208/380/480VAC 50/60HZ

The SS42-7 Voltage regulator is designed for use on 50/60 Hz brushless generators that have internal auxiliary power winding. This regulator includes frequency compensation, over excitation shutdown, a solid-state build-up circuit, and EMI filtering.

Specifications

• DC Output Power: 7Adc at 42 Vdc maximum continuous.
• Exciter Field DC Resistance: 6 Ohms minimum, 105 Ohms maximum.
• AC Power Input: Operating range 220 VAC to 260 VAC, 1-Phase, 50/60 Hz
• Sensing Input: 220-252 VAC +/- 10%, 2-Phase, 50/60 Hz < 1 VA Burden
• Voltage Adjust Range: 180-277 VAC.
• Regulation Accuracy: < 1% No-load to Full-load, Average Sensing.
• Paralleling: Input for 5 VAC from External C.T./Burden to allow 10% Droop.
• Response Time: Less than 1.5 cycles for +/-5% change in sensing voltage. Link (T C) and Adjustable Stability to optimize reponse.
• EMI Suppression: Internal EMI filter.
• Frequency compensation: Twice Volts per Hertz
• Over-excitation Shutdown: Inverse Time delayed, fixed setting. Trip range from no trip @ 50 VDC to instantaneous at 100 VDC. Disable link terminals (N D) provided for parallel operation.
• Voltage build-up: Internal provision for automatic build-up from 6 VAC, "Soft Start"
• Power Dissipation: 20 Watts typically.
