Sequence control is a method used to execute operations according to a predetermined order or logic. In the context of power supplies, it automates output patterns by changing voltage and current settings over time. This involves Step changes (discrete increments) or smooth Ramp transitions. Unlike standard operation where a user manually sets a constant output, sequence control allows the power supply to autonomously follow a programmed profile.
Sequence control is essential for reproducing dynamic power environments. While a standard power supply maintains a fixed output, a sequence-enabled unit can simulate fluctuating conditions, such as the voltage drop during engine ignition or the charge-discharge cycles of a battery. This capability allows for complex testing without the need for continuous manual adjustment or external computer control.
In power supply applications, sequence control is a powerful feature that allows users to create and automate complex output patterns. By programming a series of voltage and current settings over time, users can simulate real-world power conditions, automate repetitive tests, and precisely manage power delivery to a device under test (DUT).
Matsusada Precision offers a wide range of programmable DC power supplies, high-voltage power supplies, and electronic loads featuring built-in sequence functions. Users can program complex patterns--combining steps, ramps, and loops--directly into the unit. This stand-alone capability eliminates the need for a dedicated PC or external controller during operation, simplifying test setups and ensuring high-speed execution unaffected by communication latency.
These features are ideal for R&D and production lines requiring precise automation, such as automotive component testing, battery simulation, and semiconductor evaluation. Key models include:
