High-Performance Programmable AC Power Supply with DC Output, 600VA to 6kVA
A test bench that needs both AC grid simulation and DC bench testing traditionally needs two separate instruments — until the load calls for exactly the compact, dual-mode approach the AFV-P series was built around. Preen's AFV-P is a high-performance programmable AC power source that switches to a genuine DC output mode from the same unit, spanning 600VA to 6kVA, covering both functions from a single instrument rather than requiring a dedicated DC supply alongside a separate AC source.
Beyond the dual AC/DC capability, the AFV-P includes built-in Power Line Disturbance (PLD) simulation supporting IEC 61000-4-11, -14, and -28 pre-compliance testing — voltage dips, short interruptions, voltage variations, and frequency variation testing that would otherwise require separate dedicated PLD simulation equipment ahead of formal compliance testing on certified equipment. THD is held under 0.3% at 5-100Hz, with response time under 300µs, and active PFC raises input power factor to 0.98, reducing reactive current draw from the supply.
The current generation is meaningfully more compact than its predecessor — 50% lighter and roughly a third smaller — relevant where bench space or portable test setup constraints matter as much as electrical performance. Standard connectivity (RS-232, RS-485, Ethernet, USB) covers most automated test integration needs, with GPIB and Analog available as options for labs standardising on those interfaces specifically.
