150 251-05 U554 Camille Bauer Metrawatt AG

Product Information

The SINEAX U554 is a transducer designed for AC voltage measurement. It has different characteristics and options for voltage transfer. It is manufactured by Camille Bauer Metrawatt AG, a company based in Switzerland.

Product instruction

Before operating the SINEAX U554, read the operating

1. instructions carefully.
2. Ensure that all electrical connections are made according to the specifications provided on the transducer’s label. Make sure that all connections are free from voltage before proceeding.
3. Pay attention to the maximum and minimum input voltage ranges. Do not exceed these limits.
4. For power supply, connect either to the low voltage side (24 V AC or 24-60 V DC) or use self-powering by connecting to the Messeingang (24-60 V AC or 85-230 V AC).
5. Mount the SINEAX U554 on a Hutschiene (DIN rail) using appropriate mounting methods.
6. Once installed, the transducer is maintenance-free and does not require any further servicing.

Read first and then …

The proper and safe operation of the device assumes that the Operating Instructions is read carefully and the safety warnings given in the various Sections

• Mounting
• Electrical connections are observed.

The device should only be handled by appropriately trained personnel who are familiar with it and authorised to work in electrical installations.
Unauthorized repair or alteration of the unit invalidates the warranty.

Brief description

The SINEAX U 554 measuring transducer is used to convert a sine-wave or distorted AC voltage.
The output signal, in the form of a load independent DC current or voltage, is proportional to the measured value.

Indoor use statement!

Mounting

The SINEAX U554 can be mounted on a top-hat rail.
Note “Enironmental conditions” in Section “3. Technical data” when determining the place of installation!
Simply clip the device onto the top-hat rail (EN 50022) (see Fig. 1).

Fig. 1. Mounting onto top-hat rail 35 × 15 or 35 × 7.5 mm.

Electrical connections

Connect the electrical conductors acc. to the instructions on type label. Make sure that all input cables are not live (potential-free) when making the connections!Impending danger by high input voltage or high power supply voltage! Also note that, …
… the data required to carry out the prescribed measurement must correspond to those mar-ked on the nameplate of the SINEAX U554  measuring input, measuring output  power supply, ****see Fig. 5)! … the resistance in the output circuit may not overage the current output value

… the measurement output cables should be twisted pairs and run as far as possible away from heavy current cables! In all other respects, observe all local regulations when selecting the type of electrical cable and installing them!

 Commissioning and maintenance

Switch on the power supply and the measuring input. It is possible during the operation to disconnect the output line and to connect a check instrument, e.g for a functional test.
No maintenance is required.

Releasing the transducer

Release the transducer from a top-hat rail as shown in Fig. 6.
