DPS8005 Digital control power supply constant voltage current Step-down power supply module Voltmeter Ammeter buck converter 80V 5A

General Information:

The programmable Power supply offers constant Current and constant Voltage and combines both analog and digital technology in an integrated and advanced design.

The fully adjustable output ranges from 0-80.00V in 0.01V (10mV) steps and the fully adjustable Current Limited output ranges from 0-5.100A in 0.001A (1mA) steps.

The unit offers non-volatile power off parameter storage and 10 programmable preset memory Data Groups with a quick recall function for groups 1 and 2.

The digital control interface offers a comprehensive feature set not available on analog only power supplies. The keypad and rotary control offer simple input and selection of all required settings whilst the full colour LCD offers detailed display of the extensive but easily read information relating to system operation and performance. Items that can be displayed include a precision voltmeter and ammeter, preset Voltage, output Voltage, preset Current Limit, output Current, output Power and Data Group selection parameters and menus. Notification icons and text include indications such as output enabled or disabled, Constant Current or Constant Voltage mode of operation, abnormal condition warning, keypad locked or unlocked state and the Data Group in use. The Data Setting interface allows full adjustment of Over-Current, Over-Voltage and Over-Power protection values, Data Group settings and LCD brightness. The unit offers a technologically advanced design presented in a very compact size that is both visually appealing and easy to operate.

Operating instructions

When the unit is first powered on the Welcome screen is displayed followed shortly by the Main Interface screen. On the Main Interface screen the selected (SET) Voltage and Current Limit values are displayed on the top of the screen. When the output is enabled the actual real output Voltage, Current and Power are displayed in the large font. The actual input Voltage is displayed at the bottom of the screen. On the right side of the screen are icons and prompts indicating system status. These are: keypad lock state icon, abnormal output status icon, Constant Voltage / Constant Current icon, preset Data Group memory number (when selected) and output enabled / disabled icon.

Set the output Voltage and output Current Limit via the Main Interface.

Press V/↑key to enter the Voltage setting mode. The Voltage setting numeric value will be highlighted by the cursor. Press the rotary control to place the cursor at the required character of the numerical value you wish to change. Further presses of the rotary control will cycle through the characters available. Turning the rotary control clockwise increases the value and anticlockwise decreases the value. Press V/↑again to exit. Alternatively, after 30 seconds of inactivity the setting mode will exit automatically. Press A/↓to set the output Current Limit using the same procedure.

Set data values via the Data Setting Interface

Entering the Data Setting Interface

On the main interface press the SET key to enter the Data Setting Interface.

Set Voltage and Current Limit values

In the Data Setting Interface press V/↑or A/↓to step up or down through the menu options to select U-SET (Voltage) or I-SET (Current Limit), and then set the output Voltage and output Current Limit in the same way as used in the main interface. Press the SET key to return to the menu options and press the SET key again to exit.

Set the Protection Values.

Press V/↑or A/↓to step up or down through the menu options to select S-OVP (Over-Voltage Protection), S-OCP (Over-Current Protection) or S-OPP (Over-Power Protection) limits. Press the rotary control to place the cursor at the required character of the numerical value you wish to change. Set the value required in the same way as used in the main interface. Press the SET key to return to the menu options and press the SET key again to exit.

When any of the protection value limits are reached the output will be automatically disabled.

These are the global system protection limits and should not be confused with preset Voltage and Current.

Adjust the Screen Brightness

Press V/↑or A/↓to step up or down through the menu options to select B-LED, and then press the rotary control to highlight the brightness setting value. Turn the rotary control to adjust the brightness from 0 to 5 where 0 is the darkest and 5 is the brightest. Press the SET key to return to the menu options and press the SET key again to exit.

M0-M9 Data Groups

M0 Data Group

The M0 Data Group is a special case. It is the power default Data Group. It should be noted that any time an alternative Data Group is selected or any changes made to the existing settings then M0 will be immediately overwritten with the newly selected data. In effect, M0 is always a real-time duplicate of the currently selected Data Group and data values. It is also the data-set that will be saved at power off and recalled at next power on. This happens automatically and transparently with no input necessary from the user.

Shortcut keys to select and recall M1 or M2 Data Group

From the main interface, press and hold V/↑or A/↓for more than 3 seconds to quickly recall the M1 or M2 Data Group. The corresponding Data Group number will displayed on the right of the screen. The M1 and M2 Data Groups are ideal choices for commonly used settings due to the quick recall function.

Select and recall any specific Data Group.

From the main interface, press and hold the SET key more than 3 seconds, M0 will be displayed on the right side of the screen. Turning the rotary control allows selection of the required Data Group (M1 to M9). To activate the selected Data Group press the SET key.
