Inrush current is given for a cold start at 25°C. 2. Over voltage protection is provided by a zener diode clamp. 3. Output short circuit protection is provided by a “hiccup mode” circuit. The unit recovers automatically when the fault condition is removed. 4. Output overload protection is provided by a fold back current limiting circuit with auto-recovery. A long-term overload could damage the unit. 5. EMI characteristics are specified without external components. 6. Operation at no-load will not damage these units. However, they may not meet all specifications. 7. Applying a voltage level of 4.5 to 12.5 VDC across the control terminals (see mechanical diagram) will turn the unit off. When the control inputs are left open, the unit will operate normally. 8. The MDR-120S is designed for mounting on a standard 35 mm DIN rail (TS35). 9. It is recommended that an external slow blow fuse also be used on the input for protection. Contact the factory for more information.
