TH6700系列是一款单路输出、宽范围可编程开关直流电源，有输出功率为360W、720W以及1080W的三种机型。用户可以实现主从串联2台或者主从并联3台TH6700电源，满足更高的输出电压和输出电流需求。
TH6700系列具有可调斜率功能，用户可以设置输出电压、电流的上升、下降时间，避免开关瞬间的浪涌电流破坏器件。
TH6700系列的恒压/恒流优先选择模式能够很好的保护被测件。传统电源在输出开启时通常处于CV模式，这会瞬间给容性负载带来较大的浪涌电流。TH6700系列在输出开启瞬间，能优先运行在CC模式，避免突发的尖峰电流，保护器件。
TH6700系列的可编程内阻功能可应用于仿真电池的输出。例如，TH6700可以设置模拟电池内阻的电阻值，从而使输出电压下跌。
TH6700系列提供OVP、OCP和OTP保护。输出电压或电流一旦超过预先设定的值，输出立即关闭；机器内部的温度一旦超过一定的温度，输出也会立即关闭。
TH6700系列后面板可以接成两端量测或四端量测。接成四端量测时具有远端补偿功能，可补偿电源到待测件上的压降。
Functional Features
A. 可调斜率功能
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. 可编程内部电阻 - 仿真电池输出
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. 数据保存 – 记录被测件运行数据
用于记录电流、电压、时间等数据，打开记录后以1 次/s的速率开始记录，最大5000 次。
接上sense端则记录被测件两端实际电压、电流值；
不接sense端则记录TH6700输出的电压、电流值。
结束后，仪器数据将以CSV后缀名保存至 U 盘CSV 文件夹下。
D. 恒压（CV）/恒流(CC)优先选择模式 – 保护被测件
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.
恒流优先模式是指在输出开启瞬间，优先运行在CC模式,可以:
1. 避免突发的尖峰电流，保护器件免遭浪涌电流损坏。
2. 输出电流无过冲，用来测试恒流工作特性的待测物
