COST EFFECTIVE IMBEDDED POWER MONITOR

摘要

Imbedding an Ethernet connected web-based low-cost power monitor into a permanentlyrninstalled Original Equipment Manufacturer's (OEM) 3-phase power subsystem gives the user thernability to monitor their sites 24×7×365. As compared to the more traditional temporary powerrnmonitoring for OEMs, having a monitor permanently installed at each site can help preventrncostly and repetitive site problems by identifying if the AC power is related to a specific siternproblem anytime. To make an imbedded power monitor solution feasible, the device must bernlow cost, and to capture typical power quality events, it must be high performance.rnTEAL Electronics is introducing the TEALwatch? power monitor, a low-cost imbedded powerrnmonitor utilizing a web based interface for remote monitoring capability. The TEALwatch? isrndesigned to be integrated into a 3-phase power subsystem, monitoring the mains voltage at thernpower entry point for the OEM equipment such as Semiconductor Automated Test or MedicalrnImaging equipment. The monitoring interface is Ethernet 10base-T, enabling remote monitoringrnwith a simple web browser from any Internet connected PC, with no special software required.rnThe TEALwatch? features programmable triggering parameters and has built-in non-volatilernstorage for multiple waveforms captured on triggered events with 128 samples per cyclernresolution.
