The specifi ed maximum capacitive load is for each output. 2. When measuring cross regulation, the load on one output is varied from 25% to 100% while the other output is held at 100%. 3. When measuring output ripple, it is recommended that an external 0.1 µF ceramic capacitor be placed in parallel with a 10 µF electrolytic capacitor from the +VOUT pin to the -VOUT pin for single output units and from each output to common for dual output units. This is illustrated by capacitors C 6 and C7 in the typical con- nection diagram at right. 4. Transient recovery is measured to within a 1% error band for a 75% - 50% - 25% load change. 5. Output overload protection is provided by a “hiccup mode” circuit with auto- recovery. 6. The input capacitors shown in the connection diagram (C2, C3 & C4) are used on 110V input models to achieve 79 dBµV from 0.15 - 0.5 MHz and 73 dBµV from 0.5 - 30 MHz. They are ceramic, 1 µF, 250V capacitors and should be mounted as close to the unit as possible. 7. To meet the EFT and surge requirements of EN 50121-3-2, an external input capacitor is required, as shown in the connection diagram at right (C 1). For the 24 VIN models a single 330 µF/100V electolytic capacitor is recommended. For the

110 VIN models, two 100 µF/250V electrolytic capacitors connected in parallel

are recommended. 8. Operation at no-load will not damage these units. However, they may not meet all specifi cations. 9. It is recommended that a fuse be used on the input of a power supply for protec- tion. See the table above for the correct rating. Recommended Input/Ouput Components All models of the MR08xxx-RUI series include an on/off control input (Pin 1). This input uses positive logic to enable/disable the unit. When the input is “high”, the unit operates, when it is “low”, the unit is off. The chart at right gives the specifi cations for the control input. In the diagram above, an open collector switch is used (Q 1). The control input should be left fl oating if it is not being used. Shorting the control pin to the -V IN input (pins 2 & 3) will turn the unit off. Remote ON/OFF Control Parameter Min. Typ. Max.
