1 General information
1.1 Introduction
The AFV
+
series is a high power programmable AC power source utilizing advanced
PWM technology to deliver power with THD ≤0.5% and up to 2000kVA. The output
frequency are 45~500Hz (type A) and 45-120Hz (type B) with accuracy of ± 0.02%,
and user can select 300-840Hz (type C) option to expand the frequency. The AFV
+
series is ideal to simulate different region’s voltage and frequency conditions, and
can cover applications for renewable energy, EV charger, motor, medical equipment,
and EMC laboratory.
The AFV
+
series features STEP and RAMP programmable functions to easily simulate
single or continuous output changes. Three phase independent adjustment, optional
remote sensing and optional phase angle adjustment all provide convenient control
to simulate different kinds of line disturbance. These features are ideal for test
applications of R&D design verification, quality assurance and production checks. For
remote control, the AFV
+
series has standard RS-232/RS-422/RS-485 interface card
and optional GPIB and Ethernet interfaces for easy setup and programming.

NOTICE
If the Power Factor (PF) corresponding to the AC output is less than 0.775, 100%
output current can be achieved under 0%-100% output voltage, which can be
applied to any AFV
+
Series product model and any output voltage range of the
product.
