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.
