output filtering, driven by digital control platform, to deliver stable, low-THD 3-phase power from a 3-phase AC input — with frequency and voltage fully decoupled from the incoming mains.

• Power Range: 10kVA to 100kVA+ (scalable, modular platform)
• Input: 3-phase, 380V/415V/480V AC, 50/60Hz
• Output Frequency: Programmable 45Hz–500Hz, with dedicated 50Hz, 60Hz, and 400Hz (MIL-STD-704F aviation) presets
• Output Voltage: Programmable 3-phase, Y or Delta configurable, auto-ranging
• THD: <3% at full linear load
• Regulation: ±0.5% voltage, ±0.01% frequency
• Topology: 3-phase IGBT/SiC H-bridge with active/passive LC filtering, SPWM/SVPWM switching
• Protection: OCP, OVP, OTP, phase-loss, short-circuit, soft-start inrush limiting
• Interfaces: Touch/keypad HMI, RS-485 Modbus RTU, USB, optional LAN/SCADA integration
• Metering: Real-time per-phase V/I/F/P/PF display with datalogging and event logs

• Aircraft ground power units (400Hz GPU simulation, MIL-STD-704F compliance)
• Naval and defence platform power conversion
• Export/import equipment testing across 50Hz/60Hz regions
• Industrial 3-phase load testing and burn-in
• Frequency conversion for imported machinery (motors, CNC, process equipment)
