To protect sensitive electronic equipment from the types of line disturbances outlined above, you must determine the precise details of these disturbances and the estimated frequency of their occurrence. Only with this information can an economic choice of the proper power line protective approach be made, based on the specifications of the particular electronic equipment load and the requirements for the assured continuity of operation of this load.
To gain this information requires extended periods of power line monitoring and, frequently, correlation of line disturbances with faults that occur in your computer, peripherals, or other load devices. The Dranetz Series 626 Universal Disturbance Analyzer was designed as a modular, flexible instrument capable of performing any of the functions required for thorough power line disturbance monitoring as well as analysis of many other environmental disturbance parameters.
The microprocessor-based Series 626 can monitor any electrical distribution system up to 600 volts AC. Voltage thresholds are fully user-selectable and setup is fast and easy through front panel keyboards with operator-assistance prompting. A thermal printer provides an English-language hard copy record. Various printout modes are selectable depending upon required detail. A real-time clock keeps track of disturbance timing and duration.
A wide selection of plug-in modules are available for insertion in the Universal Disturbance Analyzer mainframe. Included are modules for monitoring:
Disturbance data can be stored from the Series 626 RS232C communications port by a mass storage module for later transmission to a terminal or printer.
