This section states the specifications of both Output Control and Metering capabilities of the UPC.
Environmental Ambient operating conditions are as follows.
Temperature 0-50ºC.
Humidity
0-95% R.H Non-Condensing.
2.1 CONTROL SPECIFICATIONS
2.1.1 FREQUENCY CONTROL SPECIFICATIONS
The UPC output frequency is variable from 15 to 1200 Hz. Internally, there are 3 FREQUENCY SPAN
ranges, each with a different resolution as determined by the number of digitized steps in the output
waveform and in the metering data. To change FREQUENCY SPAN, see 4.5.3.2.
FREQUENCY SPAN WAVEFORM STEPS METERING SAMPLES
15.00 – 150 Hz. 1024 512
15.00 – 300 Hz. 512 256
15.00 – 600 Hz. 256 128
15.00 – 1200 Hz. 128 64
Accuracy is
±
0.01% of full scale over the full range of ambient conditions.
A unique feature available within the UPC is TRANSITION TIME. If Transition time is set to a non-zero
value, and a new program is executed, or changes are made in MANUAL MODE (or by REMOTE
CONTROL), the UPC will take the specified time to transition from the active voltage and frequency to
the new voltages and frequency. This feature may be used when it is undesirable to cause abrupt
changes to the output power signal. This feature does not affect transient operation. Transition time may
be set from 0 to 300 seconds in increments as small as 200 uSec.
