1. Application
The transducers EURAX UI 505 (Figs. 1 and 2) are intended
to simultaneous converts of up to 3 sinusoidal AC currents
or voltages. Output signals available are load-independent
DC currents proportional to the measured quantity.
2. Features / Benefits
● Up to 3 measuring inputs: AC currents and/or AC voltages, sine
wave-form, arithmetical mean measured, calibration to RMS
value
Measured variables
AC currents
AC voltages
● Up to 3 measuring outputs: DC current signal (load-independent)
or DC voltage signal
● Self-powered / Less wiring expense
● Low power consumption / Smaller CT's and VT's can be used
● Manufactured in SMD technology / Compact and reliable
● Laser trimmed / Virtually no accuracy variation between units
● The device fulfils the protection requirements of the EMC guide-
lines (89/336/EWG). The device bears the CE symbol for EMC
● Mechanical design of the transducer: Plug-in module 7 TE
(35.2 mm) for 19" rack-mounted case
Measuring range limits
0 ... 0.5 to 0 ... 10 A
0 ... 20 to 0 ... 660 V

3. Layout and mode of operation

The transducer consists of one PCB containing - depending
on type and duty - 1 to 3 transducers working independently
one from another.
Arranged on the front plate are the grip, inscription and on
request test sockets for field indicator. On the back of the
module is a DIN 41 612 F plug. For connecting to current
transformers there is a special shorting triplug available (for
description see data sheet BT 901 Le).
