FEATURES & SPECIFICATIONS
DPS-305CF 30V 5A DC Digital Control Laboratory Adjustable Power Supply for Laptop Repair
DPS series digital input adjustable DC power supply is designed for laboratory, school, production lines and electronic repair designed for use. Voltage stability is high, small ripple factor, has improved the short circuit protection and overcurrent protection.
Due to the voltage value is a digital keyboard input, shorten the voltage setting time, completely overcome the traditional potentiometer adjustment poor contact caused by voltage instability phenomenon. The internal power supply containing electronic switch, can conveniently open the output load.
DPS – 305 CF : Five digit current display measuring accuracy : 00000-0.0450A, ±0.0001A
1, rated working conditions and dimensions
2, regulated state parameters
3, a constant current state parameters
4, current and voltage display accuracy
5, storage capacity
6, a voltage step range
Using notes :
1. the initial state power :
Power every time when energized, the first display888-888digital tube display models, and then, on the display a setting voltage and current values, and finally into the working state and output.
2. the value of the input voltage
A step input
Voltage input data is greater than 300and greater than 30V, instruments do not accept input, return not set before the voltage value. When the keyboard input data do not meet the requirements or input the wrong data, need to be removed to input new data in time, press the V key, so just input voltage data delete disappeared, can enter again. If this time to withdraw from the voltage setting state, only need to press the ENT key is returned ( and to exit the voltage input must press the V button, press ENT key to exit in return ).
Voltage display window a bit word flashing, then power waiting for input the data bits.
3. the value of the input current
Input current value is automatically transferred to the state apparatus constant current constant current value, when the load current is equal to and greater than the constant current value, the power from the voltage state into the automatic constant current state, current limitations in the set value to output, not cut load.
Column : the need for1.38A output current
Voltage input data is greater than500 and greater than or equal to 0.00A5A, instruments do not accept input, return not set the current value before.
In the time of pressing the I key, the input data is removed away, can enter again. If this time to exit the current settings, only need to press the ENT key is returned ( and to exit the current input mode must press the I button, press ENT button to exit in return ).
4. constant current and voltage characteristics
When the output current reaches a predetermined input constant flow and constant value, automatically from the constant voltage state into the constant current state, but along with the load current is lower than the set value, automatically from the constant current constant voltage state returned to the state. In the front panel of the indicating lamp V lights in a state of constant pressure, the front panel of the indicating lamp is bright in the I constant current state.
Column : for battery charging /12V DC power, the power output is set to 13.8V, the constant current value is set to1A, while the power supply output access storage battery,1A battery constant current charging, when the charging is finished, do not need constant current 1A charge, while the power supply for battery voltage13.8V trickle supplement.
5. power two current protection state operation
Power electricity per will automatically default to constant current CC protection status, current setting value is constant current protection current value.
OCP overcurrent automatic cut-off state of access methods :
First press the4keys do not loosen state, press I button, CC indicator lights up, enter the OCP overcurrent automatic cut-off state, and the state in the OCP, CV lights and CC lights is bright at the same time, before the input or preservation of the constant current value is automatically converted to COP automatically stops the output current value.
When the load current value equal to or greater than the OCP flow value, it will automatically stop output power, current and voltage display for 000-000, OUT lights at the same time out. Need to output voltage, simply press the OUT button, OUT lights, power supply is automatically the output voltage value.
Special note : when power is shut down after a reboot, OCP will automatically disappear, enter the CC constant current state.
6. keyboard password lock (303 / 305CM )
In a separate press ENT three banknote, V / ENT indicator light will flash, waiting to enter the password, the power to stop the output, if press the 258button three, ENT or V / ENT instructions exhibit of lanterns to slow blink, explain the password has been entered correctly, at the same time the output voltage. Such a state of V I 0. The key is lost, cannot change the voltage / current / storage / call / MA data. Password lift : repeat the above process after the first, on the restoration of V I 0key functions.
This code is available only to authorized users.
If you press the ENT three banknote, ENT lights flash quickly for several seconds, no password or password is not correct, then the apparatus automatically returned to the prior state.
7. The output switching function
When the instrument is OUT indicator light, press the OUT key, while the power supply stop output. When the instrument is OUT indicating lamp is extinguished, press the OUT key and in the release, while the power supply is output, while OUT indicator light.
8. Storage / call (303 / 305CM )
A storage :
To set up the required storage V, I value, in a separate press. ( decimal ) button for 3 seconds and then, V / ENT lamp flashes slowly, power into the storage state, then slow flashing5 seconds, if press0 to9number keys, then current, voltage data is stored in the keys ( such as1, depositing a1keys ). At the same time, V / ENT lights flashing, and enters into the working state.
If the slow flashing 5seconds without press 0to 9keys, then from the stored state and back to work.
B quick call :
Separate quick click. ( decimal ) key, V / ENT lamp flashes, power into the out of state, in the rapid flashing3 seconds, if press0 to9 number keys, power supply is automatically removed existed before0 to9keys in the current and voltage data, and display and output.
If the flash quickly for 3seconds without press 0to 9keys, then from out of state and back to work.
9. The current A / mA conversion
Initial electrifying current A or constant current A display, maximum output current of 3A or5A, when the separate press 0keys, 3 seconds later, the mA indicator light, current decimal point out, power into the output state, the current display or a constant current value is Ma units, the maximum output current of 0.5A.
If the power needed to return to the A state, Shun again separate press 0keys, 3 seconds later, the mA indicator is extinguished, it returns a A state.
At this point you can measure the maximum current of 500mA, a constant current is500 ma.
10. The increase of cooling fan
This machine is no fan design, support for the full power output, for24 hours or longer continuous full power output, can be added to reduce the temperature in the machine fan.
Method : the machine installation in power supply board reserved fan interface CJ11(Vcc is positive) and a fan fixing hole, a user only needs to add model 802524V voltage for DC fan.
1. The input voltage selection : the input AC voltage should be 220V + 10%50Hz.
2. The ground : three core power line to the protective earth terminal earth must be reliable access security, to ensure that users and peripheral equipment safety.
3. Insurance tube replacement : when the power supply after pressing the power switch, panel lights and digital tube are all bright, there may be
Insurance tube burn, if confirmation is insurance tube burn, will have to find the insurance tube burn causes and elimination, substitution of the same specifications
Insurance tube. Remember, replacement of the fuse tube must pull the power plug from the socket removed, can be replaced.
4. Placing : to ensure the power of life, being used for a long time, please keep power placed in well-ventilated environment make (23 degrees C. do not put in the environment temperature is higher than 40 DEG C place, radiator is located on the instrument’s rear, should leave enough space
, to facilitate heat dissipation. Not a long time, should be the power supply plug.
5. Abnormal operation : the power supply mode of operation and non operation will not cause the power damage, but has the potential to damage the load ( when the output voltage exceeds the load voltage ).
