Providing a reliable DC input source for power electronics development and validation.

✦ Real-Time Voltage & Current Curve Display for Converter Evaluation

The integrated 2.8-inch TFT color LCD provides real-time voltage and current curve visualization, helping engineers observe changes in power behavior during DC-DC converter testing.

The curve display can help engineers monitor:

• Startup current changes

• Input current fluctuations

• Voltage stabilization behavior

• Load-related current changes

• Abnormal current variations

• Power behavior during different test stages

By observing voltage and current trends directly on the display, engineers can identify abnormal behavior more quickly and improve debugging efficiency.

This is particularly useful when evaluating:

• Buck converters

• Boost converters

• Buck-boost converters

• DC-DC power modules

• Voltage regulator circuits

✦ 10μA Microcurrent Measurement for Low-Power Converter Testing

Many modern DC-DC converters are designed for embedded and battery-powered electronics where low standby and quiescent current are important.

The SPPS-K3010 supports high-resolution current measurement with automatic current unit conversion and a 10μA readback resolution at the low-current range.

Engineers can use it to observe:

• Standby current

• Low-load current

• Sleep-mode power consumption

• Converter startup current

• Light-load operating behavior

• Abnormal current consumption

The 5-digit high-resolution display makes small changes in voltage and current easier to observe during converter evaluation.

This helps engineers identify unnecessary power consumption and optimize power management designs.

✦ 4 Memory Presets for Repeatable Converter Testing

DC-DC converter evaluation often requires testing the same device under multiple input conditions.

The SPPS-K3010 provides 4 groups of programmable memory presets, allowing engineers to save frequently used voltage and current settings.

Example test configurations:

M1: Low-input-voltage test
M2: Nominal-input-voltage test
M3: High-input-voltage test
M4: Low-load or standby test

With quick parameter recall, engineers can switch between different test conditions without repeatedly adjusting the power supply manually.

This improves testing efficiency and helps maintain more consistent test conditions during development.

✦ Precise Output Control for DC-DC Converter Protection

During converter development, incorrect input voltage, excessive current, or wiring errors may damage prototypes and evaluation boards.

The SPPS-K3010 provides multiple protection functions:

OVP — Over Voltage Protection

Helps prevent excessive output voltage from being applied to sensitive DC-DC converter input circuits.

OCP — Over Current Protection

Helps limit abnormal current conditions during converter startup, testing, or fault conditions.

SCP — Short Circuit Protection

Provides protection for the power supply and connected circuits in the event of accidental short circuits.

Panel Lock Function

Helps prevent unintended voltage or current adjustments during extended testing.

These protection features provide an additional layer of safety when working with prototype converter boards and power electronics.

✦ Standby & Output Control for Power Consumption Evaluation

For DC-DC converters used in battery-powered and embedded systems, standby and low-power operation are important evaluation factors.

The SPPS-K3010 provides clear operating status information and an output enable switch, allowing engineers to configure voltage and current before activating the output.

This is useful for evaluating:

• Converter standby behavior

• Low-power operating conditions

• Startup current

• Power-on behavior

• Input power consumption

• Different converter operating states

The output can be enabled after the required parameters have been configured, helping reduce unexpected power application during testing.

✦ High-Resolution Adjustment for Power Electronics R&D

DC-DC converter testing often requires precise input voltage and current adjustment.

The SPPS-K3010 uses precision encoder adjustment for smooth voltage and current configuration.

Combined with:

• 1mV voltage resolution

• 1mA current setting resolution

• 10μA current readback resolution

• 5-digit high-resolution display

the power supply provides engineers with detailed control and measurement during converter development.

This is useful when comparing converter performance at different input conditions or investigating small changes in power consumption.
