Is your industrial power supply completely dead, providing no output voltage at all? ROC Industrial specializes in diagnosing and repairing power supplies that exhibit a complete loss of output. We offer a fast, reliable, and cost-effective alternative to replacement, minimizing downtime and getting your equipment back up and running.
Understanding No Output Voltage in Power Supplies
When a power supply has no output voltage, it means that it is not converting the input AC power into the required DC output voltage. This is a critical failure that will prevent any connected equipment from operating.
Common Causes of No Output Voltage
Blown Fuse: A blown fuse is often the first indication of a problem, and it can be caused by a variety of underlying issues (see below). However, simply replacing the fuse without addressing the root cause will likely result in the fuse blowing again.
Failed Rectifier/Diode Bridge: The rectifier or diode bridge converts AC power to DC power. If it fails, the power supply will not produce any output.
Failed Switching Transistor (MOSFET/IGBT): These transistors are crucial for the switching operation in modern power supplies. A failure here will prevent output.
Transformer Failure: The transformer steps the input voltage up or down. A failed transformer will prevent proper voltage conversion.
Control Circuitry Failure: Problems with the control IC, feedback circuits, or other control components can prevent the power supply from starting or regulating voltage.
Open Circuit: A broken wire, loose connection, or damaged trace on the circuit board can interrupt the power flow.
Input Power Issues: While seemingly obvious, it's important to rule out problems with the incoming AC power (e.g., a tripped circuit breaker, a faulty power cord).
