These may becaused naturally, by lightning strikes, snow storms and over-grown vegetation or artificially, by heavy load switching, shortcircuits and automatic these interruptions are generally less than one second induration, most industrial installations and plants are able to ridethrough such power dips by virtue of their electrical and me-chanical inertia.

2 This is not the case with electrically held-in con-tactors and relays which control the machinery. These usuallydrop out after a few milliseconds, and as a result, the plant orprocess has to be voltage DIP- PROOFING INVERTER (DPI) offers amaintenance-free solution to facilities that suffer from costly andinconvenient disruption of critical production processes. The DPImaintains AC control voltage to switchboards and motor controlcenters during momentary power dips and voltage sags by sup-plying standby power to such items as contactors, relays, PLCs,and other sensitive devices.

3 No batteries; therefore, no replacement and maintenance costs or hazardous waste. More reliable; ultra-fast (<700 S) transfer, off-line system develops little heat & fails to safety. Able to withstand high inrush currents; no need to oversize as with UPS s & CVT s. Lightweight, small & easy to retrofit; no step-up transformers or batteries. Accurate application control; adjustable ride through time & variable transfer level. Well suited to inductive and low power factor incurred by these power quality problems far outweigh the cost of installing the DPI and investmentpayback is achieved in a relatively short period of time.

9 #112 Bellingham, WA 98226, USAweb: : DescriptionOur range of VOLTAGE-DIP PROOFING Invert-ers offers a low cost maintenance free solu-tion to production line stoppages caused byshort power interruptions. Energy storagecapacitors eliminate the need for batterymaintenance and hazardous INVERTERS can withstand largesurge currents and are therefore ideally suitedfor contactor operation. When specifying aninverter, only the nominal load VA needs tobe considered, in contrast a UPS systemmust be specified for the peak a power factor range of cos from1 to 0 the INVERTERS can supply highly induc-tive loads such as contactors, starters INVERTERS are easy to incorporateduring the manufacture of new switchgearand, due to their small physical size, existingswitchgear can be retrofitted without reliability is inherent in the off linesystem design(MTBF>350,000 Hrs).

10 In addi-tion, only industrial grade materials and com-ponents are used in the manufacturing proc-ess. Rigorous testing is carried out at eachstage of manufacture. Completed invertersundergo a final 100 hour soak test at 113 Fambient to ensure that reliability in the fieldis not compromised. All units are covered bya 36 month design simplifies field servicewhile diagnostic indicators clearly show faultconditions. Optional potential free contactsare available for remote monitoring.
