ASX Series Power Sources can be equipped with output transformers to provide an alternate output voltage range. Selection of direct or transformer coupled range is performed by the controller via front panel or bus command. The standard frequency range for transformer coupled outputs is 45 to 1,200 Hz. Standard output ratios are 1.5:1, 2.0:1, and 2.5:1. Transformer outputs are supplied internally or externally via a Magnetics Module as listed in the above table. Consult the factory for additional information regarding special output ranges not listed above.

The latest additions to Pacific’s SmartsourceT family of UPC Controllers are the UPC-1M, UPC-3M, UPC-1 and UPC-3. The UPC Controller is a modular component of the ASX Series and is available in four configurations ranging from 1 Phase to 3 Phase and Manual Control to Programmable Control. The table below lists each model according to key features.

All UPC Controllers include precise metering functions with data displayed via a 160 character LCD display. This, along with the 30-key front panel, provides the industry’s most powerful and user-friendly controller.

The UPC-1 and UPC-3 controllers are available with either the RS-232 or GPIB remote interface. Commands are structured in accordance with SCPI (Standard Commands for Programmable Instruments). The RS-232 serial port operates up to 38.4 Bps. The GPIB interface is compatible with the IEEE-488.2.



Frequency:

Range: 15 to 1,200 Hz.

Resolution: 4 significant digits, eg. 50.00, 400.0, etc.

Accuracy: ±0.01%, 15 to 1,200 Hz



Voltage:

Range: 0 to Vmax in 0.1 VAC steps.

Accuracy: Executive voltage is within ±50 mVAC (0.05%) of command voltage referenced to the internal voltmeter with CSC engaged.



Phase Angle:

Phase Separation of Phases B and C are programmable 0 to 360° relative to phase A on the UPC-3 controller. Phase separation is fixed at 120° and 240°, respectively, on the UPC-3M controller.



Programmable Current Limit:

Programmable Current limit is provided on the UPC-1 and the UPC-3 controllers. Programmable range is from 0 to Ipeak, max of the power source.

Output Voltmeter:

The Output Voltmeter is true RMS reading and each phase is measured independently. Line to neutral and line to line voltages are displayed. Range: 0-354 VACL-N, 0-708 VACL-L. Resolution: 0.1 VAC to front panel, 0.001 VAC to remote interface. Accuracy: ±0.2% of range + cal. ref.

Output Ammeter:

Output Ammeter is true RMS reading and each phase is measured independently. RMS and peak currents along with Crest factor are displayed. Range: 300% of system current rating. Resolution: 0.01 AAC to front panel, 0.001 AAC to remote interface. Accuracy: ±0.2% of range + cal ref.

Power:

Measures True Power (kW), Apparent Power (kVA) and power factor. Range: Based on ammeter. Resolution: 1.0 watts or VA to front panel, 1.0 watts or VA to remote interface.

Power Factor:

Calculated and displayed to three significant digits.

Pacific’s line of Smartsource® AC Power Sources enable the engineer to easily automate his testing by using Lab VIEW for Windows® or LabWindows®. An extensive list of Virtual Instruments (VIs) are offered for Pacific’s ASX Series Power Sources.
