Damper Actuators

Hi all,

Any particular reason why a 230V damper actuator is specified over the 24VDC version and the opposite?

I would prefer mains voltage over the extra low voltage as in case of a fault it can trip a breaker, consequently visually displaying a fault.

On 24VDC given the large length of the circuit (around 70m) there is a chance the cable may arc for an extended period of time essentially qualifying for a fire hazard although low risk. The 24VDC may not trip the circuit fuse.

Supply to the damper panel is generator backed.
