PS9401-2420-0000 – Redundancy Module
The PS9401-2420-0000 is a redundancy module that can be
used to construct 1+1 and N+1 redundant systems.
It has two input channels, to which power supplies with an
output current of up to 12 A can be connected, and an output
that can carry nominal currents up to 20 A. The output can also
be operated with up to 24 A if the ambient temperature is <
+45 °C.
The redundancy module uses MOSFET technology instead of
diodes for decoupling the two input channels. This reduces the
heat development and the voltage drop between input and
output. Due to the low power loss, the device is very narrow and
requires a width of just 32 mm on the DIN rail.
Large connection terminals enable secure and fast installation.
The redundancy module requires no additional auxiliary voltage.
Due to the international approvals package, the device is
suitable for virtually every application.
Observe the connection instructions in the chapter " Parallel use
for 1+1 redundancy [ } 29] "!
PS9011-2420-0001 – Buffer Module
The PS9011-2420-0001 buffer module is an additional device
for 24 V DC power supply units. It supplies power to bridge
typical mains power failures or extends the hold-up time after
switching off the AC voltage.
If the power supply unit supplies sufficient voltage, the buffer
module stores energy in the integrated electrolytic capacitors. In
the event of a failure of the mains voltage, the stored energy is
supplied to the DC bus in a controlled process.
The buffer module can be connected at any point in parallel with
the load circuit and does not require any control wiring.
A buffer module can provide 20 A of additional power and can
be added in parallel to increase the output current or hold-up
time.
the PS9011-2440-0000 buffer module can optionally be used to
achieve longer hold-up times.
