TH6723A 可编程开关直流电源

The TH6700A series is a single output, wide-range programmable switching DC power supply available in 360W, 720W and 1080W outputs. Users can realize master-slave series connection of two units or master-slave parallel connection of three units of the same type of power supply to meet higher output voltage and output current requirements.

TH6700A series has an adjustable slope function, which allows users to set the rise and fall time of the output voltage and current to avoid damaging the device by the surge current during the switching moment.

The constant voltage/constant current prioritization mode of TH6700A series can protect the DUT well. Conventional power supplies are usually in CV mode when the output is turned on, which will instantly bring large inrush current to capacitive loads. TH6700A series can prioritize CC mode when the output is turned on, avoiding sudden spike current and protecting the device.

The programmable internal resistance function of the TH6700A series can be applied to simulate the output of a battery. For example, the TH6700A can set the resistor value that simulates the internal resistance of the battery so that the output voltage drops.

The TH6700A series provides OVP, OCP and OTP protection. Once the output voltage or current exceeds the pre-set value, the output will shut down immediately; once the temperature inside the machine exceeds a certain temperature, the output will also shut down immediately.

The rear panel of the TH6700 series can be connected for two-end or four-end measurement. When connected for four-terminal measurement, it has a remote compensation function that compensates for the voltage drop from the power supply to the part to be measured.

The TH6700 series programmable switching DC power supplies include the following types:

Functional Features

A. Adjustable slope function

Control the output by setting the voltage or current rise/fall time to obtain the voltage/current conversion rate

For example, if you set the output voltage to 20V and the voltage conversion rate to 5V/s, the rise time is 4s;

A voltage conversion rate of 10V/s results in a rise time of 2s;

A voltage conversion rate of 20V/s results in a rise time of 1s;

A voltage conversion rate of 40V/s results in a rise time of 0.5s.

B. Programmable Internal Resistors - Emulates Battery Outputs

Batteries generally have internal resistors, and when powered by batteries, the output voltage drops due to voltage dividing by the battery's internal resistors.

Calculation formula:

Use the TH6700 to set the analog internal resistance value so that the output voltage falls, simulating the true output of the battery.

C. Constant Voltage (CV)/Constant Current (CC) Priority Selection Mode - Protects DUTs

Conventional power supplies are usually in CV mode when the output is turned on, which can instantly introduce a large inrush current to capacitive loads.

Constant Voltage Priority Mode for obtaining a faster rate of voltage creep when the output is turned on in order to target test scenarios that require high voltage speeds.

Constant Current Priority Mode means that at the moment the output is turned on, it operates in CC mode with priority, which can avoid sudden spike current and protect the device from being damaged by inrush current. The output current has no overshoot and is used to test the constant current operating characteristics of the object to be tested.
