Power supply module (PWS)
5.5.1
PWS structure
The power supply module (PWS) consists of a DC/DC converter and line noise filters.
There are two types for the PWS module about the DC rated voltage. The first type is for “110-
250 Vdc” rated, and the second is for “24-60Vdc” rated. One of DC rated voltage types is chosen
with the ordering table, and then the type is applicable in the PWS.

Description
110-250 Vdc 88-300 Vdc
Input voltage (110/125Vdc, 220/250Vdc) is
available where the voltage varies in ±20% of the
rated voltage (110V× 80% to 250V×120%).
24-60 Vdc 19.2-72 Vdc
Input voltage (24/48/60Vdc) is available where the
voltage varies in ±20% of the rated voltage (24V×
80% to 60V×120%).
Note: The IED composed of a PWS module whose DC rated voltage is “110-250 Vdc”, can
run on AC power supply (100–220Vac).
However, it is recommended to input AC power only for temporary operations such
as tests where DC power cannot be inputted. In addition, if the supervision function
is enabled, the IED detects the Power failure (error) when AC power is inputted.
Figure 5.5-1 shows the difference between ‘Compression plug type terminal’ and ‘Ring type
terminal’. Alpha-numeric reference “T*” identifies slot locations, and an asterisk “*” shows its
slot number. An external connection figure illustrates the PSW location (see
Appendix: Typical
External connection
