l)
Do not place heavy objects on the device housing.
m)
Avoid impacts or incorrect handling to prevent
damage to the device
n)
Some parts of this appliance can get very hot. To
avoid injury, be careful when touching these surfaces.
o)
Do not use the power adapter under the full load for
EN
a long period of time; it may cause damage to the
device.
p)
The output voltage of the power supply should
not exceed the input voltage of the device being
powered. Excessively high voltage may damage the
powered device.
q)
Before each change of the power adapter operation
mode, first disconnect the connected external load
wires.
r)
Do not switch the device on and off too often, as
this may shorten its lifespan. Each time the power
is turned on; there is a 2-3 second transient
preparation time. After the power is turned off, the
transient preparation is 1-2 seconds.
s)
The device is intended for indoor use.
ATTENTION! Despite the safe design of the device
and its protective features, and despite the use of
additional elements protecting the operator, there
is still a slight risk of accident or injury when using
the device. Stay alert and use common sense when
using the device.
3. USE GUIDELINES

3.2. PREPARING FOR USE
Appliance location
The temperature of environment must not be higher than
40°C and the relative humidity should be less than 75%.
Ensure good ventilation in the room in which the device
is being used. There should be at least 10 cm distance
between each side of the device and the wall or other
objects. Keep the device away from hot surfaces. Operate
the device on an even, stable, clean, fire-proof and dry
surface and out of the reach of children and persons with
mental disabilities. Position the device such that you always
have access to the power plug. The power cord connected
to the appliance must be properly grounded and
correspond to the technical details on the product label!
3.3. DEVICE USE
Operation
1)
Place the device on a stable surface and connect the
power cable to a power source in accordance with
the power supply name plate.
2)
Study the power parameters of the device when
connected to the power supply.
3)
Turn the device on by pressing the On/Off (5) button.
4)
Depending on the needs, the voltage or current limit
should be set as follows:
a) Setting the voltage value limit:
• Turn the current adjustment knobs (2) and (3)
clockwise to the maximum.
• Set the preferred value using the voltage
adjustment knobs (7) and (9).
• Switch off the device pressing the On/Off button
(5).
b) Setting the current limit:
• Set the voltage value between 3 ÷ 5V using knobs
(7) and (9).
• Turn the current adjustment knobs (2) and (3) to
a minimum.
• Switch the appliance off by pressing the On/Off
button (5).
• Connect the positive (12) and negative (10) poles
using the test cable.
• Switch on the device by pressing the On/Off
button (5).
• Use the current adjustment knobs (2) and (3) to
set the preferred value.
• Turn the voltage control knobs (7) and (9) to the
maximum.
• Switch off the device pressing the On/Off button
(5).
• Disconnect the pole connection cable.
PLEASE NOTE! do not short circuit the poles for too
long, perform the operation as quickly as possible.
When there is a short in the power supply, you will
hear a slight noise, which is normal!
5)
When the parameters have been set, connect the
external load to the appropriate poles (+) and (-).
6)
Switch the device on using the On/Off button (5).
7)
The device automatically switches between CC and
CV modes depending on the load. For example,
06.03.2019
EN
for a set current limit of 10A, if the external load
is supplied with current less than the current value
which has been set, then the power supply will
always be in CV mode. If, on the other hand, it is
supplied with a current higher than 10A, the charge
will automatically switch to CC mode.
8)
The device has thermal protection. Should the
protection become active, disconnect the device
from the power supply, let it cool down and remove
the cause of the protection having been tripped.
Then, the device can be restarted.
9)
The device has overload protection (OCP) and
overvoltage protection (OVP). Should the protection
become active, disconnect the external load and
verify that its power supply parameters correspond
to the charger output parameters.
10)
When you have finished work, switch off the device,
disconnect the external load and disconnect the
device from power supply.
3.4. CLEANING AND MAINTENANCE
