Frequently Asked Questions - RPS-45-48 Mean Well

What is the input voltage range for the RPS-45-48?

The typical input voltage range for Mean Well RPS series is 100-240 VAC (universal input). Always check the specific model label.

Can I use the RPS-45-48 in a medical device?

Yes, the RPS-45-48 is a medical switching power supply designed to meet IEC/EN 60601-1 safety standards for medical electrical equipment.

What is the output current of the RPS-45-48?

At 48 V output and 45 W, the nominal output current is 0.94 A (45W / 48V).

How should I mount the PCB power supply?

Mount with at least 5 mm insulation distance from the board to the system and 15 mm clearance around the unit. Use a Mylar film between PCB and system if necessary. Ensure proper ventilation.

What wire size should I use for connection?

- Installation

(1) Enclosed Type

(a) Before any installation or maintenance work, please disconnect your system from the utility. Ensure that it cannot be re-connected inadvertently!
(b) Mounting orientations other than standard orientation or operate under high ambient temperature may increase the internal component temperature and will require a de-rating in output current. Please refer to the specification sheets to receive the optimum mounting position and information about the de-rating curve.
(c) Fans or ventilation holes must be kept free from any obstructions. Also a 10-15 cm clearance must be kept when the adjacent device is a heat source.
(d) Keep enough insulation distance between mounting screws and internal components of Enclosed units. Please refer to case drawing on specifications to receive the maximum length of mounting screw.
(e) Recommended wires of Enclosed units are shown as below.

AWG	18	16	14	12	10
Rated Current of Equipment (Amp)	6A	6-10A	10-16A	16-25A	25-32A	32-40A
Cross-section of Lead( mm^2 )	0.75	1.00	1.5		2.5	4
Note: The suggested maximum current above only suit for 1-4 strips, 5 or more strips should not exceed 80% of current rating.
