High power density power module offers a compact low profile

12-08-2020 | Cosel | Power

COSEL has added a 1.2kW, compact and low profile, onboard AC/DC power module. Created for demanding worldwide applications, the TUNS1200 offers an input voltage range of 85VAC to 305VAC and is certified to satisfy industrial and medical standards. Packaged in a sealed plastic case with aluminium baseplate the device has a height of only 12.7mm (0.5") and weighs less than 280g. Compared to existing 1kW onboard AC/DC modules, the device’s footprint is 36% smaller while delivering 21% more power.


The unit can be operated from -40C to +100C baseplate temperatures. The modules can be paralleled up to nine units (up to 9,750W), their output voltage can be adjusted down to zero volts and is simply set to constant voltage or constant current operating modes.


Thanks to the company's high-efficiency topology, the device delivers 21% more power in a 36% smaller footprint than existing AC/DC modules.


Packaged in a sealed housing with an aluminium baseplate, the device is the latest member of the TUNS series, which includes a 50W ¼ brick, 100W ½ brick and 300, 500 and 700W full brick units. Designed with the latest technology, the device offers its full power up to +85C baseplate temperature and can operate safely at up to +100C with a derating.






Benefiting from a design optimised for conduction cooling, the device is ideal for applications needing a silent power solution such as in a surgery room. Equally, it is ideal for industrial applications when forced air ventilation is impossible due to environmental constraints. Attached to a chassis or cold plate, the device can produce impressive power with a high level of reliability.


The power supply complies with the RoHS directive and is CE marked in accordance with the Low Voltage Directive.
