Power supply module (PWS)

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.

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

available where the voltage varies in ±20% of the

rated voltage (110V× 80% to 250V×120%).

Input voltage (24/48/60Vdc) is available where the

voltage varies in ±20% of the rated voltage (24V×

80% to 60V×120%).
