Actuators, stainless steel or aluminium, for linear actuators
The actuators require two power supplies in the range 24 V to 30 V DC. The drives are equipped with a mechanical emergency manual override that enables manual operation in the event of a fault, e.g. a power failure. The drives can also be configured using the support tool via the service plug (mini-USB).
Application
The actuators are not meant for continuous operation at nominal torque, but for short-time operation. The following intervals apply to the duty cycle (DC): At 100% load torque, the DC is 25%, which corresponds to a rated operating mode S2 with a base time of 4 minutes: duty cycle (DC) = 1 minute, followed by a pause duration (PD) of 3 minutes. With reduced load torque, the DC can be up to 50% depending on the ambient conditions and application. Other operating modes are protected by l2t and temperature monitoring and an adjustable current limiter. A briefly increased breakaway torque is permissible as part of this protection.
