The Beckwith Electric M-2051/M-2502 Connection Harness, 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. CMOS

semiconductors are used throughout the design. Standard Features

The M-2051/M-2502 Connection Harness, with the M-2001 Series Digital

Tapchanger Control, provides a solid-state voltage control relay intended

for applications involving the control of tapchanging transformers and

regulators.

Features

• 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° to + 80° Celsius.

• 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.

• The M-2051/M-2052 is a general purpose connection harness that is

designed to be mounted on a panel.
