Vik – I’m not an expert, but I believe that switched mode power supplies output DC. You should be able to test your power supply with your meter to determine if it is outputting AC or DC.
The new power supply looks like it should work. It has 24V AC output at 750mA. The one Ray sells here is 24V AC at 500mA so your is capable of supporting a higher current load.
