The influence of Power Sequence

All applications in electronics or electrical industry need the power supply,

especially for power sequence management due to many chipset or sub-system

inside the circuitry are operated by different power sequence. A wrong power

sequence management will cause a serious problem even have a damage on our

own system, so Rigol DP832A DC Programmable Power Supply can solve these

definitely in advance.

Power Sequence Management

Applications of Waveform Regeneration

Application:

1. Power IC Simulation

2. Embedded System Power Management

3. Large Scale Circuitry Power Management

4. Mid-Range Industrial Control Power Management ( < 195W )

5. Electrical-Mechanics Power Application ( < 195W )

Power Sequence is important in Embedded System
