Cosel has announced the introduction of 1000 W free-air convection cooling power supplies, the AEA100OF series. With demanding applications in mind, the AEA100OF is able to deliver 330 % peak power for a period of up to 3,000 milliseconds. Designed for applications requiring a high level of safety, the AEA100OF is certified according 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 AEA100OF is suitable for Body Floating (BF) applications and complies with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety requirement. The AEA1000F layout is optimized for free-air convection making it ideal for use in equipment being operated in low noise environments.

With the ever increasing levels of automation in industrial and medical applications, power supplies must be able to deliver extra power during peak operation times as required by dynamic loads, eg: motor startup. To satisfy and sustain such conditions the power supply must be designed with a high dynamic control level and a power stage able to sustain repetitive peak loads.

The AEA100OF is able to deliver 330 % of its free-air, convection cooled, nominal power during a period of up to 3000 milliseconds, which is outstanding and responds to the latest market requirements from industrial and medical equipments.

Industrial applications are now requiring efficient power supplies that are able to work in various environments with a high level of safety. The AEA100OF is certified to the EN62477-1 Over Voltage Category Three (OVC III), meaning that a final equipment powered by the products can 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 AEA100OF 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.

The AEA100OF has an input to output isolation of 4000 VAC, input to ground (FG) of 2000 VAC and output to ground (FG) of 1500 VAC. Designed for international applications, the versatile AEA1000F has an input voltage of 85 to 264 VAC. Three output voltages are available: 24 V, 36 V and 48 V with respective current ratings of 42 A, 28 A and 21 A. Output voltage can be adjusted using a built-in potentiometer.

For low harmonic current distortion, the AEA100OF 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 AEA100OF 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 AEA100OF includes built-in inrush current, overcurrent, overvoltage protection circuits, and thermal protection. In its open frame format, the AEA1000F measures 50 x 127 x 228.6 mm (1.97 x 5 x 9 inches) and weighs 1.5 kg max.

The AEA100OF complies with safety requirements: UL (USA), C-UL (Canada), DEMKO (Denmark), and TUV (Germany). The product is UL62368-1, EN62368-1, EN62477-1 (OVC III) certified. To accommodate application specific requirements, a number of options are available including: 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 AEA series is suitable for a large range of applications such as: robots and robotics, infusion-pumps, ventilators, actuators, process control, radio and transmission equipment, and emergency signaling. The AEA1000F series has a full five-year warranty and conforms to the European RoHS, REACH and Low Voltage Directives. Designed for industrial and medical applications, Cosel’s AEA100OF delivers 330% peak power up to 3,000 milliseconds.
