In the top schematic, these protection elements feed into a latch that simultaneously drives the low and turns off all gate drivers.

Once the main switching transistors (driven by the PWM controller) oscillate current through the main transformer, the secondary stage steps the voltage down to standard PC requirements:

Synchronous rectification systems and heavy-duty diodes transform the high-frequency AC into stable, low-voltage outputs. ps42419ha schematic top

For further exploration, refer to the and relevant HP service manuals for the specific desktop model you are working on. Always prioritize safety when handling internal PSU components, and consider using an adapter board if replacing the original PSU with a standard ATX unit.

Rectify the low-voltage AC to DC.

Calculating the required values for overcurrent protection.

PS-4241-9HA is a 240W desktop power supply unit (PSU) manufactured by In the top schematic, these protection elements feed

: Implements an active boost topology that aligns input current with voltage phases. This configuration achieves an exceptional 0.99 Power Factor (PF) under full load, minimizing wasted reactive power.

The part number (often associated with the manufacturer Pulse Electronics ) typically refers to a Quad Port Gigabit Ethernet Magnetic Module (RJ45 magnetics). PS-4241-9HA is a 240W desktop power supply unit
