Frequently Asked Questions - RPT-75B Mean Well

What type of power supply is the Mean Well RPT-75B?

The RPT-75B is a medical switching power supply designed for PCB mounting, suitable for applications requiring medical safety approvals.

What are the input voltage requirements?

The unit accepts a universal input of 90-264VAC or 127-370VDC, making it compatible with global mains voltages.

How should I mount the RPT-75B?

It is a PCB mount type. Ensure at least 5mm insulation distance on the bottom and 15mm clearance around the unit. Use a Mylar film if necessary.

What wire gauge should I use for connections?

For currents up to 10A, use 18-14 AWG wire. For higher currents (up to 40A), refer to the manual's table. Ensure all strands enter the terminal and screws are tightened securely.

- 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

(2) Please do not install the units in places with high ambient temperature or near fire source. The maximum ambient temperature, please refer to their specifications.
(3) Output current and output wattage must not exceed the rated values on specifications.
(4) To avoid risk of electric shock, for class I products, the ground (FG) must be connected to protective earth.
(5) The Enclosed, Modular and PCB units are designed in accordance with EMC regulations and the related test reports are available by request. Since they are belong to component power supplies and will be installed inside system enclosure, when they are integrated into a system, the EMC characteristics of the end system must be re-verified again.
