Technical Specifications

– Maximum power supply: 150V – 50/60 Hz
– Rated overload current: 10 A – 10 s
– Electronic protection:
– in the case of a short-circuit, the excitation current is reduced to a value less than 1A after 10 s
– in the event of loss of voltage reference, the excitation current is reduced to a value less than 1A after 1s for AREP/SHUNT, 10 s for PMG
– in the event of overexcitation, the current is reduced as indicated in the next diagram (see 3.2.1.4)
– Fast acting fuses: F1 on X1 and F2 on Z2 10A, 250V
– Voltage sensing:
? 0-110 V terminals = 95 to 140 V
? 0-220 V terminals = 170 to 260 V
? 0-380 V terminals = 340 to 528 V
For other voltages, a transformer should be used.
– Voltage regulation:? 0.5%
– Current sensing: (parallel operation): input S1, S2 intended for 1 C.T. > 2.5 VA cl1, secondary 1 A or 5 A
