Overview
( DataSheet : www.
DataSheet4U.
com ) VR485 SERIES VR485 SERIES VOLTAGE REGULATOR The VR485 series of voltage regulators controls the output voltage of 400Hz brushless generators.
This is accomplished by the regulator supplying the necessary excitation to the generator field.
Two styles are available.
The VR485-100-L enables line drop compensation for voltage drops induced by large line impedance to isolated loads.
The VR485100-P allows paralleling of its generator to another power source.
Both features require a 1 Amp CT input.
Power transformer BE 25089-001 is included with these regulators.
The transformer will convert 208Vac to the necessary voltages required by the regulator for proper operation.
FEATURES • Regulation accuracy better than ±1.
0%.
• Frequency compensated.
• Continuous 5 Adc field current limiting.
• Automatic generator line voltage buildup.
• Paralleling or line drop compensation as standard.
• Fast response time (less than 1.
5 cycles).
• Applicable on 400 Hz systems.
