Frequently Asked Questions
Can I use the RS-75-48 for 48V telecom or communications equipment?
It is suitable for equipment that specifically requires a constant 48V DC input and draws no more than 1.6A or 76.8W. That makes it relevant for lower-power telecom and communications hardware designed around a 48V DC bus.
Is the RS-75-48 a good fit for 48V industrial networking or control devices?
Yes, if the device requires 48V DC and the load remains within the unit's 1.6A maximum output current and 76.8W rating. As a constant-voltage model, it is intended for equipment that expects a regulated 48V supply rather than a constant-current source.
Can this power supply be used for compact 48V automation subsystems inside a machine or panel?
It can fit enclosed automation assemblies that need a 48V rail and have moderate power demand up to 76.8W. The 129.0 x 98.0 x 38.0 mm form factor is also useful where panel space is limited.
Would the RS-75-48 work for a 48V test station or lab fixture?
For fixed 48V DC fixtures, it can be appropriate as long as the connected equipment stays within 1.6A and 76.8W. The 88-264VAC input range also supports use in facilities with different AC input standards.
Can the RS-75-48 be used outdoors or in dusty areas?
No IP rating is listed for this model, so it should be used in a protected enclosure rather than directly exposed outdoor, wet, or dusty locations. Its environmental rating covers temperature from -25C to +70C, but that does not indicate sealed ingress protection.
What are the differences between the RS-75-48 and the other RS-75 models?
The RS-75 family includes RS-75-3.3 at 49.5W, 3.3V, 15A; RS-75-5 at 60W, 5V, 12A; RS-75-12 at 72W, 12V, 6A; RS-75-15 at 75W, 15V, 5A; RS-75-24 at 76.8W, 24V, 3.2A; and RS-75-48 at 76.8W, 48V, 1.6A. The output voltage changes across the series, and the available current changes with it.
