This Product Selection Guide contains information to help select products in the AC/DC Configurable Power Supply Chassis category on DigiKey.com
Configurable AC/DC Power Supply Chassis products are the outermost component of a user-configurable power supply system. Such systems are modular in nature, allowing rapid construction of semi-custom power conversion products by the insertion of output-specific conversion modules into an outer chassis that provides mechanical containment and typically a number of electrical factors that are common/shared among the conversion modules, such as rectification and power factor correction. Product series represented in this family are user-configurable and do not require specialized tools or training for assembly.
SelectionCharacteristics
Specifications to determine which AC/DC configurable power supply chassis is right for your application.
Type: The type of equipment or environment the device will be used in, they are tested and typically rated by a third party to ensure certain minimum standards for the application they are intended for. You could use one with a higher rating, but you cannot use one with a lower rating as it will fail in that application. For example, you could use a medically rated device to replace a commercial device, but you cannot replace the medical device with the commercial device.
Available Types
High Reliability, COTS (Commercial Off The Shelf)
Meets the reliability and environmental requirements for the military electronics industry. Ideal for radar, communications, testing, measurement, and data acquisition applications.
High Temperature
Designed for use in applications with high ambient temperatures.
Medical
Designed to meet the standards for use in medical applications.
Medical, Low Noise
Designed to meet the standards for use in medical applications but produces less acoustic noise.
Medical, Ultraquiet
Designed to meet the standards for use in medical applications but produces the least amount of acoustic noise.
Standard
Designed for use in typical environments, such as industrial equipment, printing, automation equipment, telecommunications, testing, and measurement.
Standard, Low Noise
Designed for use in typical environments but produces less acoustic noise.
Standard, Ultraquiet
Designed for use in typical environments, but produces the least amount of acoustic noise.
Number of Positions: How many slots it has for power modules to be inserted.
Voltage - Input: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Power (Watts): Maximum amount of power the device can provide - due to losses you generally want your applications power needs to be between 40%-60% of what your power supply can provide.
Voltage-Isolation: Maximum voltage the device can withstand for one second and still maintain electrical isolation.
Efficiency: Ratio of output power to input power, typically measured at nominal voltage under full load.
Features: These are different capabilities of the power supply such as conformal coating, temperature alarm, remote sense, etc.
Available Features
Conformal Coating
All the components and circuity are coated in a protective layer.
Fan Fail
Signal indicating that at least one of the fans in the power supply is failing to operate.
Reverse Fan
Has reverse air flow, ideal for dispelling air from the system.
Remote Sense
Uses extra sensing wires to detect voltage drop from the cables and compensate for it at the output.
Ruggedized
Designed for applications subject to shock or vibration.
Temperature Alarm
Signal indicating excessive temperature has been reached. This could be due to environmental factors or fan failure. Typically tripping this alarm will shut down the system.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Size/Dimensions: The physical dimensions of the device, typically, length and width.
Height: The height of the device.
Approval Agency: Meets the minimum safety standards of the approving agency. These agencies are either government entities or private third-party labs that protect consumer safety.
