IFAMPSU, internal power-supply module
1000W switching power supply module. Connects to the mains, supports 230Vac or 115 Vac, 50/60 Hz input voltages
and supplies the system with a maximum current of 40A.
Provides a 3A battery-charger capable of maintaining under charge 17Ah, 24Ah or 38Ah batteries.
The IFAMPSU module supplies power to the system by distributing it through the CAN DRIVE+ connection bar and
through two supervised outputs and a configurable relay output (configured at factory as alarm output, AUX output and
fault signalling relay).
Only one IFAMPSU module can be housed inside each metal cabinet, while each control panel can manage a maximum
of 4 modules (one for each cabinet).
Attention:
The installation of this module excludes the use of the IFM24160 power-supply module for the control panel.
IFAMPSU comes with:
• battery connection wire with thermal probe
• battery to battery connection wire
• screw for securing the module to the back of the cabinet
• wire with eyelet terminal for connection to earth
• 1 ferrite
• Instructions manual
