COSEL’s configurable power supplies shorten time to market for medical applications

12 SEPTEMBER 2019

Cosel Co, Ltd announced a complete line up of configurable power supplies for medical applications, the AME series. Based on COSEL’s digital power expertize and optimized topology for high efficiency, the AME series comprises of four models, AME400F, AME600F, AME800F and the AME1200F, together covering applications from 400W to 1200W. Each version can host independent output modules that can be combined and mixed to offer a unique configuration as required by 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. Designed for demanding medical applications, the AME series input/output isolation complies with 2MOPP requirements.
The AME modular concept is extremely flexible. Each 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 to power demanding applications where space can often be limited, the AME series is housed in a low profile case.
The AME400F and AME600F measure 89 × 41 × 257mm (3.50 × 1.61 × 10.12 inches) and the AME800F and AME1200F 127 × 41 × 257mm (5.00 × 1.61 × 10.12 inches).
