Notes

1. 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 µF capacitor across output terminals.

1. Dimensions in inches (mm).

2. Weight: ECE20: 0.13 lbs (60 g)

ECE40: 0.33 lbs (150 g)

ECE40 Optional Screw Terminal: 0.37 lbs (170 g)

3. Tolerances: x.xx = ± 0.02 (x.x = ± 0.5), x.xxx = ± 0.01 (x.xx = ± 0.25)
