PSL13x low-voltage
power supply unit
PSL 130
PSL 130 power supply unit for HSCI components with
+24 V power supply when using a HEIDENHAIN inverter
system
The PSL 130 power supply unit was conceived in order to
be able to provide the HSCI components of the iTNC 530
HSCI with +24 V NC voltage and +24 V PLC voltage.
The output voltages of the PSL 130 fulfill the requirements
for Protective Extra Low Voltage (PELV) according to
EN 50178. The power supply unit is powered with line
voltage (L1, L2) and the DC-link voltage Uz.
This is used to produce the +24 V NC and +24 V PLC
output voltages.
PSL 135
PSL135 power supply unit for supplying the HSCI
components in a multi-row configuration or for using a non-
HEIDENHAIN inverter system
The PSL 135 power supply unit was conceived in order to
be able to provide the HSCI components of the iTNC 530
HSCI with +24-V NC voltage, + 24-V PLC voltage and +5 V.
The output voltages of the PSL 135 fulfill the requirements
for Protective Extra Low Voltage (PELV) according to
EN 50178. The power supply unit is powered with line
voltage (L1, L2) and the DC-link voltage Uz.
This is used to produce the +24 V NC, +24 V PLC, and +5 V
output voltages.
