Power Supply Repair Services

What Happens When a Power Supply Goes Down?

What happens when your power supply goes out? Simply put, your machines and devices won’t receive the go-go juice they need to be able to keep humming! When an industrial power supply stops working correctly, a company like yours has to deal with downtime, lost production, frustrated clients, and lost revenue. Ain’t nobody got time for that! AES is here to deliver efficient, effective repair services for your industrial power supply, and we’re always here when you need us!

A Better Understanding of Power Supplies

A power supply unit typically converts electrical power to the frequency, current, and voltage needed for specific applications, often involving AC/DC conversions. There are also power supplies that convert other forms of energy, including solar power or mechanical energy. Here are some common power supplies found in industrial settings:

• Variable AC Power Supply: A variable power supply allows you to change the output voltage and – in some cases – current. Variable AC power supplies make use of specialized transformers to change the AC-to-AC voltage and current while leaving the power source frequency unchanged.

• Frequency Changing: Whenever you need to alter the frequency of AC power, a frequency changer is the preferred power supply. These types of power supplies often make use of motor-generator sets or rectifier-inverter sets. With a rectifier-inverter, AC is changed to DC and then changed back to AC with whatever specific frequency is needed.

• Isolation Transformers: Isolation transformers serve to transfer electricity from an AC source to a connected device or piece while also keeping the powered device isolated from the power source. These are helpful when impedance matching is needed, and they also allow for the most efficient transfer of power between stages.

• Unregulated Linear Power Supply: An unregulated linear power supply offers a simple AC-to-DC conversion. This type of power supply is typically comprised of a step-down transformer, rectifier, filter capacitor, and bleeding resistor. Two of the key benefits of an unregulated linear power supply revolve around its durability and simplicity. The downside of this particular application is that it’s only designed for the output of a single voltage and current.

• Linear Regulated Power Supply: Linear regulated power supplies also convert AC to DC. They function similarly to unregulated power supplies, with this distinction – they utilize a transistor circuit rather than a bleeding resistor. This regulator circuit enables the supply to convert the main AC voltage into a more stable DC voltage, which is really ideal for devices that depend upon a steady, consistent power supply. These types of power supplies also happen to be more expensive and less energy-efficient than unregulated linear supplies.

• Switching Regulated Power Supply: Also known as switch mode power supplies (SMPS), switching regulated power supplies are available in AC-to-DC or DC-to-DC configurations. They use a complicated, high-frequency switching method with pulse width modulation and feedback to regulate output. Switching power supplies have the advantage of being more efficient than linear supplies; one negative is that they also produce a significant level of audible noise.

• Ripple Regulated Power Supply: This type of power supply is another update to unregulated linear supplies. It’s based on an unregulated power supply, but uses a transistor circuit in the saturation region, which maintains the desired voltage by transferring DC power to a capacitor. A ripple regulated power supply is also more efficient in comparison to an unregulated supply.

• Adjustable Regulated Power Supplies: An adjustable regulated power supply allows the user to adjust output voltage on a continuous basis. These power supplies are based on a linear regulated supply, but also add a variable resistor. This resistor allows the power supply to provide voltages from zero all the way up to whatever maximum amount is allowed.

• Battery and Solar Power Supplies: Solar panels and batteries can offer a reliable supply of DC power, but that power must be filtered to ensure that no pulsating ripples remain. After the filtration process, voltage regulator ICs can then adjust the energy supply to the required voltage level for specific applications. Should a user need to step up the voltage, transistors can also be added to the circuit.

• DC-to-DC Converters: If all that is required is a step-up or step-down of DC voltage, then a DC-to-DC converter is the way to go. These power supplies come in electrochemical, electromechanical, and semiconductor designs. The semiconductor converter is the most common, and includes varieties like push-pull, buck, boost, and buck-boost types. A DC-to-DC converter allows the user to create various levels of DC from a single supply, rather than requiring multiple AC-to-DC supplies to power the same device.

• DC-to-AC Power Supplies: DC-to-AC supplies are also simply known as power inverters. Since DC power typically offers a lower voltage than is needed for powering AC devices, DC-to-AC power supplies are often used as backups in the event of power failure. These supplies can take the energy that’s stored in a battery or cell and convert it to an AC voltage appropriate for the needs of the device in question.

The AES Power Supply Repair Process

At AES, our team is trained and experienced in repairing nearly any type of essential equipment for industrial or commercial applications. We’re more than capable of handling your power supply repair needs, too! Our proven electronics repair process is both effective and efficient. Here’s how we approach every repair:

Receipt, Evaluation, & Quote Generation

Once you send your equipment to AES, we provide a FREE initial evaluation & quote for every potential repair service. We’ll take the time to diagnose the issues with your equipment, then we’ll communicate exactly what your repair solution will involve. We work to get a repair quote out to you within 48 hours of item receipt.

Repairs, Testing, & Retesting

Once you approve the repair order, we’ll put it on our schedule and then get right to work! We’ll troubleshoot your power source, including testing it under load conditions, and then we’ll provide any needed repairs.

Our job isn’t done yet, though. We follow up by testing and retesting your equipment under realistic, full-load conditions. That way, we can ensure that your equipment will truly be ready to go when you receive it back at your facility!

Cleaning & Final Preparations

Some electronics repair groups are satisfied that their job is done once the actual repairs are completed – but that’s not the AES way. We also recognize that we’re dealing with sensitive electronic equipment, which will perform for you much smoother (and much longer) if it’s also properly cleaned. Our cleaning process is thorough, including the removal of any oil, contaminants, and residual moisture.

Quality Assurance Measures & Return Shipping

Before we sign off on your equipment, we’ll conduct a final round of quality assurance measures. Once those are completed, we’ll then carefully prepare your equipment for return shipping, including using the right packaging to suit the size, shape, and weight of your particular item or component.
