1.3 Safety Instructions
1.3.1 Transportation
When transporting the product, please ensure that the original packaging is used to
prevent damage to the product.
P.5
1.3.2 Ambient Conditions
The product is designed for indoor use.
Condensation may occur after the product was shipped, or
subject to a sudden change in an atmosphere of temperature or
humidity. Do not use the product for at least two hours to
ensure it is dry before turning it on.
Do not place the product in high humidity area.
Do not expose the product to direct sunlight or any heat source.
Do not block the ventilation openings at the enclosure of the
product.
Do not place any heavy objects on the product.
1.3.3 Installation
The product is constructed to Protection Class I. Connect the product
to an earthed wall receptacle with a power cord approved by relevant
International Standards.
The product is rated at AC input 85~264V, 47~63Hz mains.
1.3.4 Operation
Be careful! A change from open circuit to short circuit could result in
high current sparks and cause injury to eyes. An instantaneous
power circuit change from short to open may induce high voltage and
arcing, causing shock and injury to eyes.
P.6
1.3.5 Service & Maintenance
The product operates at hazardous high voltage (near DC 380V or
AC 267V). Only qualified personnel can carry out servicing or
maintenance.
Always use a properly rated voltage sensing device to confirm that all
power is off.
Before attempting any service, disconnect the product from all power
supply and ensure that no harmful residual voltage remains at the
terminals of bulk capacitors.
Replace the fuse only with the same amperage and voltage ratings
to avoid risk of fire.
This is a Class A device which may cause RF interference
within the home.
The product should only be operated when the case is securely
closed, with all screwed tightened.
While operating the product, the wearing of metal or other
conducting jewelry such as chains, bracelets, rings, etc. is not
recommended.
1.3.6. Storage
Location: Indoor
Relative Humidity: <80%
Temperature: -10℃ ~ 70 ℃

3. Operation
3.1 General
C³V Series integrates two power supplies – constant voltage (CV) and constant
current (CC). These two power supplies exclusively operate, and outputs do not
exceed user-preset limit. CV or CC states are dependent on and limited by the
comparison between load conditions and C³V Series settings.
3.2 Description
C³V Series utilizes the Up and Down keys to set desired voltage and current outputs.
Real time voltage and current are displayed on the Display Meter. Pressing the Enter
key momentarily switches between different operation modes.
The V-LED and A-LED indicate the selected operation mode. The CC-LED indicates
that the power supply currently being in CC Output (Reading) mode.
3.3 Output (Reading) Mode & Setting mode
Output (Reading) Mode
Upon AC powering on the C³V Series, the unit automatically enters “Output (Reading)
Mode” and the green V-LED illuminates. The values shown on the Display Meter refer
to the last used data. Pressing the Enter key momentarily, you can read the voltage,
current (if a load was connected) and internal temperature. The outputs are controlled
by preset CC and CV values, as shown in the graph below.
P.10
Setting Mode
By pressing the Enter key for 3 seconds, you will hear a short beeping sound. This
indicates that the C³V Series has entered “Setting Mode”. “The V-LED OR A-LED
“ AND “ the respective decimal point ” will be blinking on the 4-digit Display Meter.
Use the Up or Down keys to set the desired voltage or current. Press the Enter key for
3 seconds to confirm. The C³V Series now reverts to “Output (Reading) Mode”. The
adjusted value is displayed in the graph below.
