1. Technical description.

1.1. General description.
The LB5 (AWZ534) fuse block is used for power distribution in a low-voltage systems (power distribution). It
has the IN input for power connection, i.e. 10V-30V/DC or 10V-24V/AC (e.g. buffer power-supply, transformer, etc.).
The LB5 module features five independently protected AUX1...AUX5 power outputs. An AUX output has short-circuit
protection (SCP) as a fuse (F 0,5A or F 1,0A) and surge protection - varistors. Any output state is indicated by five L1...L5
LED's. A fuse failure is indicated by a proper LED switching-off, i.e. L1 for AUX1 etc. Moreover, if a failure occurs, the AW
output (L state) and the LED AW are activated. The AW output can be used for remote control of the LB5 state, e.g.
translocated optical signalling.
