Frequently Asked Questions
Can I use the HEP-320-48A for 48V DC telecom or control equipment?
Yes, this supply delivers constant 48V output up to 6.7A and 321.6W for equipment designed around a fixed 48VDC input. It is appropriate for telecom, control, and industrial electronics that operate within those electrical limits. The 90-305VAC input range is also useful where incoming AC supply varies by site.
Is the HEP-320-48A suitable for 48V industrial networking or embedded systems?
It can be used for 48V networking or embedded equipment that requires a regulated constant-voltage source and draws no more than 321.6W or 6.7A. The fanless design helps reduce maintenance in enclosed or dusty environments. Its rugged case is intended for harsher service conditions than a standard indoor supply.
Can this model be used in automation equipment exposed to vibration or temperature extremes?
It is designed for harsh environments, with 10G vibration resistance and an operating range of -55°C to +70°C. That makes it suitable for automation and industrial equipment housings where shock, vibration, or temperature swing matters. The constant-voltage 48V output still needs to match the equipment requirement.
Is the HEP-320-48A suitable for outdoor use?
This version has an IP65 water-resistant enclosure, so it is suitable for demanding indoor locations and sheltered outdoor environments where dust and water spray are present. It is not the higher-IP option in the series. The temperature rating remains -55°C to +70°C.
How does the HEP-320-48A differ from the other HEP-320 models?
In the HEP-320 range, the available outputs are 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. Selection comes down to matching the required DC voltage and current to the load while staying within the model's rated wattage.
