Wireless DC Motor & Linear Actuator Control
To answer your first question: NO!

1) motor: 24v, 1 amp = 24 watts

2) Linear actuater: 50 watts (according to eBay link)

Total = 74 watts. 50 watts continuous (motor running) with ocassional bumps to 74 watts when the linear actuater kicks in. 

Power supply: 24 v, 2 amps = 48 watts

48 &lt; 74 so power supply is not big enough!
