Notes
1. Convection-cooled, max output power must not exceed 120 W for
combined V1, V2, & V3
2. For V3 5 V standby, Power OK & Inhibit, add suffix ‘-A’ to model number.
3. For covered versions, add suffix ‘-C’ to model number or order part no.
ECM140 COVER KIT for standalone cover. Not suitable for use in
class II installations.
