Voltage Regulator Replaces Basler VR63-4 and Marathon SE100A

Universal *Basler-style Regulator has improvements like a heat sink, on-board fuse, stability adjustment, and multi-voltage input. This is also an exact replacement for Marathon SE100A (Marathon part # B-526097)  Replaces Marathon #761560-01 and Basler VR63-4.  Will Basler VR63-4C on the 120 volt position, but if you need more than 36VDC output, we recommend our VR230.

Will also replace Leroy Somer R210 with the voltage selector set at 120 volts on this AVR.

Rated @ 63 volts and up to 5 amps DC output on exciter fields as low as 12 ohms. Voltage regulator has been successfully used for Onan JB & JC series gensets. (Can be used to replace Onan # 305-0688 or 300-1540 with simple wiring change.) Contact us for details.

Rated for either 120V (90-132 volts) sensing & power input OR 171-264 volts sensing & power for 208 / 220 or 240 volt generators.
There is a small selector switch on the voltage regulator to choose the input voltage you have connected to. (The machine MUST be wired correctly for the appropriate input voltage FIRST!) Can run on 110-120V, or 208, 220 or 240 volts by flipping a small switch on the regulator! Sensing and power input are supplied on the same input wires # 3 & 4.

Note that 120 volt input reduces DC output to approximately 36 volts output.

WARNING: Moving the voltage switch while the generator is running may damage the regulator and will void the warranty!
