FNIRSI® IPS3608 AC-DC Intelligent Digital Control Power Supply

FNIRSI® IPS3608 AC-DC Intelligent Digital Control Power Supply

Product Description

The FNIRSI IPS3608 is a programmable bench power supply built for technicians, engineers, and hobbyists who need precise, stable DC power for testing, repair, and development work. Using digital control technology to convert AC input into clean, adjustable DC output, it replaces the imprecise dials and analog drift of older linear supplies with a fully digital interface capable of fine, repeatable adjustments.

Output covers a 0–36V voltage range and 0–8A current range, delivering up to 285W of total power, with a setting resolution of 0.01V and 0.001A for genuinely fine-grained control over test conditions. The supply automatically switches between constant voltage (CV) and constant current (CC) modes depending on the load, which keeps output stable whether you're powering a sensitive circuit or charging a battery pack that demands a shifting current profile. Ripple is held below 10mV, an important detail for anyone powering noise-sensitive analog or RF circuits where a dirty power rail can introduce measurement errors or unexpected circuit behavior.

Safety is handled through a comprehensive set of protection mechanisms, including overvoltage, overcurrent, overpower, overtemperature, undervoltage, short circuit, input reverse connection, and output reverse injection protection. This layered protection is particularly valuable in a lab or repair setting where miswired connections or unexpected load faults are a real possibility, reducing the risk of damage to both the supply and the device under test.

The IPS3608 supports up to six stored presets covering voltage, current, and protection limits, letting users switch quickly between commonly used test configurations rather than re-entering values each time. A dedicated RUN/STOP button enables or disables the main output with a single press, illuminating green when active, which makes it easy to confirm output status at a glance. All of this is monitored through a 2.8-inch TFT color display with adjustable backlight brightness, showing real-time voltage, current, power, and temperature readings.

Beyond standalone bench use, the IPS3608 connects to companion PC software that allows real-time parameter monitoring, voltage and current curve recording, and preset management, along with more advanced functions like sequential output control and voltage/current scanning for automated test sequences. It also includes USB-A and USB-C ports supporting fast charging protocols such as PD, QC, FCP, SCP, and AFC, letting the unit double as a fast charger test bed or general-purpose charging source.

Housed in a full CNC-machined aluminum enclosure with an intelligent active cooling fan, the IPS3608 is built for durability and sustained thermal performance under repeated heavy use, making it a solid fit for personal labs, repair shops, and light industrial testing environments.
