Frequently Asked Questions
Q: Is this switching power supply module compatible with both 110V and 220V mains systems?
A: Yes. The module accepts a wide AC input range of 85–265VAC (and 100–300VDC), making it fully compatible with both North American 110V and European/international 220–240V mains supplies without any manual switching required.
Q: What does "isolation" mean on this power supply module, and why does it matter?
A: Galvanic isolation means there is no direct electrical connection between the AC input and the DC output. This provides an important safety barrier, protects your downstream circuits from mains-level faults, and reduces noise — critical for sensitive electronics and microcontroller-based projects.
Q: Does the module recover automatically from a short circuit?
A: Yes. Short-circuit protection operates in hiccup mode — the module automatically reduces output during a fault and restores normal operation once the fault is cleared, protecting both the module and connected devices without manual intervention.
Q: What output voltage variants are available?
A: This module is available in six output voltages: 5V (20W), 9V (36W), 12V (36W), 15V (36W), 24V (36W), and 36V (36W). Select the variant that matches your application's DC voltage requirement at checkout.
Q: Can this module be used in industrial or outdoor enclosures?
A: The module operates from -20°C to +70°C with up to 90% non-condensing humidity, making it suitable for integration into industrial control panels, custom enclosures, and moderately demanding environments. It is not itself waterproof, so install it within a suitably rated enclosure for outdoor use.
