Page 5: Normal Mode
Preset Mode In this mode, the Rear Control Light is ON to indicate that the panel V & I controls are de‐ activated. There are three preset outputs P1/ P2/ P3 available using the Recall Selection Switch (9) The preset values are factory set as shown in the table below. The user can change these output settings; please refer to the next paragraph. Recall No. Output Voltage Output Current P1 5V Maximum P2 13.8V Maximum P3 55V Maximum Set Mode Enter the Set Mode by pushing Switch (8) to the Set Mode slot; the power supply is now ready to be preset. To define the preset output P1/ P2/ P3 Move the Recall Switch (9) to position P1, P2 or P3 Adjust the front panel voltage control knob to set the desired voltage value Adjust the front panel current control knob to set the desired current limit value Repeat the procedure for the remaining recall locations P1, P2, P3 if desired. Move Mode Switch (8) from Set to Preset position to confirm the settings. Set Mode Notes: All presets are saved after the power supply has been switched off. Always check the output voltage of the Preset before connecting to a Load. To check the preset values: Move the Mode Switch (8) to the Preset position and then set the Recall Switch (9) to P1, P2 or P3. The V and I settings for the corresponding RECALL P1, P2, P3 memories will be shown on the panel meter. DCP60‐EU‐IT v1.4 9/13 ... -

Page 7: Operation
Operation Nota: La tensione massima in uscita del DC60 è 60VDC e la corrente nominale totale (Aux. + principale) è 10A Powering the Supply Check the rating label of the power supply and ensure that it complies with the AC mains voltage that is to be used. Connect the power supply to the AC Mains using the provided power cord. Ensure that the Mode Switch (8) is set to the Normal Mode position. The Model DCP60 requires a 110VAC power source and the DCP‐220 requires a 220V power source. Switching the Power Supply ON and Self‐Test Information The power supply will perform a series of self‐tests when it is switched on. The LED and other indicators on the front panel will illuminate in sequence. When the cooling fan is being checked, a high speed wind sound can be heard. After the self‐tests, the CV, V and A LED indicators are lit displaying voltage and 0.0 current. To find the CC current level, turn the current control knob one click in either direction. The current display returns to 0.0 after a few seconds. The table below details the self‐test sequence: Self‐test displays Test Software version Segment check C.V. Indicator check C.C.

Page 8: Using The Control Knobs
Using the control knobs The rotary encoder control knobs have fine and coarse tuning with ‘clicking’ movement. Push the knobs to toggle between coarse and fine tuning, notice the subtle changes in brightness of the related LED. Adjust the knobs to the desired values by using coarse and then fine tuning. The display will resume its normal brightness after few seconds to confirm an adjustment. Connecting the Power Supply and running a test Connect the equipment under test to the power supply. Red (+) is connected to the positive polarity input of the equipment and Black (‐) is connected to the negative polarity input of the equipment. Switch ON the power supply first; the panel meter & green CV Indicator should illuminate. Next, switch ON the equipment under test; the panel meter & green CV Indicator should remain lit in green. Testing can now begin. When finished, switch OFF the equipment under test first and then switch off the power supply.

Per esempio (vedere il disegno di seguito), Passo 2 Tensione, scorrere la barra per impostare il livello d'uscita desiderato Quando il cursore è attivo è possibile utilizzare le frecce direzionali destra e sinistra della tastiera per regolare precisamente le impostazioni. Impostare la durata per questo passo come mostrato nel disegno in basso. Il range di tempo va da 0 a 9 ore/59 minuti/59 secondi. Cliccare sui pulsanti freccia su/giù o digitare il valore direttamente. Se il tempo è impostato su ‘0’ il passo sarà saltato. Impostare il ciclo di lavoro (numero di volte in cui sarà avviata l'intera sequenza) come mostrato di seguito. Range disponibile da 0 a 999 cicli. Usare il cursore o digitare direttamente nel campo per impostare il numero di cicli. Impostare il valore del ciclo su zero per mandare in ciclo la sequenza indefinitamente. Cliccare sul pulsante RUN per avviare il ciclo. Cliccare sul pulsante STOP per arrestare il ciclo. Cliccare sul pulsante CLEAR TABLE per cancellare le impostazioni. Avvertenza: Quando la sequenza è completa, le impostazioni in uscita torneranno a quelle visualizzate nella parte sinistra di questa finestra. Verificare che le impostazioni siano corrette per evitare danni all’UUT. Memoria Preimpostata Interna La capacità di preimpostazione dell'interfaccia remota del PC semplifica il noioso processo di digitazione in gruppi di voci. Dal momento in cui tutti i dati sono visualizzati contemporaneamente sul monitor del PC, la possibilità d'inserire dati in modo scorretto è molto ridotta. Dati di gruppi differenti possono essere classificati, memorizzati, esportati e recuperati per l'uso in qualsiasi momento. Inoltre, i dati recuperati appariranno di colore rosso se superano i limiti preimpostati di tensione/corrente. Cliccare su ‘Clear Table’ per cancellare tutti i dati sulla Tabella del Display per preparare per nuovi dati. Cliccare su ‘Read for PS’ per recuperare dati dall'Alimentatore.

Page 21: Otp: Over Temperature Protection
OTP: Over Temperature Protection There is a thermo sensor inside the unit to monitor and prevent the unit from unduly heating internally. When an OTP error occurs, there is no output and the following warning will appear on the LED display. When this warning appears, switch off the unit and remove all loading. Check the load and output setting. Allow the unit to cool for at least 30 minutes. Check to see if any ventilation holes are blocked, also check that there is sufficient clearance around the power supply. Listen carefully for the short wind sound emanating from the cooling fan when the unit is switched ON again. If the wind sound is not detected, the fan may be faulty; do not use the power supply in this case, contact the customer care department or the agent from the point of purchase. OLP: Over Load Protection Normally the overload protection is sustained by the CC constant current mode. When the CC mode fails and goes undetected, serious damage to the test piece or load may occur. The OLP is used to minimize the extent of damage to the loads in the event of power supply failure. Switch off the power supply as soon as this warning is seen (as shown below). To reset this warning, switch off the unit and remove all loading. Switch the unit back on again and double check with caution. If this problem persists, please contact the customer care department or and consult with the agent at the point of purchase.
