FTL series programmable DC power supply

FTL is a high performance, versatile, medium and small power, series programmable DC power supply. The product is stable and mature, and has comprehensive protection functions such as overload, polarity reversal, overvoltage, overcurrent, over temperature, etc., which can keep the power and load in the unstable environment. With an adjustment ratio of less than 0.01% and chopping and noise of less than 1mVrms, FTL automatically selects internal continuous or dynamic loads for applications such as current surges. The FTL series is suitable for both high-index laboratory use and high-performance test systems.

Functions & Advantages

Remote sensing function

When the load consumes a large current, a voltage drop is generated on the connection line from the power supply to the load terminal, and the remote sensing can automatically compensate the voltage drop of the load line. The wiring diagram of the remote sensing function power supply measurement is as follows: 

 

 

 

3 BUS Trigger for the communication interface.

Trigger function

FTL supports 4 trigger modes. You can use the numeric keys or knob to select the trigger source:

0 EXT: Trigger for an external button.

1 PULSE is the rear panel TTL trigger.

2 IMM: Trigger for the command. 

Battery curve charging function

FTL can charge the battery curve, as shown below, which can effectively protect the battery.
