Motor Induction, 1500 RPM, 4-pole Continuous duty, Class F insulation, open drip-proof Selection of 50 Hz, 3-phase input voltages to include: 208V, 220V, 380V or 416V Generator Brushless synchronous, 1800 RPM, 4-pole Continuous duty, Class F insulation, open drip-proof Selection of 60 Hz output voltages to include: 120/240V, 1-phase, 120/208V, 3-phase or 277/480V, 3-phase Rated at 0.8 power factor to insure proper handling of inductive loads Mechanical Construction Motor and generator mounted on rigid steel base V-belt drive system Complete OSHA belt guard Forklift or pallet jack provisions Standard Control Systems Each motor-generator set is equipped with a control panel that can be wall-mounted, floor-standing or unit-mounted. The standard package includes the following components: Motor Controls Motor starter with adjustable overloads Start-Stop push-buttons with terminal strip for remote start/stop Control power transformer with fusing Pilot light to indicate ?Motor Run? Generator Controls Analog meter package to include voltmeter, ammeter and frequency meter Voltmeter and ammeter phase selector switches (3-phase systems) Voltage regulator, ±1% regulation accuracy, with automatic buildup and rheostat for control of regulated voltage Output circuit breaker, molded case, to protect generator against short circuit or prolonged overload Pilot light to indicate ?60 Hz Load On? Performance Characteristics Voltage regulation: ±1% from no-load to full-load at rated power factor Voltage steady state stability: ±0.5% from no-load to full-load at rated power factor Voltage adjustment range: ±10% in stepless increments of nominal output voltage Frequency regulation: 60 Hz ±1.5% output from no-load to full-load Voltage transient: When a full-load at rated power factor is applied or released, the resultant instantaneous droop or overshoot will not exceed 30% of preset value Voltage recovery time: After a full-load is applied or released, the output voltage will return to the regulation band within 500 milliseconds Harmonic distortion: Less than 3% max. total distortion factor and less than 2.5% max. single-phase when measured line-to-line Ambient operating conditions: Temperature at 40°C, relative humidity at 95% (higher temperature rating for outdoor use available upon request) Duty cycle: Motor-generator set and controls are rated for continuous duty Motor-Generator Options Sound-reduced enclosure Weather-resistant, NEMA 3R enclosure Casters for portability Oversized generator to support motorstarting transients Thermal bearing and winding protection Unit mounted control system Input disconnect or circuit breaker Input phase protection relay Electronic soft start for drive motor Generator reconnection switch to allow selection of multiple output voltages Generator over/under voltage protection Digital meter package Remote meter package with start/stop controls protector.
