Medical power supplies produce conditioned outputs for medical devices, instruments, and equipment. There are two main types of products: DC power supplies and DC-DC converters. DC power supplies accept alternating current (AC) inputs and provide one or more direct current (DC) outputs. DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems. In terms of features, both DC power supplies and DC-DC converters are often fan-cooled or water-cooled, temperature compensated, and hot swappable. Medical power supplies with a battery backup, computer interface, and integral heat sink are commonly available. Overcurrent protection, overvoltage protection, and power factor correction are important safety considerations.
Medical power supplies that produce DC power differ in terms of technology type and performance specifications. There are three basic technology types: linear, switching, and silicon-controlled rectifier (SCR). Linear power supplies are low-cost, low-noise devices. Medical switching power supplies are highly efficient and provide a higher power density. SCR power supplies provide well-regulated voltage and current outputs. Inputs for medical power supplies use either single-phase or three-phase power; frequencies such as 50, 60, or 400 Hz; and input voltages such as 115, 208, 230, or 480 VAC. Most medical power supplies that produce DC power have multiple voltage outputs. Important specifications to consider include output voltage range, output current range, and DC power.
