Cosel released a 200W, open-frame, configurable AC/DC power supply with triple outputs tailored for robotic controllers and factory automation. The Cosel RB series offers three configurable isolated outputs, one with a reinforced isolation to power IGBT or equivalent applications. Certified to EN62477-1 OVC III, it reduces the need for an extra isolation transformer when connected to a distribution panel.
Fully digitally-controlled on the input and output stages, the convection-cooled RBC200F accepts input voltages from 84Vac to 264Vac for an output of 207W and can be operated from -20°C to +70°C and can be installed in any orientation. The RBC200F’s master output (Slot 1) can deliver 24V (adjustable 22.8 to 26.4V), or 48V (adjustable 45.6 to 52.8V) at 144W. The second output (Slot 2) can host configured modules of 3.3V/5A; 5V/5A; 12V/2.5A; 16.5V/1.9A; 24V/1.3A; 48V/0.65A; +/- 12V/0.7A and +/-15V/0.7A with a power of 16.5 to 30W depending on the output voltage. The third output (Slot 3) can host any of the single output voltage modules in the same power level. For higher voltages, outputs can be connected in series. All output voltages are adjustable via a built-in potentiometer.
The master output DC/DC converter is based on an LLC resonant topology when the second and third outputs are using Quasi-Resonant-Flyback topology. The RBC200F as an input to output isolation of 3,000VAC, and an input to ground isolation of 2,000VAC. The isolation voltage between the three outputs has been optimized for robotic controllers applications. Isolation between the master output and output two corresponds to a functional isolation of 500VAC when the isolation between the master output, output two and the third output is reinforced to 3,000VAC.
