1 - GENERAL DESCRIPTION
The R130 is an AVR designed for ARÈS,
ARCM or ACTR type compound excitation
alternators.
The R130 is a transistor-controlled AVR.
The measured voltage is ltered and rectied.
It is not a󰀨ected by voltage variations caused
by non-linear loads.
It is totally sealed with an elastomer which
protects it from environmental stresses.
The replacement kit includes:
- 1 AVR R130
- 1 Resistance R01
Note: According to available space, this kit can
be mounted inside the generator terminal box
or in control panel.
R130 AVR functions:
- AVR accuracy +/- 1.5%
- Underspeed protection
- Parallel operation between alternators thanks
to reactive droop compensation
- External potentiometer connection wires, for
voltage adjustment (470 ohms: voltage range
+/- 5% - 3 W, or 1000 ohms: voltage range
+/- 10% - 3 W)
- Wires for parallel operation CT output 1 A - 5 VA
- 220 V or 400 V power supply
- 10 VA voltage sensing isolated via trans-
