General Electric IC693PWR331E High Capacity Power Supply

The GE Fanuc IC693PWR331E serves as a high-capacity power module for Series 90-30 PLC rack systems. This unit converts a nominal 24VDC input into stable power for backplane modules. It supports a wide input voltage range, specifically from 18VDC to 30VDC. The module requires a minimum of 18VDC to initiate a successful power-up sequence. This design ensures consistent operation within diverse industrial environments where DC sources provide primary power.

Output Power Capabilities and Distribution

The power supply manages multiple voltage rails to support various system components. It delivers a primary +5VDC output capable of supplying up to 3 Amperes. Additionally, the unit provides two +24VDC output channels. One channel powers relay modules, while the other provides isolated voltage for auxiliary circuits. If the system load increases, the module can allocate the total 30-watt capacity to the +5V rail. This flexibility accommodates demanding CPU and I/O configurations.

Load Planning and Safety Guidelines

Integrators must perform detailed power budget calculations during system design. Each module installed in the PLC rack consumes a specific amount of current. You should calculate the total load for every voltage rail individually. Furthermore, it is essential to account for inrush current during the start-up phase. We recommend applying a 20% safety margin above your calculated total load. This practice prevents thermal overload and extends the service life of the unit. Proper load management ensures the stability of the entire automation control assembly.
