300% peak power open-frame power supplies for medical and industrial applications
07 July 2021
COSEL Co, Ltd announced the introduction of 600W free-air convection cooling power supplies, the AEA600F series.
With demanding applications in mind, the AEA600F is able to deliver 300% peak power for a period of up to 1,000 milliseconds. Designed for applications requiring a high level of safety, the AEA600F 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 AEA600F is suitable for Body Floating (BF) applications and complies with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety requirement. The AEA600F 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 e.g., motor start-up. 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 AEA600F is able to deliver 300% of its free-air, convection cooled, nominal power during a period of up to 1,000 milliseconds, which is outstanding and responds to the latest market requirements from industrial and medical equipment.
Industrial applications are now requiring efficient power supplies that are able to work in various environments with a high level of safety. The AEA600F 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 AEA600F 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 AEA600F has an input to output isolation of 4,000VAC, input to ground (FG) of 2,000VAC and output to ground (FG) of 1,500VAC.
Designed for international applications, the versatile AEA600F has an input voltage of 85 to 264VAC. Three output voltages are available: 24V, 36V and 48V with respective current ratings of 25A, 16.7A and 12.5A. Output voltage can be adjusted using a built-in potentiometer.
For low harmonic current distortion, the AEA600F 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 AEA600F 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.
Optimised for convection cooling, the AEA600F can be operated within an ambient temperature range of -20 to +70ºC. Depending on the assembly method and ventilation used in the final equipment, a derating may apply as specified in the technical documentation.
The AEA600F includes built-in inrush current, overcurrent, overvoltage protection circuits, and thermal protection.
In its open frame format, the AEA600F measures 41 x 127 x 186mm (1.61 x 5 x 7.32 inches) and weighs 1kg max.
The AEA600F 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 signalling.
The AEA600F series has a full five-year warranty and conforms to the European RoHS, REACH and Low Voltage Directives.
