Abstract
A medical fluid heating system operable with different supply voltages including first and second heater elements: first and second power lines, first, second and third switches in electrical communication with the first and second power lines, the switches configured such that (i) in a first switch state the first and second heater elements are placed in series, solely via a closing of the first switch, for operation with a first supply voltage applied to the first and second power lines, and (ii) in a second switch state the first and second heater elements are placed in parallel, via the second and third switches, for operation with a second supply voltage applied to the first and second power lines, and a control element configured to automatically set the switches in the first or the second switch state based upon a signal sent to the control element indicative of the first or the second supply voltage.
