Filter Protective Devices 4983-PF and 4983-DC • Bulletin 4983-PF and 4983-DC filter protective devices address low-level voltage transients and high-frequency noise disturbances that, over time, cause premature aging. • The long term effects of noise are just as damaging as high voltage transients. • The 4983-PF and 4983-DC devices feature Islatrol filter technology. • Islatrol filter technology continually tracks and monitors the input signal to provide clean and reliable AC power for critical equipment. • Bulletin 4983-PF and 4983-DC filters are connected in series. Protection is best when the devices are installed directly in front of the load requiring protection. • Typical applications include any microprocessor based products such as PLCs, motion control systems, and computers exposed to harsh environments. 4983-PF • Filter for low-level transients and high-frequency noise • UL 1283, CSA, CE • Features Islatrol® filter technology • LED power indication • Panel (flange) mount 4983-DC • UL 1449 Third Edition, UL 1283, CE • Small combination (filter and SPD) package size • Features Islatrol filter technology • LED power indication • Form C contact for remote status indication
