The SPS305C provides 0–30V and 0–5A adjustable output, with a maximum output power of 150W, delivering controlled DC power for PCBs, electronic modules, sensors, components, and other compatible electronic devices.

As an adjustable bench power supply for electronics repair, the SPS305C allows technicians to set the required voltage and current before applying power to the device under test. This is useful when checking whether a circuit can operate normally under controlled DC input conditions.

The SPS305C supports:

• 0–30V adjustable output voltage

• 0–5A adjustable output current

• 150W maximum output power

• 10mV voltage setting resolution

• 1mA current setting resolution

• 10mV voltage readback resolution

• 1mA current readback resolution

The adjustable output makes the SPS305C suitable for powering electronic circuits during troubleshooting, testing current consumption, and verifying the operating condition of repaired or prototype devices.

Over Current Protection for Circuit Troubleshooting:

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

During electronics repair, incorrect wiring, shorted components, abnormal loads, or incorrect parameter settings may cause excessive current. The OCP function provides additional protection under these conditions.

This is particularly useful for:

• PCB troubleshooting

• Prototype circuit testing

The OCP function helps provide additional protection when technicians are diagnosing unknown or potentially faulty electronic circuits.

Battery Charging Function for Electronics Service:

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 makes the SPS305C useful when electronics repair involves rechargeable batteries or battery-powered devices. Technicians can monitor charging voltage, current, power, and accumulated Ah during battery-related service and testing.

Low-Ripple DC Output:

The SPS305C provides low-ripple DC output for electronics repair and testing.

Its voltage ripple is specified at:

• ≤60mVp-p

• ≤10mVrms

The current ripple is:

• ≤10mArms

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

Electronics Repair 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 PCB repair and circuit troubleshooting, 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-related electronics repair

• Battery service and maintenance

• Charging process verification

• Electronics repair 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 rechargeable batteries are serviced or tested as part of electronics repair work.

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 a PCB, electronic module, component, or battery during repair and 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 electronics repair, the real-time display allows technicians to observe changes in current and power when a circuit is powered, making it easier to monitor the electrical behavior of the device under test.

The Ah display is particularly useful when servicing or testing rechargeable batteries, providing 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 required voltage and current parameters during electronics repair, circuit troubleshooting, and component testing.

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 circuit or device.
