SUN YEH Electric actuator

Features

Enclosure : – IP 67: Waterproof and dust-proof enclosures. – NEMA 4X: Waterproof and dust-proof enclosures. – Material: Dry powder coating aluminum alloy. Motor: – Standard extended duty cycle induction motor. F insulation class for all models. (OM-A, OM-A-M, BM-2, and OM-1 to OM-13.) – Built-in thermal protection (135°C) prevents motor burning out. Position Indicator: – All models have continuous mechanism position indicator on the top of actuator cover. Manual Override : – Non-clutch design, the manual operation can be operated without any lever, clutch or brake upon power outage. – When electric motor is operating, manual hand-wheel won’t rotate for person safe purpose.
