The Okuma DC-S3A is a Japanese-manufactured DC power supply product, designed for safety and automation applications within a motion control system. Paired with the manufacturer's three-axis and six-axis servo drive, this power supply communicates via a converter link and can connect simultaneously to multiple servo drives. Notable features include a green LED light indicator and an external switch. A major function of the device is to convert fluctuating alternating current into stable direct current voltage, drawing power primarily from AC mains. Fitted with large capacitors, the DC-S3A smoothens electrical noise and stores energy. A built-in transformer adjusts voltage amplitude, offering high-frequency operations. The power supply weighs 13.4 kilos and if an HV alarm in the axis drive happens intermittently, the power supply may need replacement. The unit also includes regulators to maintain output voltage.
