Diagnostic report for a Hantle 1700W power supply emitting a burning smell in a commercial kiosk, including troubleshooting steps and safety warnings.
Acceptable voltage range should be 23VDC - 25VDC.
Every 3 months is recommended in a high-traffic environment.
Yes, a higher wattage power supply can be used, however, it is unnecessary as the system does not need the extra amperage.
The Hantle 1700W power supply provides 24V DC to the bill validator, solenoids, and logic circuits within the kiosk. Internal components such as capacitors, transformers, and rectifiers convert the AC input voltage to the required DC voltage. Over time, heat and electrical stress degrade these components, leading to reduced efficiency and eventual failure. The burning smell indicates overheating, likely due to insulation breakdown or component failure.
Power supply emitting a burning smell. Unit suspected to be nearing complete failure.
The Hantle 1700W power supply operates at potentially lethal voltages. Do not attempt to repair the power supply yourself. Always disconnect the power supply from the AC power source before performing any inspection or maintenance. Ensure proper grounding to prevent electrical shock. Only qualified technicians should handle power supply replacement. Avoid contact with internal components.
Regularly inspect the power supply for dust and debris accumulation. Use compressed air to clean the unit as needed.,Ensure that the kiosk is located in a well-ventilated area to prevent overheating.,Periodically check the input and output voltage of the power supply to identify any signs of degradation.,Implement surge protection to protect the power supply from voltage spikes and surges.,Replace the power supply every 3-5 years, or as recommended by the manufacturer, to prevent failures due to component aging.,Ensure proper cable management to prevent strain on power connectors.
Before replacing the power supply, check the DC voltage at the bill validator connector. A low voltage reading, even with a functional power supply, can indicate a short circuit in the validator itself, causing the power supply to work harder and potentially overheat. Replacing the validator along with the power supply may be necessary.
