The adjustable output makes the SPS305C suitable for powering electronic components and modules during testing, monitoring current consumption, and verifying electrical operating conditions during electronics development and troubleshooting.

OCP Protection for Electronic Component Testing:

The SPS305C provides OCP (Over Current Protection) to help protect the power supply and connected equipment when excessive current conditions occur.

During electronic component testing, incorrect connections, abnormal loads, shorted components, or unsuitable operating conditions may cause excessive current. The OCP function provides additional protection under these conditions.

This is particularly useful for:

• Electronic component testing

• Prototype circuit testing

The OCP function helps provide additional protection when engineers are testing newly developed or potentially faulty electronic components and circuits.

Battery Charging Function for Electronics Testing:

In addition to adjustable DC output, the SPS305C includes a dedicated battery charging function for compatible rechargeable batteries.

The battery charging function provides:

• Battery charging mode

• Charging status indication

• Accumulated charged amount display in Ah

• Reverse polarity protection

• Overcharge protection

• Automatic output shutdown after the battery is fully charged

This function can also be useful when testing battery-powered electronic components, portable electronic modules, battery charging circuits, and other electronic devices that incorporate rechargeable batteries.

Low-Ripple Adjustable DC Output:

The SPS305C provides low-ripple DC output for electronic component, module, and circuit testing.

Its voltage ripple is specified at:

• ≤60mVp-p

The current ripple is:

• ≤10mArms

Low-ripple output is useful when powering electronic components and modules during testing, particularly when stable DC power is required for consistent test conditions.

Electronic Component Testing Protection

OCP — Over Current Protection

The SPS305C provides an OCP (Over Current Protection) function to help protect the power supply and connected equipment when excessive current conditions occur.

During electronic component testing, abnormal loads, shorted components, or incorrect connections may result in excessive current. OCP helps provide additional protection during these conditions.

Reverse Polarity Protection

The SPS305C provides reverse polarity protection during its battery charging function.

Incorrect battery connection can cause abnormal charging conditions. The battery charging function is designed to identify incorrect connection conditions and provide protection against damage caused by reverse polarity.

This function is particularly useful for:

• Rechargeable battery charging

• Battery-powered electronic device testing

• Battery charging circuit testing

• Charging process verification

• Electronics testing workstations

The battery charging indicator provides a visual indication of connection and charging status.

Overcharge Protection

The dedicated battery charging function provides overcharge protection.

When the battery reaches full charge, the SPS305C can automatically turn off the output to help prevent continued charging after the battery reaches its charging limit.

This provides additional convenience when testing battery-powered electronic components, modules, or charging circuits.

Output Switch

The independent OUTPUT control allows users to set voltage and current parameters before applying output power to the connected electronic device.

This helps reduce the possibility of applying an unintended output condition when connecting an electronic component, module, circuit board, or other device during testing.

✦ Real-Time Electrical Parameter Display

The SPS305C provides a digital display for monitoring important electrical parameters during operation.

Users can observe:

• Voltage

• Current

• Power

• Ah

• Charging status

• Output status

During electronic component testing, the real-time display allows engineers to observe changes in current and power when a component or module is powered, helping them monitor the electrical behavior of the device under test.

The Ah display is particularly useful when the tested electronic system includes rechargeable batteries, allowing users to observe the accumulated amount of charge delivered during a charging session.

✦ Precise Encoder Adjustment

The SPS305C uses encoder controls for voltage and current adjustment.

The encoder adjustment system allows users to conveniently set the required voltage and current parameters during component testing, circuit debugging, module evaluation, and electronics development.

With:

• 10mV voltage setting resolution

• 1mA current setting resolution

users can make relatively fine adjustments to the output parameters according to the requirements of the connected electronic component or device.
