Product Procurement & Buyer Guide
Key Specifications for Engineers
The 1734-EPAC operates on a wide input range of 85 to 264 Volts AC. It delivers a steady 10 amps power supply current for demanding systems. This unit consumes a maximum of 15.1 Watts of power. It dissipates just 8.4 Watts of heat at full load. The thermal output sits at only 28.7 BTU per hour.
Overvoltage Protection Features
This expansion power supply protects your investment with robust safety features. It includes both MOV and fuse overvoltage protection mechanisms. The unit handles an inrush current of 2 amps for 6 milliseconds. This design effectively prevents damage from sudden power surges. It ensures stable operation for connected I/O modules.
Isolation and Environmental Tolerances
The module provides 264 Volts of continuous isolation voltage. It successfully withstands testing at 3250 Volts DC for 60 seconds. The unit operates reliably in temperatures up to 55 degrees Celsius. It works in environments with relative humidity up to 95 percent. These certifications include cULus, CE, and C-Tick approvals.
Step-by-Step Installation Guide
Pre-Installation Safety Protocol
Always turn off field wide power before connecting any wiring. This action prevents dangerous electrical arcs during installation. Verify your upstream power source matches the 120-240V AC range. Check that the DIN-rail can accommodate the module’s position.
Mounting the Expansion Power Supply
Mount the 1734-EPAC securely onto a standard DIN rail. Position it correctly to support your specific module count. The unit creates a functional partition between input and output modules. Group your modules according to their specific tasks for efficiency.
Power and Status Verification
After mounting, connect your AC field power to the designated terminals. Observe the two green LED indicators on the front panel. The first light shows field power status is active. The second indicator confirms 5 Volts of system power is present. A steady green light verifies successful power delivery to the backplane.
