Tyco Safety Products / Software House PI26 User Manual

Power supply current ratings depend on the type of power supply unit:.

With a Lien Industries power supply (SP40W1P-147), the apC/8X has a 
rating of 120-240 VAC, 50-60 Hz, 2 A, and the output is rated for a 
maximum continuous load at 12 VDC of 3.5 A. However, Software 
House recommends that you do not exceed a total current load of 2.8 A.
With a Wall Industries (Sinpro) power supply (SBU120-105), the 
apC/8X has a rating of 100-240 VAC, 47-63 Hz, 1.7 A, and the output is 
rated for a maximum continuous load at 12 VDC of 4.75 A.
