Frequently Asked Questions
Can I use the HEP-185-48 for 48V telecom, networking, or industrial communications equipment?
Yes, this model provides 48V constant voltage at up to 3.9A, with a total output rating of 187.2W. That matches many 48VDC systems used in communications and industrial networking equipment. The 90-305VAC input also supports installation across a wide range of AC supply conditions.
Is the HEP-185-48 suitable for 48V embedded controllers or distributed automation nodes?
It can be used where the equipment is designed for a fixed 48VDC source and the combined load stays within 187.2W and 3.9A. The constant-voltage operating mode is appropriate for 48V bus-powered electronic systems. Its fanless design also helps in applications where dust, vibration, or maintenance access are concerns.
Can the HEP-185-48 power a 48V LED or signage system in a harsh location?
Yes, for 48V constant-voltage lighting or signage loads that remain within 187.2W and 3.9A. This version is IP68 rated and specified for -55°C to +70°C operation, so it is aimed at tougher indoor and outdoor environments. That makes it better suited to exposed locations than a non-sealed 48V supply.
Is the HEP-185-48 appropriate for outdoor or washdown-adjacent environments?
This is the IP68 version, so it is the more sealed option for demanding environments. It is also rated for operation from -55°C to +70°C and uses a rugged metal case with no fan. Those characteristics make it well suited to harsh industrial or outdoor service conditions.
How does the HEP-185-48 compare with the rest of the HEP-185 family?
The HEP-185 family covers 156W at 12V and 13A, 172W at 15V and 11.5A, 187.2W at 24V and 7.8A, 187.2W at 36V and 5.2A, 187.2W at 48V and 3.9A, and 186.3W at 54V and 3.45A. The HEP-185-48 and HEP-185-48A share the same 187.2W, 48V, and 3.9A electrical output. The practical difference between family members is the DC voltage and matching current rating required by the load.
