Supply to AVR is shunt or separate. It acts as a chopper (FET controlled) and has a double action (with reversal of output cur- rent). It is very fast (less than 5 ms detec- tion time) and very accurate (Ì_åäåÎå±1%).
EMI filters are built-in (suppresssion accor- ding VDE 0875 classK). According to more severe regulations (eÌ_ÌÇåÎå?????????????mission, suceptibility) the AVR may be supplied in a shielded box with a plug connector It is totally encapsulated and designed to be installed in a ventilated panel (ambient Ì_å¢åÎå_åÎ_ 65 Ì_åäåÎÌ?????????????C), (see outline draving page 9). Rated heat rejection : 35 W

Features

• Power supply : 100 to 140 V AC for shunt operation the supply is taken between lineand neutral for 115 / 200 V machine. Use a voltage transformer (secondary 100 V - 10 A) for other voltages. Input fuse : 6.3 A / fast.

• Output : Max. 10 A / 10 s. An internal ad- justable current limitation enables to adjust the maximum excitation current between 4 and 8 A.

• Terminal strips : 1 set of 10 terminals (J1) and 1 set of 5 (J2) for 1/4" spade clips. - Adjustment means : 9 potentiometers with 1/10" length slot to be set with a screw driver.

• C.T. input : For line voltage dip compen- sation or parallel operation. C.T. datas : se- condary current 1 A, 2 VA, class 1, (400 Hz). - 2 terminals for connection of remote volt : Adjustment pot 470 Ì__åÎå© - 3 Watts
