DESCRIPTION
.
The fuse module is designed for power distribution in the power supply units of EN54C series. It
contains two power inputs, IN1 and IN2, connecting to the power supply and eight independently secured
outputs AUX1÷AUX8. The IN1 input supplies power to the AUX1 and AUX4 outputs, while the IN2 input
supplies power to the AUX5 and AUX8 outputs. Each AUX output has short-circuit protection (SCP) in form of
F 0,5 A melting fuse (it is possible to install F1 A fuses - not included). Outputs condition is indicated by L1÷L8
LEDs. Fuse activation is indicated by: turning off the corresponding LED: L1 for AUX1, L2 for AUX2 etc.,
technical output relay type and PSU LED. PSU technical output can be used for remote control of the
parameters, e.g. external optical indication
