Notes
1. For dual inline package replace ‘S’ in model number with ‘D’.
2. For optional 3 kV isolation add suffix ‘-H’ to the model number.
3. For dual output delete suffix ‘A’ & split output currents equally between rails.
4.
5.
6.
7.
For optional Remote On/Off on SIP models, add suffix ‘-R’ to model number.
For optional metal case, add suffix ‘-M’ to model number.
Output capacitor of 100 µF required to meet quoted ripple & noise.
Minimum load of 25% required to meet quoted specifications.
Dimensions are in inches (mm)
Weight: Plastic case = 4.5 g
Metal case = 6.5 g
