Sequence control is a control method where operations are executed according to a predetermined order or logic. This can involve simple Step changes, where settings are adjusted in discrete increments, or smooth Ramp transitions over a specified time. It's a form of open-loop control, where the system follows a pre-programmed set of instructions without using sensor feedback to adjust its actions in real-time.

A common example is a washing machine. It performs a series of fixed operations--wash, rinse, and spin--in a predefined order. This is different from feedback control (or closed-loop control), like an air conditioner that uses a temperature sensor to continuously adjust its operation to maintain a set temperature.

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 equipped with a sophisticated built-in sequence function. This enables users to program and store complex sequences--combining steps, ramps, and pulses--directly in the unit's memory. This stand-alone capability eliminates the need for a dedicated PC or external controller, streamlining setup and improving test reliability.

This advanced sequence control is essential for cutting-edge R&D and production lines, including automotive component testing, battery charge/discharge simulation, and semiconductor manufacturing processes. Key models featuring this powerful sequence function include:
DC Power Supplies: R4K-36, R4KF-80, R4K-80, R4GT, PKTS, TB, RK, PVCE, PRKT, RKT, REK/REKJ, PRT/PRTM, PBR/PBRM
High-Voltage Power Supplies: EPR, HARS
