COSEL AEA1000F power supply – Today’s medical developments

By on November 17, 2021 0

COSEL Co Ltd. announced the introduction of 1000W free air convection cooling power supplies, the AEA1000F series. With demanding applications in mind, the AEA1000F can deliver peak power of 330% for a period of up to 3000 milliseconds. Designed for applications requiring a high level of safety, the AEA1000F is certified according to EN62477-1 (OVC III) for industrial applications and is approved according to ANSI / AAMI ES60601-1 and EN60601-1 3rd edition for medical applications. The AEA1000F is suitable for body flotation (BF) applications and complies with 2MOPP (IN / OUT) and 1MOPP (OUT / FG) safety requirements. The layout of the AEA1000F is optimized for free air convection, making it ideal for use in equipment operating in low noise environments.

With ever increasing levels of automation in industrial and medical applications, power supplies must be able to deliver additional power during peak operating hours, as required by dynamic loads, such as starting the motor. To meet and maintain such conditions, the power supply must be designed with a high level of dynamic control and a power stage capable of withstanding repetitive peak loads. The AEA1000F is capable of delivering 330% of its rated power in free air, convection cooled for a period of up to 3000 milliseconds, which is exceptional and meets the latest market requirements for industrial and medical equipment.

Industrial applications now require efficient power supplies that can operate in various environments with a high level of safety. The AEA1000F is certified to EN62477-1 overvoltage category three (OVC III), which means that final equipment powered by the products can be directly connected to the main distribution panel without adding an isolation level. additional. This simplifies the task of the system designer, reduces costs and guarantees the highest level of efficiency.

For medical applications, AEA1000F input-output insulation conforms to 2MOPP, its input to ground to 1MOPP and its output to ground to 1MOPP, which makes the product suitable for body float (BF) applications. The units are approved in accordance with ANSI / AAMI ES60601-1 and EN60601-1 3rd Edition.

The AEA1000F has 4000 VAC input-output isolation, 2000 VAC input to ground (FG) and 1500 VAC output to ground (FG).

Designed for international applications, the versatile AEA1000F has an input voltage of 85VAC to 264VAC. Three output voltages are available: 24 V, 36 V and 48 V with respective rated currents of 42 A, 28 A and 21 A. The output voltage can be adjusted using a built-in potentiometer.

For low harmonic current distortion, the AEA1000F uses an active power factor corrector (PFC) and the switching stage uses an LLC resonant topology deploying the latest generation of power semiconductors, providing typical efficiency up to ‘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, the “Slaves” automatically and carefully adjust their output voltage to be of equal value.

Optimized for convection cooling, the AEA1000F can operate in an ambient temperature range of -20 ° C to +70 ° C. Depending on the method of assembly and ventilation used in the final equipment, derating may apply as specified in the technical documentation.

The AEA1000F includes built-in inrush, overcurrent, overvoltage and thermal protection circuitry.

In its open frame format, the AEA1000F measures 50mm x 127mm x 228.6mm (1.97 “x 5” x 9 “) and weighs 1.5kg max.

The AEA1000F meets the safety requirements: UL (United States), C-UL (Canada), DEMKO (Denmark) and TUV (Germany). The product is UL62368-1, EN62368-1, EN62477-1 (OVC III) certified.

To meet the specific requirements of the application, a number of options are available, in particular: coating (C), additional cover (N), screw positioned vertically on a terminal block (T), terminal block transformed into a connector (J), extended functions: auxiliary outputs (AUX1 12V1A), (AUX2 5V1A), on / off and remote alarm (R3), UL508 certification (T5), overcurrent protection mode changed from hiccup mode to shutdown (P5).

The AEA series is suitable for a wide range of applications such as: robots and robotics, infusion pumps, fans, actuators, process control, radio and transmission equipment and emergency signaling.

The AEA1000F series has a full five-year warranty and is compliant with European RoHS, REACH and low voltage directives.
