페이지 인쇄Brief description
The ES20/ES220 are panel mounting instruments for monitoring
AC systems with dimensions 96 x 96 mm (ES20) and 44 x 44 mm
(ES220). The following measurements are acquired: voltages, currents,
frequency, and phase angles in single phase or 3 phase systems. From
these, the active power, reactive power, apparent power, active energy,
reactive energy, and the power factor and the neutral current can be cal-
culated. With the use of voltage and current transformers, the instrument
can be used for measurements in medium and high voltage systems.
The transformation ratios are configurable for the direct display of all
measurements. The ES20/ES220 instrument is used as a display with
two S0 pulse or limit value outputs.

Pulse/Limit value outputs
Depending on the function selected, the two digital outputs can be used
either as pulse outputs for active and reactive energy or as limit signals.
The outputs are passive, and are galvanically isolated from all the other
circuits by opto-couplers. They are suitable to drive tariff devices (S0-
standard DIN 43 864) or 24 V-relais.

Impulse outputs
Active and reactive energy impulses can be generated for driving elec-
tronic and electromechanical energy meters.
