Ac or dc electric strike?

Have you tried disconnecting the strike (just one wire is adequate) and repeat the voltage measurements above?
A very quick google search for the resistance of the 203 strike comes up with 8 (or 17)Ω which would be 3(1.4)A at 24V, my guess is the PSU is incapable of providing 3(1.4)A.
Actually perhaps you should disconnect the strike and measure the voltage on the cable.
