AC-DC Power Supply Units

Q: What is an AC-DC power supply?

An AC-DC power supply is a device that converts alternating current (AC) to direct current (DC) to provide electrical energy to a load. These power supplies are used in various applications, including medical and industrial settings. They come in several forms, such as open frame, enclosed, and configurable power supplies, each offering different protections and regulatory approvals.

Q: What types of AC-DC power supply units does Advanced Energy offer?

Advanced Energy offers configurable/modular, open frame, enclosed frame, capacitor chargers, PCB mount, and custom or modified standard power supplies with various cooling systems. These units range from 200W to 24,000W, catering to multiple applications.

Q: Who should use Advanced Energy's AC-DC power supplies?

Advanced Energy's AC-DC power supplies are ideal for low-voltage applications that require converting AC power to DC power. Designed and approved for medical and industrial use, these power supplies are perfect for applications needing highly efficient conversion and precise switching capabilities, particularly in the medical and industrial sectors.

Q: What should I consider when selecting an AC-DC Power Supply Unit (PSU)?

Key factors include input AC voltage and output DC voltages, which dictate the PSU's requirements. Input AC voltage typically ranges from 85 to 264 Vac globally, depending on the region. Standard DC output voltages include 5, 12, 24, and 48 Vdc. The most critical factor is the output power or load current, which must align with the PSU's output power. Additional considerations include operating temperatures, cooling mechanisms, efficiency, packaging and mounting styles, and compliance with operational and safety regulations. Warranty, customer service, and technical support are essential for selecting an AC-DC PSU.

Q: How do I select the right AC-DC Power Supply Unit for my needs?

Start by determining your device's input DC voltage, power requirements, and AC voltage. Then, look for power supply units that meet these input and output specifications. Your PSU should also align with your mechanical requirements, such as size, and meet performance criteria like power density and efficiency. Always select a power supply compatible with your device, has the necessary safety regulatory approvals, and is backed by a company that offers a warranty and long-term technical support.

Q: Does Advanced Energy offer AC-DC PSUs for Medical Applications?

Yes, Advanced Energy provides a wide range of medical-grade AC-DC power supplies. These units are rigorously tested in-house to meet all safety and operating standards and have received FDA and other regulatory approvals. Advanced Energy’s AC-DC PSUs are used in various medical applications, including medical imaging, life sciences, electrosurgery, medical lasers, patient care, and surgical robotics. Additionally, AE offers customized AC-DC power supply solutions if standard units don’t meet your requirements.

Q: Does Advanced Energy offer custom AC-DC power supplies?

Yes, Advanced Energy offers a wide range of standard and configurable AC-DC power supplies that can meet most application needs. If these options don't fit your requirements, AE can customize AC-DC power supplies. This includes electrical, mechanical, and firmware customization, all tailored to your application and compliant with regulatory standards. Advanced Energy's engineers will work closely with your team to design AC-DC power supplies that perfectly fit your products.

Q: Do PSUs go bad over time?

Any power supply unit's performance can decline over time due to high operating temperatures, improper handling, component burnout, and output overloads. The extent of this decline depends on the PSU's quality and how it’s used. Proper maintenance, careful handling, and avoiding overloads can extend a PSU's lifespan. Advanced Energy offers high-quality, reliable PSUs with warranties of up to five years, depending on the product.

Q: What certifications do Advanced Energy’s power supplies meet?

Advanced Energy’s power supply units are either medically or industrially graded and meet the base standard of IEC 60601. Beyond this, Advanced Energy’s products also comply with specific standards addressing parameters like electromagnetic compatibility, radiation protection, protection class, and ROHS, ensuring they meet a wide range of customer requirements.

Q: Where can I find technical documentation for your AC-DC power supply units?

Advanced Energy provides comprehensive technical documentation through our e-commerce website. To find the documentation you need, search for the specific product, open its page, and scroll down to the technical documentation section. You can access datasheets, installation instructions, PMBus communication details, user manuals, and more there.
