| Input |
| Voltage |
24/28/36/48/120/200/250/384/600 VDC (listed in tables).
60 VDC and others are available on
a custom basis. |
| Voltage Range |
-15%, +20% typical |
| Output |
| Voltage |
120/208 V, 60 Hz; 220/380 V, 50 Hz.
Other voltages available. Contact MajorPower.Com |
| Voltage Regulation |
2% or less for combined no load to full load
changes and rated input voltage changes. |
| Frequency |
Rated output frequency for each model is shown
on chart.
(Custom output frequencies are available. Contact MajorPower.Com) |
| Frequency Stability |
Oscillator included in the unit base
price.
Fixed frequency oscillators are crystal controlled with a
stability of ±0.05%. |
| Power |
Rated output power for each model is shown on
chart opposite model number. Maximum power per phase is 1/3 of the three-phase output. |
| Waveshape |
Sinewave less than 3% THD, 1% max, any single
frequency.
Less than 4% for non-linear loads such as computer power
supplies. |
| Load Power Factor |
0.7 lead to 0.7 lag. Continuous 0 lead to
0 lag at full rated output without damage. |
| Peak Output Current |
110%, subcyclic reset |
| Duty Cycle |
Continuous at full rated output |
| Efficiency |
Between 70 - 90% (typically 75%) depending upon DC input
voltage. |
| Configuration |
3-phase, four-wire neutral floating. (Delta output available as no charge option.) |
| Phase Angle Accuracy |
Digitally controlled to within ±2°
for balanced loads, for fixed or adjustable outputs. |
| Protective Circuits |
All models are equipped with automatic overload
protection, including short circuit. Automatic reset upon overload
removal. Circuit breaker or fuse on the input and fuse on the output.
Automatic shutdown for input over-voltage, undervoltage. |
| Meters |
Output voltmeter, ammeter, frequency meter &
elapsed time meter offered as options. |
| Environmental |
| Ambient Temperature Range |
Operating 0° to 40°C. Non operating -20°
to +85°C. |
| Ambient Humidity Range |
±95% to 25°C, ±75% to 40°C and ±45% to
50°C |
| Mechanical |
| Input and Output Terminations |
Rear mounted barrier strips provided. High current
DC inputs have brass studs or bus bar. Rear mounted MS connectors
and mates provided 4kVA or less 400Hz output units. |
| Construction |
Units less than 6KVA are standard 19" Rackmount. Larger units are cabinet models. |
