mA Power Converters can refer to two different things: a device that converts a current in milliamperes (mA) to another current signal (e.g., a 0-200 mA to 4-20 mA converter) for industrial control systems, or it can refer to an AC-DC power adapter with a current rating listed in mA (e.g., a 500 mA adapter) used to power electronic devices. The term “mA” indicates the current (amperage) the device handles or outputs.
