Peak load lasting <30 s with a maximum duty cycle of 10%, average output power not to exceed nominal power. 2. Add suffix -S to model number to denote chassis mount with screw terminal type, e.g. ECE40US12-S. Only available with ECE40 models. 3. A screw terminal versions (-S) is available with DIN Clip attached. Add suffix `D', e.g. ECE40US24-SD. DIN Rail mounting clip is available as a separate item, order code ECL25/30 DIN CLIP. 4. Average of efficiencies measured at 25%, 50%, 75% & 100% load with 230 VAC input. 5. 3.3 & 5 V ECE40-S versions meet 75 mV pk-pk with 20 MHz bandwidth and 0.1 F capacitor across output terminals.
