AC Power Source
Programmable AC power sources from Preen and ActionPower, spanning compact bench units to megawatt-scale facility systems for grid simulation, compliance testing, and general R&D.
Preen
Available as a Containerized / IP54 Option
Every Preen AC power source below can be built into a customized outdoor container or upgraded to an IP54-rated enclosure, following the same approach as Preen's dedicated BPS shore power range — useful for ports, construction sites, remote installations, and other high humidity, heat, dust, or corrosion-exposed environments. Standard indoor chassis remain the default; contact Finch to configure a containerized or IP54 version for your application.
AFV Series
High-Power Programmable AC Power Source, 10kVA to 1600kVA
Preen's core high-power AC source line, scaling from single-phase 10kVA bench units to three-phase 1600kVA facility-scale systems for home appliance, motor, and industrial R&D and compliance testing.
