About AC to AC Voltage Transformers
For single-phase equipment, use this formula to find power output: VA = Volts × Amps
For three-phase equipment, use this formula to find power output: VA = Volts × Amps × 1.73

EMI-Filtering IEC Connectors with Integrated Power Supply
Change AC voltage to DC voltage and bring power to electronic devices while protecting them from harmful electromagnetic interference (EMI). Even with their built-in power supply, these connectors have the same overall footprint as those without a power supply. All are for use with standard IEC power cords. Commonly used to convey power from wall outlets, you won’t have to wire your devices to an external power source. Instead, wire these connectors into your device with the terminals on the back of each connector.
For fast wire connections, these connectors have quick-disconnect terminals. The terminals slide together with the quick-disconnect terminals on your wiring and are easily disconnected by hand, but still provide a strong hold.
All of these connectors use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot. If you exceed the maximum voltage or load, the connectors will shut down to protect both the power supply and the connected device. They also meet the voltage requirements for use in a SELV (separated extra low voltage) circuit.
These connectors meet U.S. and international standards for safety. They also meet UL 94V0, which means they self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping. All have Class I shock protection—they're insulated and have a protective ground to prevent electrical shocks.
Maximum output noise is also known as ripple noise. When power supplies convert AC voltage to DC voltage, some noise from the AC voltage will carry into the output. While this noise won't affect most applications, it can interfere with other signals in extremely sensitive audio equipment and high-precision measuring and testing equipment. The lower the output noise, the less interference it creates.
Power factor and efficiency give you a sense for how efficiently these connectors draw AC power and convert it into DC power, which ultimately affects your operating cost. The closer the power factor is to 1, and the higher the efficiency percentage, the lower the operating cost. The more efficient the power supply, the cooler it runs.
