The 5417-168 is a High Voltage Power Supply (HVPS) Module designed and manufactured by Woodward for MicroNet and NetCon digital governor and turbine control chassis. Acting as a core power conditioning node, this module accepts high-voltage AC or DC plant supply feeds and converts them into stabilized, low-noise internal DC power rails. It ensures uninterrupted power delivery to CPU processors, memory modules, and field transceiver cards installed across the main control backplane.
HIGH-EFFICIENCY SWITCHING FRONT-END & NOISE SUPPRESSION:
Incoming high-voltage power passes through an internal electromagnetic interference (EMI) filtering network designed to strip out high-frequency transients, surges, and electrical noise common to power generation plants. The input stage utilizes a high-frequency switching power topology to maintain consistent regulation across varying load demands. Built-in hold-up capacitors ensure that minor voltage sags or momentary line interruptions do not cause system microprocessors to reset.
DUAL REDUNDANCY & DIAGNOSTIC MONITORING:
The 5417-168 module supports parallel redundant operation within multi-power-supply chassis configurations. Diode-isolated outputs allow two power supply modules to share the rack's total electrical load. If one supply or its feeding power line fails, the secondary supply seamlessly carries the full operational load without interruption. Onboard monitoring logic continuously tracks output voltage levels and illuminates front-panel diagnostic LEDs to alert operators immediately to power rail degradation or overvoltage faults.

What is Woodward 5417-168?
The 5417-168 is a High Voltage Power Supply (HVPS) module engineered by Woodward for MicroNet and NetCon digital control systems. Mounted directly into the chassis power slot, it converts high-voltage AC or DC utility power into regulated low-voltage DC rails required to power internal processing electronics and communication modules.
What types of power feeds can be connected to the High Voltage Power Supply Module?
The 5417-168 handles high-voltage inputs, accepting either nominal 88–132 VAC (47–63 Hz) or 90–150 VDC power lines, making it suitable for standard power station auxiliary supplies and station battery banks.
How does the High Voltage Power Supply Module handle module failure in a redundant system?
In a chassis configured with dual power supply slots, two modules operate in parallel with output isolation diodes. If one module experiences a fault or loses its supply feed, the remaining module instantly absorbs the entire system load without dropping the backplane voltage or triggering a controller reset.
What on-site steps verify if a system fault is caused by the 5417-168 module or an external backplane short?
If the input LED is lit green but the DC Output LED is unlit or red, turn off power, remove all downstream I/O modules, and re-energize the supply. If output voltage returns to normal, a field short-circuit or failed I/O board is pulling down the DC rail; if the supply remains faulted with no load attached, the internal switching circuitry of the 5417-168 has failed.
