Model Selection Guide Model Number B1501ERW B1502ERW B1503ERW B1504ERW B1505ERW B1506ERW B1511ERW B1512ERW B1513ERW B1514ERW B1515ERW B1516ERW B1521ERW B1522ERW B1523ERW B1524ERW B1525ERW B1526ERW Notes: 1. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 1 F to 10 F) be placed from the +Vout to the -Vout pins. 2. The remote On/Off control is referenced to ground. It is recommended that connection to the pin be made through a 1k resistor and diode (1N4148). If it is not used, the control pin should be left open. 3. These units should not be operated with a load under 10% of full load. Operation at no-load will not damage the unit, but they may not meet all specifications. 4. These converters are specified for operation without external components. However, in some applications the addition of input/ouput capacitors will enhance stability and reduce output ripple. For applications requiring very low output noise levels, a simple LC filter should be effective. 5. These units should not be operated over +85C (see derating curve). Exceeding +85C may damage the unit. 6. 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.

To adjust the output DOWN, connect a 5%, 3W resistor between the plus output pin and the Vout trim pin. To adjust the output UP, connect a 5%, 3W resistor between the minus output pin and the Vout trim pin. For UP/Down trimming capability, connect a 10 kW potentiometer between the plus and minus outputs with the wiper arm connected to the Vout trim pin. * 292 Page Street Ste D Stoughton, MA 02072 TEL: (781) 344-8226 * FAX: (781) 344-8481 E-Mail: sales@micropowerdirect.com |
