When measuring output ripple, it is recommended that an external 10.0 µF ceramic capacitor be placed from the +Vout pin to the -Vout pin. For noise sensitive applications, the use of 47 µF capacitors will reduce the output ripple. 2. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%. 3. The Remote On/Off Control input (Pin 3) is referenced to -Vin (Pin 1). Connection to the pin should be made through a 1k⍀ resistor and diode (1N4148). If it is not used, the control pin should be left open. 4. Operation at no-load will not damage these units. However, they may not meet all specifications. 5. The +sense and -sense connections will compensate for up to 5% of Vout. When not used, they should be connected directly to the appropriate output pin (+sense to +Vout and -sense to -Vout). 6. To improve performance and stability, a simple external LC filter can be added to the unit input. Typical component values would be 1.0 µH/10A & 1,000 µF/25V for 12V input models; 2.2 µH/10A & 1,000 µF/50V for 24V input models; and 74.7 µH/5A & 1,000 µF/100V for 48V input models. 7. It is recommended that a fuse be used on the input of a power supply for protection.

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. To calculate the correct resistor value (in k) use: 3.3 VOUT UP RADJ = (VOUT - 1.24) x (2.87) VADJ - VOUT - 10 Other VOUT UP RADJ = (VOUT - 2.5) x (2.87) VADJ - VOUT - 10 Down RADJ = (VADJ - 1.24) (VOUT - 1.24) x 2.87 - 10 VOUT - VADJ Other VOUT Down RADJ = (VADJ - 2.5) (VOUT - 2.5) x 2.87 - 10 VOUT - VADJ 3.3 VOUT 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.
