2. Măsuri de siguranță

2.1 Standarde de siguranță electrică

The equipment’s input power supply is single-phase AAC 220 V ±10%, 50/60 Hz. It must comply with safety standards and have a reliable protective grounding system with a protective grounding resistance of ≤4 Ω to prevent electric shock.

2.2 Standarde de siguranță a mediului

For indoor use only; avoid direct sunlight. Place on a sturdy, stable surface to prevent excessive vibration. Ensure the environment is free of dust, corrosive gases, and flammable or explosive materials. Keep away from strong magnetic and electric fields. Ensure adequate ventilation; leave at least 10 cm of space around the device for heat dissipation, and do not block the cooling fan vents. Operating Environment: Temperature 5°C to 35°C, relative humidity ≤65% RH.

2.3 Instrucțiuni de siguranță operațională

Do not operate the equipment or plug in or unplug the power cord with wet hands; Output must be turned off before connecting or disconnecting wires; do not touch the output terminals, internal components, the load, or load wiring while the equipment is operating; do not shut down the equipment directly while it is in output mode; turn off the output first before shutting down the equipment; if you notice an unusual odor, smoke, unusual noise, or overheating, immediately disconnect the power and do not continue operation.

①	Întrerupător
②	Voltage display window V; “—–” appears when the voltage exceeds the limit.
③	Current display window A; “—–” appears when the limit is exceeded.
④	Indicator lights. CC: Constant Current; CV: Constant Voltage; OVP: Overvoltage Protection Triggered; OCP: Overcurrent Protection Triggered
⑤	Memory Keys: The device can store 5 sets of configuration data, allowing for quick setup.
⑥⑦	You can use the number keys or the up and down arrows to adjust the settings.
⑧	V-Set: Press to set the voltage
⑨	I-Set: Press to set the current
⑩	OVP set—press to set the upper limit of the output voltage
⑪	OCP set—press to set the upper limit for the output current
10	After setting the values, press the ENTER key to confirm.
10	ON/OFF button: Tap to turn the power output on or off
10	Output terminals: Connect to your DC load, observing the correct polarity.

3.2 Introducere în panoul din spate

①	Power cord receptacle, with a fuse, for connecting the device to an appropriate power source
②	RS-232 communication port: If you need to use other software to configure and control the power output, please connect it to a computer.
③	Output terminals; these have the same function as the output terminals on the device’s front panel
④	The external sampling terminal, which is also connected to your DC load, allows you to obtain a more accurate load-side voltage. If you require high voltage sampling accuracy, please connect it; leaving it unconnected does not affect the DC power supply’s output functionality. Be sure to observe the correct polarity when wiring.
⑤	Sampling Selector Switch	The factory default is Side A, with internal sampling.
		If you have an external sampling terminal connected, switch to Side B for external sampling.

Note 1: External sampling uses a 4-wire configuration to eliminate cable voltage drop; internal sampling includes cable voltage drop.

Note 2: For the output terminals, connect either the front panel or the rear panel—one or the other is sufficient.

4. Funcționarea echipamentelor

4.1 Verification of OVP/OCP Settings

To ensure normal operation, the device is set to its maximum output value at the factory. For example, for the DC3005S, the OVP value is set to 30 and the OCP value is set to 5. If you need to review and adjust these settings, follow the steps below.

Instrucțiuni	notițe
①	Press the OVP Set button; the voltage display will show the currently set OVP value. If it is incorrect, you can use the numeric keys to reset it, then press the ENTER key to confirm.
②	Press the OCP Set button; the current display will show the currently set OCP value. If it is incorrect, you can use the numeric keys to reset it, then press the ENTER key to confirm.

4.2 Ieșire la tensiune constantă

Instrucțiuni	notițe
①	If you want the device to save the settings, press the corresponding memory button first.
②	Press the I-Set key to set the current to the maximum output value, or at least to a value sufficient for constant-voltage output. Use the numeric keys to set the value directly, then press the ENTER key to confirm.
③	Press the V-Set key to set the voltage to the desired rated value, then press the ENTER key to confirm.
④	Press the ON/OFF button to control the output; the CV indicator lights up when the output is active.

Note: If, during output, the CV indicator turns off and the CC indicator turns on, the set current value is insufficient to maintain the rated voltage of the DC load; you will need a DC power supply with a higher maximum output current.

4.3 Ieșire în curent constant

Instrucțiuni	notițe
①	If you want the device to save the settings, press the corresponding memory button first.
②	Press the V-Set key to set the voltage to the maximum output value, or at least to a value sufficient for constant-current output. Use the numeric keys to set the value directly, then press the ENTER key to confirm.
③	Press the I-Set button to set the current to the desired rated value, then press the ENTER button to confirm.
④	Press the ON/OFF button to control the output; the CC indicator light turns on when the output is active.

Note: If, during debugging, the CC indicator turns off and the CV indicator turns on, this indicates that the set voltage value is insufficient to meet the rated current output of the DC load. You will need a DC power supply with a higher maximum output voltage.

5. Întreținerea și îngrijirea zilnică a echipamentelor

5.1 Întreținerea de rutină

5.1.1 Curățare zilnică

Be sure to turn off the power and unplug the power cord before cleaning. We recommend wiping the unit with a soft, antistatic cotton cloth and a mild detergent; do not spray liquids directly onto the unit. Do not use chemical solvents such as benzene, toluene, or acetone.

5.1.2 Inspecții de rutină

Înainte de fiecare utilizare, verificați dacă cablul de alimentare și conexiunile terminalelor sunt fixate și nu prezintă urme de arsură; asigurați-vă că orificiile de ventilație ale ventilatorului nu sunt blocate; și după pornirea unității, verificați dacă luminile indicatoare și afișajul funcționează corect.

5.2 Specificații de stocare

5.2.1 Cerințe privind mediul de stocare

Temperatură: 5°C până la 35°C; umiditate relativă: ≤65% RH; mediu uscat, fără praf și fără gaze corozive.

5.2.2 Operațiuni de depozitare pe termen lung

Turn off the power and unplug all cables; clean the equipment and wrap it in dust-proof film; turn on the power for 10 minutes every 3 months to prevent moisture damage to the components.

Depanarea și rezolvarea problemelor comune

Simptome de eroare	Cauze posibile	Procedură
Nu se poate porni	Cablu de alimentare slăbit, siguranță arsă	Turn off the power and check the connection of the input power supply cord; turn off the power, troubleshoot for short circuits or overloads, replace the fuse with one of the same rating, and do not increase the current rating.
The settings are fine, but the OCP and OVP indicator lights are on.	Output Short Circuit, Output Out-of-Limits, and Device Overheating Protection	Stop output, check the output wiring, and retry after ruling out a short circuit; verify that the load’s rated voltage and current are within limits—for example, the maximum output voltage and current for the DC3005S model are 30V and 5A; shut down the unit, allow it to ventilate, clean the ventilation openings, and restart it after it has cooled down.
Ventilatorul nu se învârte	Acumulare de praf, defecțiune a motorului	Opriți alimentarea și curățați praful de pe ventilator; dacă problema persistă, vă rugăm să ne contactați pentru reparații sau pentru înlocuirea ventilatorului.
