Preen AFV Series
High-Power Programmable AC Power Source, 10kVA to 2000kVA
Compliance and R&D testing against voltage and frequency disturbance standards needs more than a stable, clean AC supply — it needs a source that can deliberately reproduce the disturbances equipment is required to tolerate: voltage sags, frequency variation, and multi-step transient sequences. Preen's AFV series is built as the core platform for this, scaling from single-phase 10kVA bench units to three-phase systems up to 2000kVA.
Built-in STEP and RAMP programming — supporting up to 24 steps or 12 ramp sequences — lets a test programme reproduce a defined disturbance profile automatically rather than manually stepping through voltage and frequency changes, relevant for repeatable compliance testing and R&D work across home appliance, motor, and industrial applications where a specific disturbance sequence needs to be applied consistently across multiple test runs. Standard frequency coverage is 45-120Hz, with 45-500Hz available as an option for applications needing a wider range.
Connectivity is comprehensive as standard: RS-232, RS-485, and Ethernet come standard, with GPIB, Analog, and USB available as options — covering the range of automation and remote-control integration a test lab is likely to need without requiring a higher model tier just for connectivity. A full protection suite (OVP, UVP, OCP, OPP, OTP, and short-circuit protection) is standard across the range, and a 7-inch or 10.1-inch touch screen provides direct manual control alongside the automated programming capability.
