CUSTOM DC stabilized power supply DPS-3003 / DPS-3005C

A slim DC stabilized power supply that can supply stable power.

• It uses a switching regulation method, making it small, lightweight, and highly efficient.
• The output voltage can be continuously adjusted from 0V to each rated voltage.
• The output current can be continuously adjusted from 0A to each rated current, and each output is displayed digitally on the LED display.

Part names

Main unit

• ① Voltage display: Displays the output voltage with an LED.
• ② Current display: Displays the output current with an LED.
• ③ CV (constant voltage) lamp: The green LED lights up when CV (constant voltage) is operating.
• ④ Power switch: This is the switch to turn the power of the main unit on and off.
• ⑤ CC (constant current) lamp: The red LED lights up when CC (constant current) is operating.
• ⑥ - (minus) output terminal: This is the terminal to connect the (-) side of the output cord.
• ⑦ GND terminal: This terminal is connected to the main chassis.
• ⑧ + (plus) output terminal: This is the terminal to connect the (+) side of the output cord.
