The MP3 player uses the digital signal processor DSP (Digital Sign Processer) to complete the task of processing transmission and decoding of MP3 files. DSP rules the data transmission of the Walkman, device interface control, file decoding playback and other activities. DSP can perform a variety of processing tasks in a very short time, and this process consumes very little energy (this is also a significant feature of its suitability for portable players).
APM SP300VAC3000W is an economically programmable DC and AC output power supply to provide reliable voltage and simulation for general applications such as testing for commercial, power electronics, avionics, military and IEC regulation test applications. The AC power source has various communication interface and can be remote controlled by computer.
The AC source is capable of delivering up to 6 times of peak current compared to its maximum rated current that makes it ideal for inrush current test.
Some features as below:
- 5.6"large touch color screen
- AC+DC mixed or independent output mode
- Capable of setting output slope/phase angle
