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 F required to meet quoted ripple & noise. Minimum load of 25% required to meet quoted specifications.
