Abstract: An electronics (100) configured to determine an input voltage to a galvanic isolation point of the electronics (100) is provided. The electronics (100) comprises an isolation transformer (120) configured to conduct a primary current (Ip) provided by an input voltage source (110), and provide a secondary voltage (Vs), the secondary voltage (Vs) being proportional to a primary voltage (Vp) induced by the primary current (Ip). The electronics (100) also comprises a peak detection circuit (130) coupled to the isolation transformer (120), the peak detection circuit (130) being configured to receive the secondary voltage (Vs) and, based on the secondary voltage (Vs), provide a signal that is proportional to the primary voltage (Vp).
