Cosel announced the release of two new models of high power density, 300W and 1000W power supplies with extended communications I/O for demanding medical and industrial applications. The addition of the 300W PCA300F and 1000W PCA1000F to the existing 600W PCA600F complements and expands the family of power supplies to cover a much larger range of applications.
The PCA series have a built-in extended-UART (Universal Asynchronous Receiver –Transmitter) interface supporting up to 83 commands to monitor and control the whole range of power supply parameters. A PMBus version will be available in Q4-2019. Complying with stringent medical standards EN/IEC 60601-1, the PCA300F and PCA1000F feature a reinforced input to output isolation of 4,000VAC and a grade of 2X Means of Patient Protection (2xMOPP). The PCA series offer a universal input voltage of 85 to 264VAC, as well as a DC input of 88 to 370VDC. Exhibiting flexibility, the output can be operated in constant voltage (CV) or constant current (CC) mode with either analog or digital control. All PCA series power supplies are built-in 1U height housings and utilize Cosel’s high-density, integrated packaging with optimized cooling.
Available in six different output voltages, the PCA series covers the whole range of applications from 5V to 48V and embraces 5, 12, 15, 24, 32 and 48V. All output voltages can be adjusted to near zero volts and operated in constant voltage or constant current mode. In addition to the main output, an independent isolated auxiliary voltage of 12V is provided which is adjustable in the range of 4.7 -12.6V DC using digital control.
Designed for demanding applications, and in line with their predecessor, the PCA600F, the PCA300F and PCA1000F combine the benefits of constant voltage and constant current, simplifying designers’ task when developing power systems requiring both modes without adding external circuitry e.g. lead-acid battery charging requiring constant current charging up to 90%, and constant voltage above that.
