Overview
PS9011-2440-0000 | Buffer module 24 V, 40 A, 160 ms
• Buffering with electrolytic capacitors
• Buffering of 24 V loads
• Minimum hold-up time 0.16 s at 40 A, longer hold-up time with smaller loads
• Clear status display by Status LED and signaling terminals
• Extra-large screw terminals
The PS9011-2440-0000 Buffer Module is an additional device for regulated 24 V DC power supply units that
can be used for various purposes:
• Bridging of failures of the DC supply network with additional power
• Extension of the hold-up time after failure of the AC voltage.
• Short-term provision of an additional peak current that is higher than the nominal current of the power
supply unit.
The buffer module uses maintenance-free electrolytic capacitors to store energy. This enables use even at
ambient temperatures up to +70 °C.
The device requires no control wiring. It can be connected anywhere in parallel with the load circuit.
Buffer modules can be connected in parallel in order to increase the output current capacity or the hold-up
time
