COSEL adds 800W device to AEA series of power supplies

2 mins read

COSEL has introduced 800W free-air convection cooling power supplies, the AEA800F series.

Designed for demanding applications, the AEA800F is able to deliver 300% peak power for a period of up to 3,000 milliseconds and 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 AEA800F is suitable for Body Floating (BF) applications and complies with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety requirement.

The AEA800F layout is optimised for free-air convection making it suitable for use in equipment being operated in low noise environments.

The AEA800F 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 AEA800F has an input voltage of 85 to 264VAC. Three output voltages are available: 24V, 36V and 48V with respective current ratings of 34A (Peak 72.5), 22.7A (Peak 48.4A) and 17A (Peak 36.3A). Output voltage can be adjusted using a built-in potentiometer.

For low harmonic current distortion, the AEA800F 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 AEA800F 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 AEA800F can be operated within an ambient temperature range of -20 to +70C. Depending on the assembly method and ventilation used in the final equipment, a derating may apply as specified in the technical documentation.

The AEA800F includes built-in inrush current, overcurrent, overvoltage protection circuits, and thermal protection.

In its open frame format, the AEA800F measures 50 x 127 x 203.2 mm (1.97 x 5 x 8 inches) and weighs 1.4kg max with cover.

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 AEA800F series has a full five-year warranty and conforms to the European RoHS, REACH and Low Voltage Directives.

The AEA series includes three models covering from 600W to 1000W, the AEA600F, AEA800F, AEA1000F all offering peak power for demanding applications.
