AC Power Sources Specifications

AC Output


	Phase
	Your choices are...
	Single-Phase		The AC output is single-phase; the more commonly used AC type. Single-phase is often but not exclusively used for lower voltage applications.
	Three-Phase		The AC output is three-phase. Three-phase inputs are typically used for high voltage power supplies.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	AC Output Voltage		Enter the AC output voltage.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Output Frequency
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	AC Output Current
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Apparent Power		Apparent power is the product of the root mean square (RMS) current and the RMS voltage of the AC output. This amount is the same as the VA rating.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Number of Outputs		Enter the number of outputs.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Adjustable Voltage?		Enter the adjustable voltage for the output.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Adjustable Frequency?		Enter the adjustable frequency for the output.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Integral Heatsink		Devices have an integral heatsink for cooling.
	Overcurrent Protection		Overcurrent protection is internal circuitry that limits or shuts down the current output during overcurrent conditions.
	Overvoltage Protection		Overvoltage protection is internal circuitry that limits or shuts down the voltage output during overvoltage conditions. Typically, overvoltage protection is provided for the primary output.
	Power Factor Correction		Power factor correction is used to correct the phase difference between voltage and current in order to optimize power output.
	Pure Sine Output		Pure sine output produces a very high quality, pure sine waveform output.
	Remote On / Off Switch		Devices can be turned on and off remotely.
	Short Circuit Protection		Short circuit protection may include electronic current limiting and thermal resets with automatic recovery.
	Temperature Compensated		Devices compensate for changes in temperature that can result in undesirable outputs.
	Water Cooled		Devices are water-cooled for temperature stability.
	Weatherproof		Weatherproof devices can withstand prolonged exposure to outdoor conditions such as rain or snow.
	Other		Other unlisted features.
