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. All 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)
