Frequently Asked Questions

What makes a linear power supply better for certain applications?

Linear power supplies like the UTP3315TFL-II provide significantly cleaner power with lower noise and ripple compared to switching power supplies. This clean power is essential for sensitive analog circuits, audio applications, and precision measurement systems where even small power fluctuations can affect performance or test results. The linear regulation technology eliminates the high-frequency switching noise that can interfere with sensitive electronics.

Can this power supply be used for electroplating or electrolysis?

Yes, the UTP3315TFL-II is well-suited for electroplating and electrolysis applications. The constant current mode allows you to set a precise current level that remains stable regardless of resistance changes in the electrochemical cell. The 5A maximum current is sufficient for many small to medium-scale electroplating and electrolysis projects.

How does the current limiting protection work?

The current limiting protection automatically restricts the output current to your preset maximum value. When the load attempts to draw more current than your set limit, the power supply transitions from constant voltage (CV) to constant current (CC) mode, maintaining the current at your preset limit while reducing the voltage as needed. This protects both the power supply and your connected devices from overcurrent conditions.

Is this power supply suitable for powering automotive electronics during bench testing?

Yes, the UTP3315TFL-II is ideal for testing automotive electronics components. The 0-30V range covers the typical 12V and 24V automotive systems, while the 5A capacity is sufficient for most control modules, sensors, and smaller actuators. The clean power output ensures accurate testing conditions, and the current limiting protection helps prevent damage when testing unknown or potentially faulty components.

What is the difference between the UTP3313TFL-II and UTP3315TFL-II models?

The primary difference is the current capacity and power rating. The UTP3315TFL-II offers 0-5A output (compared to 0-3A in the UTP3313TFL-II) and 150W of power (versus 90W). The UTP3315TFL-II also has slightly different specifications for load regulation and ripple. This higher capacity makes the UTP3315TFL-II more suitable for applications requiring greater current, such as testing power-hungry devices or systems.
