Tonghui TH6711 DC power supply

Key Features

 Output Characteristics

• Wide Range and Constant Power Output: This series provides a broad range of voltage and current outputs while maintaining a constant power level. This feature is highly beneficial for applications that require different power supply conditions without sacrificing power stability.
• High Efficiency and Power Density: It is designed with high – efficiency components, ensuring that the power supply can convert electrical energy with minimal loss. The high power density allows for a more compact design, making it suitable for applications where space is limited.
• Programmable Internal Resistance: Specifically designed for battery output simulation, users can program the internal resistance of the power supply. Just like in a real – world battery scenario, when power is supplied, the voltage drops as it passes through the internal resistance. This feature enables accurate replication of battery – like behavior, which is useful for testing devices that are powered by batteries.

 Operational Modes

• Constant Current (CC) Priority Mode: In LED power supply applications, overshoot can be a major problem that may damage the LEDs. The CC priority mode of the TH6700 series helps prevent this overshoot by ensuring that the power supply starts in CC mode. This mode controls the current output to avoid sudden peaks, protecting the LEDs and other sensitive components.
• Master – Slave Series and Parallel Operation: Users can connect two power supplies in master – slave series or three in master – slave parallel. This flexibility allows for achieving higher voltage or higher current outputs, making it suitable for applications that demand more power than a single unit can provide.

 User – Friendly Interface

• 24 – bit 4.3 – inch Color LCD Display: The power supply is equipped with a high – resolution 24 – bit 4.3 – inch color LCD display. This display provides clear and detailed information about the power supply’s settings, output voltage, current, power, and other parameters.
• Numeric Keyboard and Knob Operation: A numeric keyboard allows for precise input of values, while the knob can be used for both coarse and fine adjustment of voltage and current. This dual – control method provides users with a convenient way to set the desired output parameters.
• Programmable Voltage or Current Rising Time: The adjustable slope function enables users to set the rise time and fall time of the voltage and current output. When testing lighting devices and large capacitors, inrush current can occur when the power supply is turned on, which may damage the tested components. By setting a slow rise time, the slope function ensures smooth voltage transmission, protecting the components from damage.
