TECHNICAL DATASHEET
PMT Panel Mount Power Supply
48V 350W 1 Phase / PMT-48V350W1A
Assembly & Installation
Side Mounting: Fig. 2 and Fig. 3 show the mounting hole locations for power supply assembly onto a metal mounting surface. The
Ⓐ
power supply shall be mounted on minimum of 4 mounting holes using M4 screw maximum 5mm
4). This is to maintain a safety distance between the screw and internal components.
Base Mounting: Fig. 2 and Fig. 3 show the mounting hole locations for power supply assembly onto a metal mounting surface. The
Ⓑ
power supply shall be mounted on minimum of 4 mounting holes using M4 screw maximum 4mm (0.16 inch) length (Refer to Fig.
4).

Base Mounting (Horizontal)
• Use flexible cable (stranded or solid) of AWG No. 22-12. The input/output connectors' allowable current is 23A max per pin. User
should calculate and select the suitable wire specification (type/quantity/diameter) according to actual output current. The torque at
the connector shall not exceed 13Kgf.cm
Recommended mounting torque of the product and its mounting accessories is 9~12Kgf.cm (7.81~10.42 lbf.in).

Fig. 3 Mounting Hole Locations and the Safety Distance
For safety reasons, please ensure the mounted device is kept at ≥ 4mm (0.16 inch) safety distance at all sides from other components
and equipments. In addition, to ensure sufficient convection cooling, always maintain a distance of ≥ 20mm (0.79 inch) from fan ventilated
surfaces while the device is in operation. Please insert an insulation sheet between the system and product, if the safety distance is <
4mm (0.16 inch).
