Topkko Dual-Channel DC Power Supply 0-30V 0-10A ×2 (300W ×2)

Dual Independent Channels with 3 Switching Modes

Independent Mode (INDEP): CH1 and CH2 operate completely independently without interference, allowing simultaneous output of different voltages and currents.

Series Mode (SER): One-touch internal series connection doubles the voltage output (e.g., 30V + 30V = 60V) without requiring external jumper wires.

Parallel Mode (PAR): One-touch internal parallel connection doubles the current output (e.g., 5A + 5A = 10A), significantly boosting total power capability.

Dual High-Brightness 4-Digit LED Displays

Simultaneous Dual Display: Large LED screens clearly display Voltage (V), Current (A), and Power (W) for both CH1 and CH2 in real time.

C.V / C.C Indicators: Both channels feature independent Constant Voltage (C.V) and Constant Current (C.C) status LED indicators for intuitive monitoring.

Convenient Panel Control & Expansion

Independent Adjustment Knobs: Dedicated VOLTAGE and CURRENT encoder knobs for both CH1 and CH2 ensure precise parameter tuning for each channel.

Auxiliary USB Port: Features a front-panel 5V/2A USB output port to power mobile devices, development boards, or portable testing tools.

Professional Output Terminals & Compact Design

6-Terminal Output Architecture: The front panel provides clear and secure binding posts for CH1 (+/-), CH2 (+/-), and dedicated SER/PAR (+/-) outputs.

•  Dual Independent Channels: Two separate channels allow CH1 and CH2 to operate independently, providing different voltage and current outputs simultaneously.
•  3 Selectable Operating Modes: Supports Independent (INDEP), Series (SER), and Parallel (PAR) modes for flexible power output configuration.
•  Series Mode for Higher Voltage: Internal series connection combines CH1 and CH2 outputs to increase voltage, such as 30V + 30V = 60V, without external jumper wires.
•  Parallel Mode for Higher Current: Internal parallel connection combines the current capacity of both channels, such as 5A + 5A = 10A, for higher-current applications.
•  Dual 4-Digit LED Displays: High-brightness LED displays provide clear, real-time readings of Voltage (V), Current (A), and Power (W) for both channels.
•  C.V / C.C Status Indicators: Dedicated Constant Voltage (C.V) and Constant Current (C.C) indicators for each channel allow quick monitoring of the operating mode.
•  Independent Voltage & Current Adjustment: Separate VOLTAGE and CURRENT control knobs for CH1 and CH2 enable precise output adjustment.
• Built-In 5V / 2A USB Output: Convenient front-panel USB port provides 5V / 2A output for compatible devices, development boards, and portable testing equipment.
•  6-Terminal Output Configuration: Front-panel binding posts provide dedicated connections for CH1 (+/-), CH2 (+/-), and SER/PAR (+/-) outputs.
•  Flexible Professional Design: Suitable for electronics testing, circuit development, laboratory applications, component servicing, repair work, and DIY projects.
