High-Performance Adjustable DC Power Supply 0-30 V 0-5 A

With the dedicated software the FNDPS150 is not just a compact bench power supply: connect it to a PC over USB and it becomes an advanced measuring and control instrument, perfect for laboratory work, production testing, electronics development or the most demanding maker projects.

The software gives you a complete, intuitive interface from which you can easily manage every function of the power supply and reach advanced options that go well beyond manual control:
Real-time monitoring – voltage, current, power and temperature are always under control, constantly updated and available for logging.
Waveform display – you can watch how voltage and current change over time on detailed graphs. The zoom function lets you examine every detail of the curve, to check exactly how your circuits behave.
Configurable presets – save up to 6 voltage and current combinations and recall them with one click. Perfect for switching quickly between set-ups without entering the parameters again every time.
Advanced measurements – the software automatically measures the capacity (Ah) and the energy (Wh) delivered during a work session, useful for checking the real runtime of a battery or the consumption of a device.
Adjustable brightness – set the screen brightness to suit your working environment, with 14 levels available.
Full device information – firmware version, operating temperature, communication status and other diagnostic data are always at hand.
Remote command – switch the power supply output on and off straight from the software, to work safely and in full control.

Advanced functions for automated testing and development

The real strength of the software is the ability to program and automate the power supply, making even the most complex tests straightforward:
Sequential output
Set a series of voltage and current values that the unit will run automatically one after the other, with repeat cycles (loops) if required. Ideal for burn-in tests, simulating changing conditions or testing components that have to be stressed dynamically.
Current sweep
Hold the voltage constant and sweep the current automatically over the range you prefer, with adjustable step and custom dwell times. Perfect for studying how electronic circuits respond in constant-current mode.
Voltage sweep
In the same way, you can fix the current and sweep the voltage automatically, useful for example to test variable supplies or to find the operating threshold of a given component.

Note: while the PC software is connected, the manual controls on the power supply are disabled to avoid conflicts — everything is managed from the computer.

The basic interface

① Waveform display area: lets you record, save and delete the voltage and current traces. You can zoom the waveform in and out with the mouse wheel while a single trace is displayed.

② Output voltage and current settings: lets you change the voltage and current values of the preset group currently selected. Changes are temporary and are lost when the unit is restarted.

③ Data groups (presets): lets you quickly select preset voltage and current values. Up to 6 different combinations can be saved.

④ Measurement switch: measures the capacity (Ah) and the energy (Wh) delivered. The data is reset every time the software is closed and reopened.

⑤ Brightness adjustment: 14 levels available; the highest level is full backlight.

⑥ USB interface information: shows the device model, firmware version, communication speed and port, device address and connection status.

⑦ Basic operating information: shows in real time the input voltage, the output voltage, the output current, the power delivered and the internal temperature. The ON/OFF state of the power supply can also be managed from this section.

The advanced interface

① Sequential output:
Runs a sequence of voltage and current parameters automatically, according to the range of sequence numbers and the loop count you set.
Clicking “Start” launches the automatic sequence (the other interfaces are locked while it runs). Values already set are marked “OK”, while those still to be run show as “Waiting”. “Pause” suspends the output while holding the last active state, and “Continue” resumes the sequence after the programmed delay.
In Manual mode, clicking “Single step” lets you advance one step at a time under your own control; if you stop the test, the output stays on the current parameter.

② Current sweep:
With the voltage fixed, sweeps the current automatically over a defined range, according to a step value and a dwell time you can set (typically used in constant-current mode).

• The voltage must be set > 0 V
• Clicking “Start” begins the sweep (the other interfaces stay inactive). “Stop” ends the sweep and switches the output off.

③ Voltage sweep:
With the current fixed, sweeps the voltage automatically over a defined range, according to a step value and a dwell time you can set (typically used in constant-voltage mode).

• The current must be set > 0 A
• Clicking “Start” begins the sweep (the other interfaces stay inactive). “Stop” ends the sweep and switches the output off.

• Protection: overvoltage, overcurrent, undervoltage, overload, overheating, input/output reversal, short circuit
• PC software connection: supported
• Weight: about 178 g
• Dimensions: 106 x 76 x 28 mm
