The M-2054 Surface Mount Kit, used in conjunction with the M-2001

Series Digital Tapchanger Control, uses modern electronic digital

design and digital processing circuitry to achieve an overall stability

and resolution unattainable with electromechanical and analog design

tapchanger controls.

Voltage waveform sampling and digital processing circuitry ensure 

accurate rms voltage sensing in the presence of distortion on the input

voltage and current.

Accuracy exceeds the ANSI/IEEE C57.15-1986 Class 1 specification over

the temperature range of -40° C to +80° C.

Input and output circuits are protected against system transients.

Units pass all requirements of ANSI/IEEE C37.90.1- 1989. which defines

surge withstand capability.

All input and output terminals will withstand 1500 V ac rms to chassis or

instrument ground for one minute with a leakage current not to exceed

25 mA, for all terminals to ground. Input and output circuits are electrically

isolated from each other, from other circuits and from ground.

A voltage sensing fuse and a spare fuse are provided.
