Schematic diagram of the energy supply

V IN 12...32 VDC
Power consumption

(without sensors)

typ. <1 mW 1)

max. 12 W

Reverse voltage protection No 2)

1) applies to continuous operation if the possibly available rechargeable battery of the power supply unit is fully charged

2) The reverse voltage protection is part of the protective circuit in the power supply units.

Regardless of whether an external supply or charging voltage is provided (e.g. by a power supply unit), a power supply unit must always be installed in the device. A selection of compatible power supplies is included in the chapter Charging devices and power supply units. Depending on the type, the power supply unit contains a rechargeable battery (PSU413D+ AP , a battery (PSU713 BP ), or only a protective circuit (PSU DC ). A list of compatible PSUs is included in the chapter Power supply units. An external supply or charging voltage is not required if the power supply unit is equipped with a battery.
