eration, service, and repair of this product. 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 product.
Preen assumes no liability for the customer‘s failure to comply with these require-
ments.
1) BEFORE APPLYING POWER
Verify that the product is set to match with the power line input.
2) PROTECTIVE GROUNDING
Make sure to connect the product to the protective ground to prevent an elec-
tric 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 product in the presence of flammable gases or fumes.
5) DO NOT REMOVE THE COVER OF THE PRODUCT
Personnel who operate the product must not remove the cover of the product.
Component replacement and internal adjustment can be done only by qualified
service personnel.
WARNING
LETHAL VOLTAGES. The product can supply 440V peak at its output. DEATH on
contact may result if either the output terminals or the output circuits connected
to the output are touched when the product output is on.

2Installation
2.1 Inspection
After unpacking the product, please inspect any damage that may have occurred
during the shipment. Save all packing materials in case the product has to be re-
turned one day.
If any damage is found, please file a claim with the carrier immediately. Do not return
the product to the factory without obtaining the prior Return Merchandise Authori-
zation (RMA) acceptance from Preen.
2.2 User Preparation
Be sure the device is connected to the power line input that meets the specification.
The device must be installed in an air-circulated area, so that the fans built-in are
able to ventilate the heat generated by components properly. The ambient temper-
ature should be controlled within 40C.

AFV-P Series High Performance Programmable AC Power Supply
10
2.2.1 Notice for installation
1. The device must be installed on horizontal grounds, and should be located near
the load so that the connection is as short as possible.
2. Leave sufficient space around the device for ventilation and maintenance (refer
to Figure 2.1). Do not block the cooling fan opening in case of internal tempera-
ture getting too high and having bad impact on product life.
3. The device should be located in proper ventilation, the ambient temperature
and humidity should not be high. Stay away from liquid, flammable gases, cor-
rosive substance, heat sources or direct sunlight. Keep the opening free from
dust.
4. The operating environment should be free from dust, volatile organic com-
pounds, high salinity or corrosive substance.
5. Do not operate the device outdoor.
6. Use correct cable selection and a proper power distribution to ensure the safety
of the device and the users.
Figure 2.1 The required space for the device.

2.3 Input Connection
The input terminals are located on the rear panel of the product (see Figure 2.2). The
input power cord must be rated at least for 85C. The input power cord must have
rated current which is greater than or equal to the maximum input rated current of
the product.
See Figure 2.2 and do the following procedures step by step:
1. Remove the safety cover from the rare panel of the product.
2. Screw the power cord to the input terminals of the product as follows,
2.1 green or yellow wire to the terminal “G” of the input terminals;
2.2 white or blue wire to the terminal “N” of the input terminals; and
2.3 black or brown wire to the terminal “L” of the input terminals.
3. Slip the safety cover over the input terminals, and secure the cover with two
screws.
WARNING
Protective Grounding. To protect users, the wire connected to terminal “G” (that
is GND) must be connected to the earth ground. Under no circumstances shall
this product operated without an adequate protective grounding connection.
Installation of the power cord to the product must be done by a professional and in
accordance with local electrical codes.

2.4 Output Connection
The output terminals are located on the rear panel of the product (see Figure 2.3).
The terminals “N” and “L” of the output terminals are connected to the load. To
match the safety requirements, the safety cover for the output terminals must be
fastened. The wires to the load must be sufficiently large gauges, so they will not
overheat while carrying the output current.
Figure 2.3 Output terminals
Figure 2.4 Output terminals to the load
NOTICE
When output voltage contains DC composition, Terminal “L” of the output ter-
minals indicates the “+” terminal; terminal “N” of the output terminals indi-
cates the “-” terminal.

2.4.1 Notices for DC output of AFV-P Series
1. A typical DC supply could have better ripple and noise performance than the DC
output of AFV-P series, mainly because as an AC power supply, AFV-P series
doesn't equip with high-capacity filter capacitors. To add a high-capacity filter
capacitor, for instance 50uF, ensure to connect a diode at the DC output ter-
minal in serial first, and then connect the high-capacity capacitor in parallel.
Do not directly connect the high-capacity capacitor in parallel. Doing so could
cause output unstable and trigger the product protection.
2. A typical AC power supply will shut down the output if the output current were
to exceed the rated value. AFV-P series could still maintain the output current
when exceeding the set value of maximum current by enabling the over current
foldback(OC-FOLD) mode.
The response time for OC-FOLD mode is 1.4S, while for a typical DC supply op-
erating constant current (CC) mode the response time is at the millisecond (ms)
level.
