SAFETY SUMMARY
Danger
Dangerous high voltages exist inside this machine. Do not open any covers of this
machine unless authorized and done by trained technicians. Otherwise, electrical
shock to persons may happen.
In case the machine needs to be moved or re-wired, all electricity to the machine
must be disconnected and removed. After electricity is removed, please wait for at
least 20 minutes before touching any live parts of this machine or electrical shock
may occur: the electrical charges on the bulky capacitors inside the machine need
some time to be fully discharged.
For optimal safety protection to the users, this machine must have solid
connections to the earth. Do not use this machine if it is not grounded.
In case of fire, use an extinguisher with powder chemicals instead of liquid agents.
Electrical shock may occur if liquid extinguishing products are used.
Any foreign objects and/or liquid are strictly prohibited from entering to the inside
of this machine.
Caution
Storage and operating environment have a certain degree of influence on the life
and reliability of this product. Therefore, avoid placing and/or operating this
machine in environments with the following:
(a) Having extreme ambient temperature or humidity that exceeds the allowable limit
stated in the specification, temperature: 0℃-45℃, humidity: 0-90%.
(b) Having direct sunlight exposure, or being near a heat source.
(c) Places that tend to be vibrated or hit by other objects.
(d) Having heavy dust, heavy salt, corrosive chemicals or inflammable chemicals in the
air.
Please keep air ventilation inlets and outlets clear and clean. Obstruction on the
inlet or outlet will have significant negative impact on the machine’s quality and
reliability.
If the machine will not be used for a long time, please store it in a dry and clean
environment with temperature in the range of -40℃-+70℃.
This machine is composed of many delicate and precision devices. Please do not
open any covers of this machine unless authorized and done by trained technicians.
Warranty is voided if the quality seal is broken.

1-2
The following general safety precautions must be observed during all phases of
operation, service, and repair of this equipment. Failure to comply with these
precautions or specific WARNINGS given elsewhere in this manual will violate safety
standards of design, manufacture, and intended use of the equipment.
Preen assumes no liability for the customer‘s failure to comply with these
requirements.
1) BEFORE APPLYING POWER
Verify that the equipment is set to match with the power line input.
2) PROTECTIVE GROUNDING
Make sure to connect the equipment to the protective ground to prevent an
electric shock before turning on the power.
3) NECESSITY OF PROTECTIVE GROUNDING
Never cut off the internal or external protective grounding wire, or disconnect
the wiring of protective grounding terminal. Doing so will cause a potential
shock hazard that may bring injury to a person.
4) DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the equipment in the presence of flammable gases or fumes.

5) DO NOT REMOVE THE COVER OF THE EQUIPMENT
Hazardous voltages may be present when the covers are removed. Component
replacement and internal adjustment can be done only by qualified service
personnel.
Caution
LETHAL VOLTAGES. The equipment can supply 310V at its output. DEATH on
contact may result if either the output terminals or the circuits connected to the
output are touched when the power is applied.

1General 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.
Figure 1.1 V/I characteristic curve for the AFV+series
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.

NOTICE
When choosing AFV+series output frequency 45-500 Hz, the output power will be
influenced as the information above (Figure 1.2 &1.3). We would suggest the users
to select the ideal model base on their needs or higher output power, in order to
avoid the limitations.
