1606-XLC Wall Mounting Bracket
This bracket is used to mount specific units onto a flat surface without using a
DIN rail.
1606-XLSBUFFER48 Buffer Module
This buffer module is a supplementary device for DC 48V power supply units.
The module delivers power to bridge typical mains failures or extends the hold-
up time after turn-off of the AC power. In times when the power supply unit
provides sufficient voltages, the buffer module stores energy in integrated
electrolytic capacitors. If there is a mains voltage fault, this energy is released
again in a regulated process.
The buffer module does not require any control wiring. It can be added in
parallel to the load circuit at any given point. Buffer modules can be added in
parallel to increase the output ampacity or the hold-up time.
1606-XLSRED40HF Redundancy Module
The 1606-XLSRED40HF redundancy module is equipped with two input
channels of 20 A each, which are individually decoupled by using mosfet
technology. The output current is up to 40 A.
Mosfets are used instead of diodes to reduce the heat generation and voltage
drop between input and output.
