Frequently Asked Questions
Can I use the UHP-350R-4.2 for a redundant 4.2V DC bus in industrial control equipment?
Yes, this model is a constant voltage 4.2V power supply rated for 60A and 252W. Its built-in redundant function and DC OK feature make it appropriate for low-voltage industrial or embedded systems that are designed around a 4.2V bus.
Is the UHP-350R-4.2 suitable for high-current embedded computing or processor loads that need 4.2V?
It can fit embedded or compute hardware that specifically requires a regulated 4.2V DC source and can draw up to 60A. The fanless design and 220.0 x 62.0 x 31.0 mm low-profile housing also help where space is limited.
Can this 4.2V power supply be used in telecom or automation cabinets with worldwide AC input?
It is designed for 90-264VAC input, so it can be considered for systems that need the same 4.2V output across a broad AC input range. The key fit check is that the load must be a constant voltage 4.2V load within 252W and 60A.
What is the difference between the UHP-350R-4.2 and other UHP-350R models?
Within the UHP-350R redundant series, the listed variants are 3.3V 198W 60A, 4.2V 252W 60A, 5V 300W 60A, 12V 350.4W 29.2A, 15V 351W 23.4A, 24V 350.4W 14.6A, 36V 351W 9.75A, and 48V 350.4W 7.3A. This model is the 4.2V version, so it is the fit when the equipment is built around 4.2V rather than the other output voltages in the same series.
Is the UHP-350R-4.2 suitable for outdoor or harsh-temperature locations?
The provided specs show an operating temperature range of -30C to +70C, which supports use across a wide temperature span. The specs do not list an IP rating, so outdoor exposure is not established by the published data alone.
