Hi MG. I’ve never really thought about it. But in my mind the choice depends on various factors. A 230V one is likely to use less energy when idle or under low load, but a 24VDC one may use less energy when operating or under high load. A 230V one may pose a higher risk of electric shock or fire than the 24 V option bur the 24VDC one may be more prone to interference or damage. But I don't know for sure why one is specifically ask for.
