RF4 3005D 3005PRO Digital Smart DC Power Supply 30V 5A 150W

RF4 RF-3005D / 3005PRO 30V 5A 150W Regulated Adjustable LCD Digital Display Smart DC Power Supply. 110V/220V multi-functional switching regulated DC power supply for phone motherboard soldering repair, factory, laboratory, university and laptop maintenance, electronic production line, ect.

RF-3005D/3005PRO is a mechanical meter with automatic range switching of A/mA, and the voltage and current are continuously adjustable within the standard value. lt has high precision, high reliability, and a complete overload protection circuit, which is idea for the industry.

Functions:

1. Voltage regulation: Twist directly the “V" knob regulates the voltage output. Press the “V" knob sequentially, and the corresponding adjustment voltage level indicator light flashes. Select the voltage you want to adjust and twist the “V" knob to quickly get the voltage you want to set.
2. Current regulation: Twist directly “A” knob regulates the current output. Press the "A" knob sequentially, and the corresponding adjustment current level indicator light flashes. Select the current level you want to adjust and twist the “A" knob to quickly get the current value you want to set.
3. Unlock/Lock function: Long press the “V" knob, wait for the lock indicator to be on, enter the locked state, at this time except the power switch button, all buttons and knobs are in a failed state; Long press the “V" knob to wait for the lock indicator to go off and unlock the state; All keys and knobs return to normal function.
4. Numeric Storage Keys Storage: Long press any one of the four storage keys, press the Go button to trigger a short “drop", do not let go will make a long “drop”, you can simultaneously store voltage, current and single inch current / continuous overcurrent / constant current settings. Recall it: Press the storage key briefly (let go immediately when you hear “drop"), you can call up the value stored by the last button, which is convenient and fast.
5. Fixed USB Output: This USB interface, fixed 5V2A output. It can power mobile phones or other 5V devices.
6. Continuous Overcurrent Protection: Press the continuous overcurrent protection button once (less than 1 second, and hear the prompt “drop” for a short sound), the continuous overcurrent protection light indicator lights up long to enter the continuous overcurrent protection state. This function is the most commonly used operating protection mode, and it can automatically return to the power supply state after overcurrent protection.
7. Single Overcurrent Protection: Press the single-shot overcurrent protection button once (less than 1 second, you can send it when you hear the prompt tone), and the single-time overcurrent protection indicator will enter the single-time overcurrent protection state when it is lit up for a long time. This feature is suitable for faulty circuits that cannot withstand multiple current surges. After a single overcurrent protection, the indicator flashes, displays the overcurrent value and flashes the power supply no output until the single overcurrent protection button is pressed again, and the function is restarted.
8. Constant Voltage Mode: Press the constant current and constant voltage mode key once (less than 1 second, you can send it when you hear the prompt Tone), and the constant current indicator will be solid to enter the single overcurrent protection state. At this time, except for the current mA/A, switching key, constant voltage constant current switching key, and voltage and current knob, other buttons are in a failure state, and this function is suitable for fault circuits that cannot withstand multiple current surges.
9. Output Press: Once to control power output.
   
10. Fixed Voltage Switching Function: You can switch the voltage values of 5V, 8.4V, 15V in daily work, and press this button once to switch to the next value (Switch only between 5V, 8.4V, and 15V values).

Safety Guides:

1. The cooling fan usually does not work; It starts automatically when the temperature reaches a fixeotemperature.
2. Do not block and isolate the air inlet and fan vents of the machine.
3. Avoid serious collisions or incorrect usage that can cause damage to the machine.
4. Keep the machine away from static electricity.
5. Non-professionals are prohibited from disassembling the machine.
6. AC input AC input voltage (Optional): 220V/50Hz, 110V/60Hz.
7. Connect the protective ground wire to the earth to avoid electric shock.
8. Fuse model corresponding to the fuse model: 220V/5A; 110V/ 10A.
9. Make sure you are using the correct fuse model before booting up.
10. To prevent fire, replace a fuse that meets the model and rating.
11. Do not connect the power cord before replacing the fuse to avoid electric shock.
12. Determine the cause of the blown fuse before replacing it.
