Cosel has launched a 1kW free-air convection cooled AC-DC power supply series for medical and industrial applications
The AEA1000F can deliver 330 percent peak power for a period of up to 3s and the layout is optimized for free-air convection making it ideal for use in equipment being operated in low noise environments. This includes robots and robotics, infusion-pumps, ventilators, actuators, process control, radio and transmission equipment, and emergency signaling.
The family has an input voltage of 85 to 264VAC with three output voltages: 24V, 36V and 48V with respective current ratings of 42A, 28A and 21A. Output voltage can be adjusted using a built-in potentiometer.
The family is certified to the EN62477-1 (OVC III) standard for industrial applications and is approved in accordance with ANSI/AAMI ES60601-1, and EN60601-1 3rd Edition for medical applications.
The AEA1000F is also suitable for Body Floating (BF) applications and complies with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety requirement. The input to output isolation is 4,000VAC, input to ground (FG) is 2,000VAC and output to ground (FG) is 1,500VAC.
To satisfy and sustain the demand for extra power during peak operation times as required by dynamic loads such as motor startup, the supply must be designed with a high dynamic control level and a power stage able to sustain repetitive peak loads.
Industrial applications are now requiring efficient power supplies that are able to work in various environments with a high level of safety. The EN62477-1 certification allows the final equipment powered by the products to be directly connected to the main distribution panel without adding an extra level of isolation. This simplifies the systems designer’s task, reduces costs and guarantees the highest level of efficiency.
For medical applications, the AEA1000F input to output isolation complies with 2MOPP, its input to ground with 1MOPP, and output to ground with 1MOPP making the product suitable for Body Floating (BF) applications. The units are approved in accordance with ANSI/AAMI ES60601-1 and EN60601-1 3rd Edition.
For low harmonic current distortion, the AEA1000F uses active Power Factor Corrector (PFC), and the switching stage uses an LLC resonant topology deploying the latest generation of power semiconductors, conferring to a typical efficiency of up to 95%.
For additional power the AEA1000F can be connected in parallel, up to six units. When in parallel, by adjusting the output voltage on the ‘Master’ unit, ‘Slaves’ neatly automatically adjust their output voltage to be of equal value.
Optimized for convection cooling, the AEA1000F can be operated within an ambient temperature range of -20 to +70 degree centigrade. Depending on the assembly method and ventilation used in the final equipment, a derating may apply as specified in the technical documentation.
The AEA1000F includes built-in inrush current, overcurrent, overvoltage protection circuits, and thermal protection and in its open frame format measures 50 x 127 x 228.6mm (1.97 x 5 x 9 inches) and weighs 1.5kg max.
Options include Coating (C), Additional cover (N), Vertical positioned screw on a terminal block (T), Terminal block changed to a connector (J), Extended features: Auxiliary outputs (AUX1 12V1A), (AUX2 5V1A), Remote ON/OFF and Alarm (R3), UL508 certification (T5), Over current protection mode changed from hiccup mode to shutdown (P5).
The AEA1000F series has a full five-year warranty and conforms to the European RoHS, REACH and Low Voltage Directives.
