T400 Controller Facilities Manual

667/EB/20200/000 Page 25-11 Issue 9

Current Transformers

Each controller phase or illuminated indicator that is to be monitored requires 1

current sensor as detailed below. The table also indicates which lamp feeds are passed

through the current sense transformer for each type.

Note 1:

These limits apply to 240W rms supply voltage and 50W lamp loads (unless

stated). Where the supply is lower or the lamp loads are higher the limits are

reduced accordingly. For example the figures given in curly brackets {}, are the

maximum loads when a 50-0-50 Vrms mains supply is used. The limits are only

reduced if the actual voltage being monitored is at the lower level, i.e. if a 50-0-

50 Vrms supply (derived from a transformer) is used but the monitoring is on

the 240V rms side of the transformer, then the limits do not need to be

reduced.
