PS914 Power Supplies

Output

• 4-amp, Class 2, filtered and regulated power
• Clean, consistent power output helps protect the sensitive circuitry of downstream products
• Overload protection prevents too much current being pulled by an overload of devices
• 12/24 VDC output field selectable with plug-in jumper
• Externally visible LED indicator provides visual status on AC input 
• Ability to provide continual power with battery backup

Input

• Universal 120-240 VAC, fused primary input
• Externally visible AC input indicator with isolated SPDT contacts
• Battery back-up board auto-selects voltage
• LED indicator provides visual status on DC output

Installation

• Order to specification or field configure; option boards use polarized plug-in connectors to simplify in-field expansions
• Option boards enable basic fuse protection, simple relay, advanced logic with sequencing and timing, panic device control, fire alarm relay and battery backup 
• Cabinet accommodates 1 or 2 batteries, up to 2 option boards, plus fire alarm relay and battery backup board
