| Input |
| Voltage |
24VDC, 28VDC, 36VDC, 48VDC, 120VDC, 200VDC, 250VDC,
384VDC are listed in tables. 60VDC and others are available on a
custom basis |
| Voltage Range |
±20% typical |
| Output |
| Voltage |
Single Phase-115V for 60Hz and 400Hz outputs, 220V
for 50Hz output. Other voltages available. Consult factory |
| 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, consult factory.) |
| 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 |
| Waveshape |
Sinewave less than 2% 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 zero lead to zero
lag at full rated output without damage |
| Peak Output Current |
110%, subcyclic reset |
| Duty Cycle |
Continuous at full rated output |
| Efficiency |
Between 60 to 90 percent depending upon DC input
voltage. Typically 70% from 40% of full load to full load |
| Configuration |
Input to output is transformer isolated and floating.
Either side may be grounded. Three phase output is four-wire neutral
floating or grounded. (Delta output available as no charge option.) |
| Phase Angle Accuracy |
Digitally controlled to within ±2 degrees
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 and
elapsed time meter are offered as options |
| Environmental |
| Ambient Temperature Range |
Operating 0° to 40°C. Non operating -20°
to +85°C. Extended temperature range available as an option |
| Ambient Humidity Range |
Less than or equal to 95% to 25&dge;C, less
than or equal to 75% to 40°C and less than or equal to 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" rack
mount. Larger units are cabinet models |
