Notes
1. Add suffix ‘D’ for detachable connector option e.g. DSL240PS24-ID.
2. Typical efficiency at 230 VAC and full load.
3. Peak load is for a maximum of 3 s with 20% duty cycle. Average power is not
to exceed nominal output power.
4. Output current should be limited so that nominal output power is
not exceeded.
