Cosel's 800W free air convection cooled AEA800F series power supplies. Considering the requirements of some demanding applications, AEA800F is able to deliver 300% peak power for as long as 3000ms. Designed for applications requiring high safety, it has passed EN62477-1 (OVC III) standard certification for industrial applications, and has obtained medical certification for ANSI/AAMI ES60601-1 and third edition EN60601-1. AEA800F is suitable for medical buoy (BF) and complies with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety isolation requirements. Some layout optimizations have been made for free air convection cooling, making it ideal for use in equipment operating in low-noise environments.

  • Provides 300% peak power within 3000ms
  • N62477-1 OVC III Safety Certified for Industrial Applications
  • Suitable for medical float (BF) applications
  • Optimized PCB layout for free air convection cooling, small and compact
  • High efficiency, low energy consumption
  • 5 years warranty

With the increasing level of automation in industrial and medical applications, power supplies must be able to provide additional power during full-load operation time according to dynamic loads (such as motor starting). To meet and maintain this state, the power supply must be designed with a high level of dynamic control and a power stage capable of withstanding multiple full loads. In a free air convection cooling environment, AEA800F can provide 300% peak power for as long as 3000ms, which can perfectly respond to the latest industrial and medical equipment market demands.

Today, industrial applications require power supplies that are efficient and able to operate with high safety in various environments. AEA800F has passed the EN62477-1 category three overvoltage (OVC III) certification, which means that the final equipment powered by this product can be directly connected to the main switchboard without adding additional isolation. This simplifies the work difficulty of the system designer, reduces the cost and ensures the efficiency.

For medical applications, the AEA800F has an isolation of 2MOPP input to output, 1MOPP input to ground, and 1MOPP output to ground, making it suitable for floating body (BF) applications. This product has passed ANSI/AAMI ES60601-1 and third edition EN60601-1 certification.

AEA800F has insulation voltage levels of 4000VAC input to output, 2000VAC input to ground (FG) and 1500VAC output to ground (FG).

The input voltage of AEA800F is 85-264VAC, which is suitable for worldwide use. It provides three output voltages: 24V, 36V and 48V, and the output rated current is 34A (72.5A peak), 22.7A (48.4A peak) and 17A (36.3A peak), and you can also use the built-in potentiometer to adjust the output voltage yourself .

For the problem of low harmonic current distortion, AEA800F adopts active power factor corrector (PFC) and adopts the latest generation of power semiconductor LLC resonant topology in the switching section to deal with the current distortion problem, and the classic efficiency is as high as 95%.

AEA800F can obtain more power through parallel connection, up to six units can be used in parallel. When used in parallel, the output voltage can be adjusted by the "Master" unit, and the "Slaves" will automatically and neatly adjust their output voltages to equal values.

The AEA800F is optimized for convection cooling, allowing it to work in ambient temperatures from -20 to +70 degrees Celsius. Depending on the assembly method and ventilation used in the final device, the power supply may be derated according to the technical documentation.

AEA800F comes with surge current, overcurrent, overvoltage and thermal protection circuits.

The dimensions of the AEA800F open frame are 50x127x203.2mm (1.97x5x8 inches), and the maximum weight with the cover is 1.4kg.

The safety requirements that AEA800F meets are: UL (USA), C-UL (Canada), DEMKO (Denmark) and TUV (Germany). The product has passed UL62368-1, EN62368-1, EN62477-1 (OVC Ⅲ) certification.

To meet the needs of specific applications, a variety of options are available including: coating (C), additional cover (N), vertical set screw on terminal block (T), junction box to connector (J). The extended functions are: auxiliary output (AUX1 12V1A), (AUX2 5VA1), remote ON/OFF and alarm (R3), UL508 certification (T5), overcurrent protection mode changed from hiccup mode to shutdown (P5).

The AEA series is suitable for a variety of applications such as: robotics and robotics, infusion pumps, ventilators, actuators, process control, radio and transmission equipment and emergency signaling devices.

The AEA800F series has a shelf life of 5 years and complies with European RoHS, REACH and low voltage directives.

The AEA series includes three models, AEA600F, AEA800F and AEA1000F, all of which can provide peak power for equipment with harsh application environments.
