Peak current measurement: Valid for phases A, B,
and C (use phase A for Parallel Mode)
• Range 1: 0A to 28A; 3ø mode, 312V range
• Range 2: 0A to 56A; 3ø mode, 156V range
• Range 3: 0A to 84A; parallel mode, 312V
range
• Range 4: 0A to 168A; parallel mode, 156V
range
• Accuracy: ±5% of range, 40 to 500 Hz; add
±1%/kHz, 500 Hz to 5 kHz
Power Measurement: Valid for phases A, B, and C.
Up to 3ø total power and parallel mode (use phase A
for Parallel Mode)
• Range 1: 0 kW to 1.8 kW; 3ø mode
• Range 2: 0 kW to 5.6 kW; parallel mode and
total 3ø power
• Accuracy: ±2.5% of range, DC or 40 to 500
Hz for crest factors <2.0. Add ±1% for crest
factors up to 4.0. Add ±1%/kHz above 500 Hz
VA Measurement: Valid for phases A, B, and C. Up
to 3ø total VA and parallel mode (use phase A for
Parallel Mode)
• Range 1: 0 kW to 1.8 kVA; 3ø mode
• Range 2: 0 kW to 5.6 kVA; parallel mode and
total 3ø power
• Accuracy: ±2.5% of range, DC or 40 to 500
Hz for crest factors <2.0. Add ±1% for crest
factors up to 4.0. Add ±1%/kHz above 500 Hz
Power Factor: Valid for phases A, B, and C (use
phase A for Parallel Mode)
The Power Factor is calculated from the Power and
VA measurements
• Range: 0 to 1.00
• Accuracy: ±5% of range at full power, DC or
40 to 500 Hz for crest factors <2.0. Add ±2%
for crest factors up to 4.0. Add ±1%/kHz above
500 Hz
Frequency Measurement: Frequencies are
calculated based on output zero crossing time
measurements
• Resolution: Frequency is displayed to 5 digits
max; leading zeros are blanked. Displayed
resolution is
0.01 Hz
• Accuracy: ±0.5% of reading, at 10% to full
output voltage, 0°C to 45°C
Phase Measurement: Valid for phases A, B, and C
relative to each other
• Resolution: ±1°
• Accuracy: ±2°, 40 to 500 Hz; add ±2°/kHz
above 500 Hz. For sine wave, balanced resistive
load, 10% to 100% of voltage measurement
range, 0°C to 45°C
INPUT
Input Voltage Ranges: Factory confi gured 187 to
264 VRMS, 3ø L-L (3 wire), or 342 to 457 VRMS,
3ø L-L (4 wire). A chassis ground is also required.
115 or 230 VAC single-phase is required for PDU in
10.5-21 kVA systems. (400 Hz input allowed with
PFC option)
Input Power Factor: 0.6
(.35 for Intl. Rectifi er; 0.99 with PFC option)
Note: With PFC option the inputs may be paralleled and wired for
single phase input. Consult factory.
Input Frequency Range: 47 to 63 Hz
Effi ciency: 70% min., at full load
Ride Through: 3 ms min.; 10 ms min., with PFC
option
PROTECTION AND SAFETY
Overvoltage Shutdown: Programmable for 15V to
255V peak, 156V range; 30V to 510V peak, 312V
range
Programmable Current Limit Shutdown: Settable
to 1% of range (0.5A to 13A for 156V range; 0.5A to
6.5A for 312V range)
Programmable Current Limit with Timed
Shutdown: Settable to 1% of range: the timeout is
settable from 100 ms to 10s.
Programmable Constant Current: Settable to 1%
of range (0.5A to 13A for 156V range; 0.5A to 6.5A
for 312V range). For all current accuracies ±1%
of fullscale, add ±1.5%/kHz above 500 Hz. For
paralleled amplifi ers, add ±1%.
Overtemperature Shutdown: (automatic, not
programmable)
