The Block Signalling PSU4 is the big brother of the PSU1, this module is great if you require more 12v DC accessory points to operate on your layout.
This module can also be linked to a second PSU4 if required to provide even more power supply flexibility.
The BLOCK Signalling PSU4 module provides 12 stable 12V DC power supplies where only a single AC or DC power supply is available.
The input automatically adjusts for all power inputs in the range of 5V to 25V DC or 9V to 24V AC and produces a number of stable 12V DC outputs.
The input can be wired to the input terminals, or if you are using a plug-top power supply this can be plugged into the 2.1mm jack. The module is not sensitive to the polarity of the input.
The 12V DC outputs are protected by a 1A self-resetting fuse, so in the event of a short circuit or overload the power will be cut and then automatically reconnected after the fault has been cleared and the fuse has had time to cool.
