Power Requirements 

 

Power Conversion:  P = power (watts), I = current (amps), V = (volts)

(V)  

 

Power Input: 

 
17-30 Volts DC continuous power. The circuit board consumes about 2.5 watts. This 
does  not  include  any  electric  valves  that  may  accompany  the 

Presto

.  The  voltage    

delivered to external valves or solenoids is the same as the input voltage. Therefore, 
care should be taken to be sure the supply voltage matches the specifications of the 
valves or solenoids.  
 
 

Hangers  and  mounting  brackets  are  included  but  not  shown.  When  the
