10 M447352-01 REV-A
Voltage slew rate,
typical
< 0.5 V/micro sec
DC Offset Voltage,
Typical
< ±20 mVDC
Output Noise
Low V Range: < 2 VRMS
High V Range: < 3 VRMS
Bandwidth 20kHz to 1MHz for AC output.
Output Coupling DC coupled for 166V/ 333 V range.
On optional -XVC Voltage range output, which is AC coupled; only AC mode is
supported.
Load Power Factor 0 to unity at full output current
Current limit Accuracy
± (0.3% of actual + 0.5% of full-scale) for DC & AC
16 Hz to 905 Hz; add ±0.1% of full-scale for AC+DC mode. Valid from 10% of full-
scale to 100% of full-scale.
Full scale for SQ0022&TA0022/SQ0030&TA0030 are considered as 125A for
accuracy calculation.
Frequency Range
Standard: 16 Hz - 550 Hz (for –XVC option range, 45 Hz – 550 Hz)
HF option: 16 Hz – 905 Hz
Ext. Sync Mode (not available with FC option)
Input: Isolated TTL input for external frequency control. Requires 5V at 5 mA for logic high.
Accuracy:
Ext. Sync to phase A with fixed Ext. Sync Frequency input:
16 Hz - 100 Hz: < 2°
> 100 Hz - 500 Hz: < 3°
> 500 Hz: < 4°
