Basic Mode of Operation
This power supply is designed to operate as a constant voltage
source or as a constant current source. Automatic crossover to
either mode of operation occurs when the load condition changes
Constant Voltage (CV), Automatic crossover & Constant Current
The power supply functions as a constant voltage source (CV) as
long as the load current is less than the preset current limiting
value. When the load current is equal to or greater than the preset
current limiting value, the power supply will automatically cross
over to the constant current mode, voltage will drop, (CC) will
show on the LCD display panel and it will operate as a constant
When the load current drops below the preset current limiting
value, the supply returns to constant voltage (CV) mode
Presetting Current Limiting Value (CC)
Switch on the power supply, adjust the output voltage to about 3V,
turn off the output terminal with push button 6, icon becomes
Short the black and red output terminals and turn on the output
terminal by 6, icon becomes adjust the current limiting
value to your desired value say x Amp by tuning knob 5. Turn off
the output terminal and take out the shorting connection.
The current limiting of power supply has been preset to x Amp for
the whole range of output voltage.
Connection and Operation Procedure
1. After checking with the rating label plug in to AC mains.
2. Switch on the power supply and the LCD display should be
on at the same time.
3. The (CV) icon should be shown on the display.
4. Turn to current volume knob 5 to maximum clockwise if you
do not require lower Current limiting value, otherwise do the
preset the (CC) limiting procedure.
5. Set your desired output voltage and then turn off the output
terminal by push button 6
6. Connect to your load positive to positive and negative to
7. Turn on the output terminal again and check if display shows
8. If display shows (CC), either your preset current limiting value
is too low or your load requires more voltage and current. You
need to re-access the voltage and current requirement of your
load and increase the voltage or current accordingly until (CV)
Tracking Output Over Voltage Protection ( OVP )
This is to protect the connected load in the event that the output
voltage control circuit mal-functions, the maximum output voltage
will not exceed 30% of the adjusted voltage value at the time of
Over Temperature Protection
When the temperature inside the power supply becomes higher
than a pre-determined value, the output voltage and current of the
power supply will automatically decrease to zero to prevent
damage to power supply. When the temperature inside the power
supply returns to about 65°C then the power supply will
automatically return to operation again.
Ecco il Manuale di quello che ho scelto, ovvio in inglese e non ci si capisce una mazza,
e anche traducendo con google ! una persona gentile ne usa gia uno e che mi spiega come si usa ?
O almeno cosa c’e scritto qui ?
Ma quindi come si tara la corrente costante ? nel video si vedeva che il tipo
metteva in CORTO piu e meno, ma qui non mi pare lo dica …o sbaglio ?
E la protezione “Tracking OVP” cosa sarebbe ?
Grazie x aiuto
