Notes:
Derating Curve
1. When measuring output ripple & noise, it is recommended that an external
ceramic capacitor (0.47 µF typ.) be placed from the +VOUT to the -VOUT pins for
single output units and from each output to common for dual output models.
2. Transient recovery is measured to within a 1% error band for a load step
change of 75% to 100%.
3. Free air convection is typically 20 LFM. The units should not be operated in
still air (0 LFM).
4. Exceeding the absollute ratings could damage the unit.
5. It is recommended that a fuse be used on the input of a power supply for protection.
See the Model Selection table above for the correct rating.
Remote ON/OFF
Mechanical Dimensions
The MD200x-xxRU remote control input (pin 3) is current controlled. The unit oper-
ates when this input is open. When the input is “high” (current is flowing into the
pin), the converter shuts down. The input current to this pin should be kept between
2 mA and 4 mA. The diagram above shows a simple connection for the control pin.
Using a value of 1 kꢀ for R1,a voltage level of 5V - 9V may be used to control the
unit. The table below gives specifications for this feature.
