R448 A.V.R.3.1 – Characteristics- Shunt power supply: max 150V – 50/60 Hz- Rated overload current: 10A – 10s- Electronic protection: (in the event ofoverload, short-circuit, loss of voltage sensing)this acts to restore the value of the excitationcurrent to 1A after 10 s. The alternator must bestopped (or the power switched off) in order toreset the protection.- Fuse: F1 on X1, X2. 10A ; slow – 250V- Voltage sensing : 5 VA isolated via trans-former• 0-110 V terminals = 95 to 140 V• 0-220 V terminals = 170 to 260 V• 0-380 V terminals = 340 to 520 Vfor other voltages, a transformer should beused.- Voltage regulation ± 0.5%- Normal or rapid response time via jumperST2 (see below)- Voltage adjustment via potentiometer P2 orapply a DC voltage of ± 1 V on the terminals ofthe external potentiometer- Current sensing: (parallel operation): inputS1, S2 intended for 1 C.T. Š 2.5 VA cl1,secondary 1A (optional)- Quadrature droop adjustment via potentio-meter P1- Max. excitation current adjustment via P5:4.5 to 10A (see below)- 50/60 Hz selection via ST3 jumper- ST11: Knee-point at 65 Hz for Tractelecapplication and variable speed
