Cosel has launched a 1U configurable power supply range for medical applications.

The AME series has four models, AME400F, AME600F, AME800F and the AME1200F, covering applications from 400W to 1200W. These are designed with 2MOPP I/O isolation for medical designs.

Each version can host independent output modules that can be combined and mixed to offer a custom configuration for the application. To perfectly optimize configuration to customers’ requirements, two versions of output modules are offered, 120W and 240W. Both modules are available in four output voltages, +5V, +12V, +24V and +48V.

Each AME module performs as a standalone power unit, and control and monitoring functions can be accessed via a single connector. The 240W module includes ON/OFF remote control, alarm signals, voltage sensing, output voltage and current control. Output voltage can be adjusted by using the built-in potentiometer or an external voltage. When using external voltage control, the output voltage can be trimmed down to almost zero volts. By using the current trimming function (ITRM) the module can operate as a constant current source. Also, by combining voltage and current control (VTRM and ITRM) it simply works as a constant voltage / constant current (CVCC) generator.

With 24V and 48V outputs and equipped with the 240W module the AME series has a built-in peak current capability suitable for medical applications such as laser or pulse generator duties. Thanks to COSEL technology, higher voltages can be achieved by connecting modules in series, and for greater total power they can also be connected in parallel.

Designed for less demanding control applications, the 120W interface is limited to remote ON/OFF and alarm. All modules include over-voltage and over-current protection with automatic recovery.

As standard, power output connectors are screw terminals, though certain applications may require isolated terminations or quick connect types. For these, a Molex connector is provided instead of the terminal block.

The master host unit includes noise filter, inrush current limiter, primary protection
