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.

- 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
