587E - Voltage and Current Surge Generator
The Velonex 587E Solid State Voltage and Current Surge Generator provides the waveshapes and characteristics that meet and exceed those required by IEEE/ANSI C62.41-1991 and lEC 801-5. These standards describe surge testing requirements in low voltage AC power circuits, and for transient voltage supressors. The Model 587E performance specifications apply when operating with or without a Model V-2980 Coupler Isolation Network or equivalent.
V-2980 Programmable, Single-Phase Isolation Unit
The Velonex V-2980 single-phase isolation unit allows surge testing of devices or equipment connected to active single-phase power lines up to 277V RIM and 25A (30A intermittent). The isolation unit will protect the power line from undesirable back surges without loading the surge generator output and will attenuate the AC voltage being fed back into the generator. The V-2980 is used in conjunction with the Velonex Models 587, 588 or 590 Voltage and Current Surge Generators to form a complete surge testing system.
The Model V-2980 allows for fast change and bit programmabilty of the surge polarity and coupling modes. The V-2980 has also been designed and specified for low backswing (undershoot). A Model V-2627 GPIB Interface Adaptor is available to provide IEEE 488 bus capability.
The Model V-2980 allows for four different switch selectable surge injection methods, consisting of one normal mode and three common mode tests. Polarity switch selection is standard, allowing for comprehensive testing of equipment under all line surge conditions.
The Model V-2980 accepts a full line of NEMA single-phase receptacles as plug-in units. Also provided is a differential high voltage attenuator to allow direct connection of an oscilloscope for monitoring surge events.
