Power supply.
The power supply is covered by a highly resistant plastic housing. Its main function is to
convert the signals it receives from the patient's command and from the supervisor.
Everything is controlled analogically. Each actuator is controlled separately by the
corresponding handset, which can be blocked by the nurse panel. The power supply is
designed to connect to networks of 100V / 120 / 220-240V and alternating current of
50-60 Hz, so it allows its use in different countries without any problem (specify when
ordering).
The design of the power supply includes the following security systems:
• EOP safety system (electrical protection against overloads): protects the actuator
against overloads by disconnecting the current in case of overload during operation.
• EAS safety system (electrical protection against short circuits or power cut): the
power supply is designed so that the terminals short circuit the actuator when the
actuator is not in operation. This property gives the actuator a greater self-locking
capacity. It also has a safety system that cuts off the current and stops the actuators
when the consumption reaches the limit value.
• Class 1 protective earth cable to avoid the derivation of both the patient and the
users who are in contact with the bed.
It allows to connect different optional accessories, such as a 24V (1.2 Ah) external
battery for the operation of the bed without connection to the network
