What it is
A new generation of 360 W single-channel switching DC power supplies in five models, from 12 V/30 A to 60 V/6 A, with an encoder digital knob and a 2.4-inch TFT LCD color display.
Remote sensing with 2-wire/4-wire switching compensates for line voltage drop, and built-in OVP, OCP, and OTP protect against abnormal conditions. Setting resolution reaches 10 mV / 10 mA, with readback down to 1 mV / 1 mA.

What does the SPS-A Series do?
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, the SPS-1230A, SPS-1820A, SPS-2415A, SPS-3610A, and SPS-606A, each equipped with an encoder-type digital knob for faster and finer voltage and 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 1 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.
Key Features
- Replaces the original SPS-series products
- Equipped with an encoder switch digital control knob
- Remote sensing function with 2-wire/4-wire switching
- Provides OVP, OCP, and OTP protection mechanisms
- Three preset memory/recall settings
- Setting resolution: 10 mV / 10 mA; readback resolution: 10 mV / 1 mA
- Output on/off control
- Panel lock function
- Control I/O functionality
- Compatible with GRA-441-J/E rack mount kits

Why engineers pick it
- Low noise for a switching supply. CV ripple and noise is ≤5 mVrms (5 Hz … 1 MHz), with line and load regulation of ≤5 mV.
- Accurate at the DUT. Remote sensing compensates up to 0.5 V of line drop, switchable between 2-wire and 4-wire.
- Fast, readable setup. The encoder knob and 2.4-inch color display set voltage and current quickly, with readback resolution reaching 1 mV / 1 mA.
- Ready for production. Panel lock, output on/off key, status signal outputs (output on/off, CV, CC, ALM, PWR ON), and rack mount kits suit production lines and long-term operation.
Which SPS-A model do I need?
| Model | Voltage | Current | Power |
| SPS-1230A | 0 … 12 V | 0 … 30 A | 360 W |
| SPS-1820A | 0 … 18 V | 0 … 20 A | 360 W |
| SPS-2415A | 0 … 24 V | 0 … 15 A | 360 W |
| SPS-3610A | 0 … 36 V | 0 … 10 A | 360 W |
| SPS-606A | 0 … 60 V | 0 … 6 A | 360 W |
Each model comes with either a standard type jack terminal or a European type jack terminal. The included test leads differ by terminal type.
When is the SPS-A the wrong choice?
- More than one output. The SPS-A is a single-channel supply.
- Power above 360 W. Every model is rated 360 W.
- Series or parallel operation. The SPS-A Series does not provide series or parallel connection between units.
- Hot environments. Operating temperature is 32 … 104 °F (0 … 40 °C), with relative humidity at or below 80%.
