The control panels are equipped with a Fly-back type switching power supply model ALSW285PFC providing a maximum output
current of 5A @ 24V DC (default calibration 28.8V DC @ 25°C). The power supply is equipped with an integrated PFC circuit
(Power Factor Correction) which interrupts current supply when there is no power demand. Therefore the power supply only starts
working with a load superior to 50mA. The connection to the control panel is made via a polarized connector. The wiring transfers
to the control panel the power supply as well as diagnostic.
N.B. The voltage value measured at the battery charger output is subject to variations, due to the temperature of the battery.
The battery temperature is measured by a probe mounted on the battery surface.
Input protection
The 230V AC mains input is protected against overvoltage by varistors and by a non replaceable fuse integrated in the electronics
(F1:T1.6A - T). Fuse blowing is necessarily attributed to a failure, or an exceptionally violent electromagnetic discharge that would
inevitably require repair.
Output protection
The output section of the power supply is automatically protected against short circuits and overloads. If one of these conditions
occurs, the device deactivates and then reactivates automatically when the cause of the cut-off is removed or normal operating
conditions are restored.
