Product Description

The SPPS305D power supply is a versatile and advanced tool for those who require precise control over electrical power in their projects. Equipped with an LED display, this power supply provides a clear and user-friendly interface that shows crucial information such as voltage, current, and power output.

A standout feature is the 4 memory channels, allowing users to store and recall customized output profiles. This functionality is ideal for quickly switching between specific voltage or current settings, optimizing work in different scenarios.

Precise adjustment of voltage and current is achieved through a knob that allows both fine and coarse tuning. This flexibility is essential to adapt to a wide variety of applications and load requirements.

The presence of communication ports, such as USB and RS232, facilitates connection to a PC, enabling remote control and advanced monitoring. Additionally, the front USB port dedicated solely to power provides convenience by allowing the direct charging of devices from the power supply.
