The SPS‑A Series is the new generation of switching DC power supplies, upgraded from the original SPS Series to offer a more intuitive interface, higher control accuracy, and enhanced protection features. The lineup includes five models—SPS‑1230A, 1820A, 2415A, 3610A, and 606A—each equipped with an encoder‑type digital knob for faster and finer voltage/current adjustments. A 2.4‑inch TFT‑LCD color display provides clear visibility, allowing users to easily monitor output status in any test environment.

To improve measurement accuracy, the SPS‑A Series supports Remote Sensing with 2‑wire/4‑wire switching, effectively compensating for line voltage drop and ensuring precise voltage at the load. Built‑in OVP, OCP, and OTP protection mechanisms respond immediately to abnormal conditions, safeguarding both the DUT and the instrument.

For operational convenience, the series offers three memory and recall presets plus one power‑on default setting, enabling quick recall of frequently used configurations. With a setting resolution of 10 mV / 10 mA and a readback resolution reaching 10 mV / 1 mA, the SPS‑A Series is ideal for applications requiring precise control. A front‑panel lock function prevents accidental operation, making it suitable for production lines and long‑duration testing.

The SPS‑A Series also supports the GRA‑441‑J/E rack‑mount kit for easy integration into automated test systems. The dedicated output On/Off key ensures safer operation by allowing users to complete all settings before enabling the output.

Overall, the SPS‑A Series delivers higher precision, a more intuitive user experience, and comprehensive protection, making it an excellent choice for R&D, education, and production testing environments.
