Programmable DC Power Supply Tonghui TH6741 (800V-1.32A)

Description Tonghui TH6741 

TH6700 series is a single channel output, wide range programmable switch mode DC power supply, with three output powers of 360W, 720W, and 1080W. Users are able to realize 2 master-slave in series or 3 master-slave in parallel connection, to achieve the requirements of higher voltage and higher current output.

TH6700 series is designed with adjustable slope function that allows users to set the rise time and fall time of current and voltage output. When testing lighting devices and large capacitors, inrush current will be generated as soon as the output is turned on, which severely shortens the lifetime of the tested parts. In this case, the slope function ensures the voltage transmission is smooth and slow at the switching moment which prevents the tested parts from being damaged.

TH6700 series CV/CC priority mode protects the tested parts well. The traditional power supply in CV mode will instantly bring a large surge current to the capacitive load while turning on the output. TH6700 series power supply can run in CC mode at the start of output, which avoids sudden peak current and protects the device from being damaged by surge current.

TH6700 series can simulate battery output with its programmable internal resistor. For instance, a battery supplies power to a device, the applied voltage drops as it passes through the battery's internal resistance. With TH6700 series power supply, the internal resistance can be simulated by setting values, thus causing the output voltage to drop.

TH6700 series provides OVP, OCP, and OTP protection function. Once the output voltage or current exceeds the preset value, the output will be immediately shut down. Once the temperature inside the machine exceeds a certain temperature, the output will be shut down as well.

TH6700 series can be connected to 2 or 4-terminal measurement from the rear panel. The 4-terminal measurement has the remote compensation function, which compensates the pressure drop from the power supply to the parts to be tested.

TH6700 series is equipped with abundant interfaces, such as USB HOST, USB DEVICE, LAN, RS232, and analog control interface. The CV/CC mode controlled by external voltage and external resistance is implemented through analog control interface.  In series or in parallel operation is realized through analog control interface. It also supports external voltage or external resistance to control the instrument output.
