Notes:
1. Output load regulation is specified for a load change of 10% to 100%.
2. These units should not be operated with a load under 10% of full load. Operation at no-
load may cause damage to the unit.
3. These converters will operate without external components. However, when measuring out-
put ripple, it is recommended that
an external ceramic capacitor Input Output
Vin Vout
be placed from the +Vout pin to Capacitor Capacitor
the -Vout pin. An input capacitor 3.3 VDC 4.7 µF 3.3 VDC 10.0 µF
will enhance stability over tem-
perature and input line variations. 5 VDC 4.7 µF 5 VDC 10.0 µF
Recommended capacitor values 12 VDC 2.2 µF 9 VDC 4.7 µF
are given in the table above. For 24 VDC 1.0 µF 12 VDC 2.2 µF
applications requiring very low
output noise levels, a simple LC 15 VDC 1.0 µF
filter should be effective.
4. After an output short circuit, the input power must be recycled to operate the unit.
5. Given for frequency range of 5 to 500 Hz and PSD of 0.0248 g2/Hz.
Tested on X, Y & Z axis for 60 minutes.
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.
