4.2.1.5 External Variac Control, external synchsonisation (44)
Via this special interface, the external variac can be controlled by the TRA3000 F-S-D-V-C. The external
variac is needed for EUT (>12 A) and mains voltage variation (>5A).
External synchronsation
4.2.1.6 Attention, refer to manual (45)
This expression requests the operator to consult the manual in detail. Only trained personnel are allowed to
operate the TRA3000 F-S-D-V-C.
4.2.1.7 EUT Power 1; Inputs (46,53)
All input plugs and fuses for EUT power 1 are located in row (46). The two 16 A fuses for phase and neutral
located above. Below the fuses are the three power line connections for the EUT power supply (53). For
the phase, two plugs are available for connecting the internal variac to the power. For external variac
operation, the bridge (53) and (54) must be removed, see Chapter 6 „Testing with the TRA3000 F-S-D-V-
C“.
Supply data: min. 20 to max. 250 V a.c 16A
Supply data: min. 20 to max. 110 V d.c 10A. Only applicable for TRA versions witouth TRA3000 ..D-V
included. When the TRA2000 ….D-V is included see 4.2.1.9 and 4.1.2.17
4.2.1.8 Internal Variac (55)
For the interruption and variation mode tests different voltages are needed. As standard the TRA3000 F-S-
D-V-C has an internal variac with a continuous current rating of 6 A. At shipment, two bridges are inserted
(53) and (54). The variac is protected with its own fuses. For external variac operation, the two bridges
must be removed, see Chapter 6 „Testing with the TRA3000 F-S-D-V-C“.
