Section		1:	Introduction
The	JPS250	Series	Switching Power Supply is a single output switcher
that	utilizes	Zero	Voltage / Zero Current topology to allow efficient

operation, small size and quite operation. The Supplies offer 250 watt

operation with			18 cfm airflow and 200 watt convection cooled operation.
Features		Include:
§	Ideal	for	1U	High	/ Low Profile	Applications
§	Active Power			Factor	Correction for	EN61000-3-2 Compliance

§Greater than 80% Efficiencies

§World-Wide Safety Approvals

§Class B Emissions

§Full Featured Control and Status Signals
