Load regulation is specified for a load change of 20% to 100%. 2. Overload protection is current limiting. The unit recovers automatically when the fault is removed. 3. Over voltage protection is a shut down type. The unit recovers automatically when the fault is removed. 4. The MDR-24 meets class 1 safety requirements with a proper PE connection. To insure compliance to EN60950, it must be possible to switch off the unit using suitable disconnection device external to the power supply. 5. It is recommended that a fuse be used on the input of a power supply for protection. For the MDR-24 series, a 250 VAC 3.15A is recommended.

All wires should be 14-25 AWG. For safety, all wires should be stripped approximately 7 mm. and any connections to the supply should only be made with the system power off. Do not operate without a proper PE connection. To allow proper ventilation, the MDR-24 series should be mounted so they are vertically orientated with approximately 2 inches (50 mm) of clearance above and below the unit. No minimum spacing is required between units. Ventilation holes should not be covered and proper derating should be followed. Connections Pin Function 1, 2 DC Output (+V) 3, 4 DC Output (-V) 5, 6 Earth (PE) 7 AC/Neutral (N-) 8 AC/Line (L+) Mechanical Dimensions Installation/Removal Install To mount the unit to the DIN rail, tilt the unit rearwards from the top, fitting the mount over the top of the rail. Press back on the bottom front of the unit until it locks in place on the rail. Remove To remove the unit from the rail, pull the removal clip at the bottom rear of the unit downward with a screw driver. With the clip down, lift up on the unit from the bottom front until it clears the rail. Before installation or removal all wiring should be disconnected and the main power to the system shut off.
