Ta=20°C.
3. Optical indication.
The PSU is fitted with 4 green
L1÷L4 LEDs at the PCB, indicating DC voltage at the AUX1÷AUX4 outputs.
During normal operation, the LED is permanently illuminated. In case of short-circuit or output overload, the LED is
off.
4. Service and operation.
4.1 Overload or short-circuit of the power supply output (SCP activation).
The
AUX1÷AUX4 outputs of the PSU are individually protected against short-circuit by
melting fuses. In
case of fuse replacement, use only compatible replacement parts. If the output load current exceeds
Σ4,0A@30 V
DC (110% ÷ 150% of the S power), the F fuse in the 230 V AC circuit and/or F1÷F4 fuses become permanently
damaged. In case of failure, replace the fuse with the same type.
4.2 Maintenance.
All maintenance procedures can be performed after disconnecting the power supply from the power
network. The PSU does not require any specific maintenance; however, its interior should be cleaned with
compressed air if used in dusty conditions. In case of fuse replacement, use only compatible replacement parts
