Frequently Asked Questions
Can I use the HEP-320-48 for 48V telecom or industrial networking equipment?
Yes, it is a constant-voltage 48V supply rated for 321.6W and 6.7A, which suits 48V equipment that stays inside those limits. That makes it relevant for telecom, industrial networking, and control gear designed for a regulated 48VDC bus. The wide 90-305VAC input range supports deployment across different AC supply environments.
Is this model suitable for 48V embedded computing or communications systems in harsh locations?
It can be used for 48V embedded or communications equipment that requires fixed-voltage DC and draws no more than 6.7A or 321.6W. The fanless design, metal case, and 10G vibration resistance make it more appropriate for demanding field or industrial installations. Its certifications include CB, CE, EAC, and UL.
Can the HEP-320-48 be used for 48V automation loads in outdoor equipment housings?
This version is suited to harsh-environment 48V automation applications because it combines constant-voltage output with an IP68 rating. The operating temperature range of -55°C to +70°C also supports exposed or unconditioned installations. Load requirements still need to remain within 321.6W and 6.7A.
Is the HEP-320-48 appropriate for wet or fully exposed environments?
The unit is rated IP68, so it offers stronger environmental protection than the IP65 versions in the same series. That rating, together with the -55°C to +70°C operating range, makes it the better choice for exposed outdoor or washdown-prone conditions. It is built specifically for harsh-environment use.
How does the HEP-320-48 compare with the other HEP-320 voltage models?
The HEP-320 family includes 264W at 12V 22A for HEP-320-12 and HEP-320-12A, 285W at 15V 19A for HEP-320-15 and HEP-320-15A, 320.16W at 24V 13.34A for HEP-320-24 and HEP-320-24A, 320.4W at 36V 8.9A for HEP-320-36 and HEP-320-36A, 321.6W at 48V 6.7A for HEP-320-48 and HEP-320-48A, and 321.3W at 54V 5.95A for HEP-320-54 and HEP-320-54A. The 48V versions trade lower current for higher output voltage while staying in the same approximate 320W class.
