Key Features

Adjustable Regulated Output for PCB & IC Testing:

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

As a regulated power supply for PCB & IC power-up testing, the SPS305C allows technicians and engineers to set the required voltage and current before applying power to the device under test. This is useful when verifying whether a PCB or electronic module can start and 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 regulated output makes the SPS305C suitable for powering PCBs and electronic circuits during power-up testing, monitoring current consumption, and verifying operating conditions during circuit development and troubleshooting.

Over Current Protection for PCB & IC Power-Up Testing:

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

During PCB and IC 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:

• PCB power-up testing

• IC evaluation board testing

• Circuit debugging

• Electronic component testing

• Module power-up testing

• Prototype circuit testing

The OCP function helps provide additional protection when engineers are powering up newly developed or potentially faulty electronic circuits.

Battery Charging Function for Electronics Testing:

In addition to regulated 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

Although PCB and IC power-up testing is the primary application, this function can also be useful when testing battery-powered electronic products, battery charging circuits, and electronic modules that incorporate rechargeable batteries.

Low-Ripple Regulated DC Output:

The SPS305C provides low-ripple DC output for PCB, IC evaluation, and electronic circuit testing.

Its voltage ripple is specified at:

• ≤60mVp-p

• ≤10mVrms

The current ripple is:

• ≤10mArms

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

PCB & IC 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 PCB power-up and IC evaluation, 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 battery-powered PCBs, electronic modules, or charging circuits are being tested.

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, IC evaluation board, electronic module, or other device during power-up 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 PCB and IC power-up testing, the real-time display allows engineers to observe changes in current and power when a circuit 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 PCB testing, IC evaluation, circuit debugging, 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.

✦ USB-A & USB-C Fast Charging Output
