MTS-1720 TWO CHANNEL CURRENT SOURCE
9.1 INTRODUCTION
The MTS-1720 provides two current output channels in to complement the MTS-1710, and to produce true
3
Φ
current output.
Control of the output amplitude, phase, frequency and all other capabilities are provided through the MTS-
1710 front panel. All the advanced control and measurement capabilities, including the prefault/fault/
postfault levels, ramping, fault phase selection, and interphase angle display of the MTS-1710 are provided
in these additional two current channels.
9.2 SPECIFICATIONS
NOTE:
All specifications are subject to change. All AC quantities are RMS values, except as otherwise
noted.
Power outputs are specified for nominal 120VAC/60Hz or 240VAC/50Hz power input, and
25
°
C ambient operating temperature. Derating applies for lower input power voltages and
higher ambient temperatures.
For all current outputs, maximum obtainable current will vary inversely with load impedance.
For extended operation at high power output levels, ensure adequate cooling (i.e. tilt stand
raised to aid air flow to bottom inlets, and adequate clearance for exhaust outlets).
9.2.1 Inputs
Single phase 105-130VAC @ 15A max (or 210-250VAC @8A max), factory set.
9.2.2 Outputs
Two current channels
Each channel:
0-30 A rms, 400VA maximum, 44 V rms maximum
Typical performance per phase:
