CHARACTERISTIC
- Storage : -55°C ; +85°C
- Operation : -40°C ; +70°C
- Standard power supply: AREP or PMG.
- Rated overload current: 8 A - 10 s
- Electronic protection (overload, short-cir -cuit on opening of voltage sensing circuit): excitation overload current for 10 seconds then return to approximately 1A. The alter -nator must be stopped (or the power switched off) in order to reset the protection.
- Fuse : F1 on X1, X2. 8A ; 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 V.
- Voltage regulation ± 1%.
- Normal or rapid response time via ST2 jumper (see below).
- Voltage adjustment via potentiometer P2.other voltages via adapter transformer
- Current sensing (parallel operation): C.T 2.5 VA cl1, secondary 1 A (optional).
- Quadrature droop adjustment via potentio -meter P1.
- Max. excitation current adjustment via P5
