Notes:
1. Transient recovery is measured to within a 1% error band for a load step change of 75% to 100%.
2. For proper operation, a minimum load of 10% of maximum output current on each output is required.
3. When measuring output ripple, it is recommended that an external 0.1 uF ceramic capacitor be placed from the +Vout pin (pin 3)
to the -Vout pin (pin 5) for single output units and from each output (pin 3 & pin 5) to common (pin 4) for dual output models.
4. For further protection, it is recommended that an external slow-blow fuse be added to the converter input line. The fuse rating
should be 1500 mA for 48V input models or 3000 mA for 24V input models.
