2 SPECIFICATIONS
This section states the specifications of both Output Control and Metering capabilities of the UPC.
UPC-12 is assembly number: 133700
UPC-32 is assembly number: 133600
Environmental Ambient operating conditions are: Temperature: 0-50°C.
Humidity: 0-95% R.H Non-Condensing.
2.1 CONTROL SPECIFICATIONS
A unique control feature available within the UPC is TRANSITION TIME ( 4.6.3.1 , 5.4.1 ). When Transition
Time is set to a non-zero value (0 to 300 Sec. in increments as small as 200 uS), any change of the
voltage or frequency, whether by executing a new Program or by Manual or Remote command, will take
the specified time to transition to the new voltage and frequency. This is useful when abrupt changes to
the output power signal are undesireable. This feature does not affect transient operation.
2.1.1 FREQUENCY CONTROL SPECIFICATIONS
The UPC output frequency is variable from 20 to 5000 Hz. Internally, there are 3 frequency ranges, each
with a different resolution. The user need NOT be concerned with changing these ranges as the UPC
auto-ranges based on the selected frequency.
RANGE RESOLUTION
20.00 - 99.99 Hz 0.01 Hz
100.0 - 999.9 Hz 0.1 Hz
1000
– 5000 Hz
1.0 Hz
Accuracy is ± 0.01% of full scale over the full range of ambient conditions.
2.1.2 VOLTAGE CONTROL SPECIFICATIONS
The voltage amplitude of each vector can be varied independently.
There are two output coupling modes selectable in the stored programs of the UPC.
1) DIRECT COUPLED MODE:
Range: 0 to 150 VAC rms
Resolution: 0.1 volts
Output Ratio: 1.0 (This mode is internally fixed)
2) TRANSFORMER COUPLED MODE:
Range: 0 to (150 x XFMR RATIO) VAC rms (maximum of 600 volts)
Resolution: Dependent upon the TRANSFORMER RATIO as described below.
This allows for a possible output voltage of up to 375 VAC rms line-
neutral, using an output TRANSFORMER RATIO of 2.5.
The voltage range available at any time is calculated by the UPC and accounts for the set Transformer
Ratio (
3.7.1 , 4.6.3.3 ). The power source will produce the correct amplitude signal and does NOT require
the user to perform any calculations to determine output voltage dependant upon the transformer ratio.
