Functional description
NA22 and NA24 are emergency rescue devices used to move the elevator to the nearest floor to be used in a traction and hydraulic lift
During normal operation, it recharges the battery. In case of power failure, it will take the energy from the battery and using its inverter, generates a three-phase voltage to restore power to the control panel and the door operator, allowing passengers to exit
Application fields
- For hydraulic elevators to open descending valves, give power to the control cabinet and to the door operator
- For traction lift to open the brakes, give power to the control cabinet and to the door operator
Main features
- Battery Type: 12V (NA22) or 24V (NA24) 7.2Ah Solid State
- Emergency cycle duration: 120 seconds
- Output three-phase inverter: 8-12V(NA22), 16-18 VA(NA24)
- Maximum output power: 200W (NA22), 400W(NA24)
