The 5432-157 is a Power Supply Module designed and manufactured by Woodward for use in high-reliability digital governor and turbine control chassis. Serving as a crucial power distribution node within the controller rack, this module receives raw auxiliary plant power and converts it into fully stabilized, low-noise DC operating voltages required for CPU processing boards, transceiver circuits, and field interface cards.
A key feature of the 5432-157 is its controlled sequential power delivery. During system startup or hot-swapping, the internal control logic releases power to internal backplane rails in a precise timed sequence, preventing voltage sags and protecting sensitive digital microprocessors from destructive inrush currents.
SEQUENTIAL POWER STAGING & NOISE SUPPRESSION:
The 5432-157 integrates multi-stage electromagnetic interference (EMI) filters at the input terminal to block external noise and power surges commonly found in industrial plant power grids. The internal high-frequency switching converter efficiently steps down incoming voltages while providing galvanic isolation between external field supplies and sensitive internal logic circuits.
DIAGNOSTIC MONITORING & REDUNDANCY:
To maximize system uptime on critical turbomachinery, the 5432-157 is built with parallel load-sharing capabilities. When installed alongside a redundant power module in the chassis, diode-isolated outputs allow both units to share the backplane load seamlessly. Front-panel status LEDs provide immediate diagnostic feedback, allowing technicians to verify operational status, input voltage presence, and internal rail integrity at a glance.
