Frequently Asked Questions
Can I use the UHP-350-12 for a 12V industrial control panel or automation enclosure?
Yes, this model provides constant-voltage 12V output at up to 29.2A, with 350.4W total power. That makes it appropriate for 12V industrial control, automation support circuits, and embedded cabinet power where the load is designed for 12V DC.
Is the UHP-350-12 suitable for 12V CCTV, access control, or security hardware?
It can be used where the connected equipment requires a 12V constant-voltage source and the total demand stays within 350.4W and 29.2A. This output class is often considered for centralized 12V security and monitoring systems.
Can this power supply run 12V embedded electronics or low-voltage machine accessories?
Yes, the 12V output and 350.4W capacity make it relevant for embedded electronics, low-voltage controllers, and machine accessories built around 12V DC. Its 220.0 × 62.0 × 31.0 mm low-profile housing also helps in tighter equipment spaces.
Is the UHP-350-12 okay for outdoor installations or only indoor use?
The operating temperature range is -30°C to +70°C, but no IP rating is listed in the provided specs. That supports use across a broad temperature range, while outdoor exposure or direct moisture resistance should not be assumed from this data.
How does the UHP-350-12 compare with other UHP-350 output options?
In the UHP-350 family, the listed versions are 198W 3.3V 60A, 252W 4.2V 60A, 300W 5V 60A, 350.4W 12V 29.2A, 351W 15V 23.4A, 350.4W 24V 14.6A, 351W 36V 9.75A, and 350.4W 48V 7.3A. The main difference is output voltage and current while staying in the same slim, fanless series class.
