1 DELIVERY CHECK

When receiving the unit, check that no damage is visible and its compliance with your requirements. To

do that, refer to the plate (see following figure) located on the converter front side. If the unit is damaged,

contact the insurance company or the supplier.

If the unit is stored before it is used, check that the storage area conditions are acceptable (temperatures

ranging from -20°C and +60°C, relative humidity lower than 95% and no dew).

The warranty covers any manufacturing faults. The manufacturer has no responsibility for damages

occurred during transportation or unpacking.

In no case and in no circumstances, the manufacturer will be responsible for damages or failures due to

wrong usage, abuse, wrong installation or incorrect temperature, humidity or corrosive materials, as well

as for faults caused by operation exceeding the rated values. The manufacturer will not be responsible for

consequential or accidental damages.

The manufacturer provides a 12-month warranty, starting from the delivery date.

1.1 NAMEPLATE

KEY

1. The device is called DCREG4.350. It is an AC/DC digital-operated drive.

2. The device main P/N and size P/N are detailed before and after a full stop respectively

(ELETTRONICA SANTERNO P/Ns).

3. The acronym identifies the configuration consisting of two full-control three-phase bridges in

antiparallel forming the drive power section.

4. The armature section can be supplied with a 500 Vac (max.) three-phase alternate voltage and

according to a 50/60 Hz frequency value, thus absorbing at rated load a three-phase alternate current

equal to 287 A.

5. The field section may be supplied with a single-phase alternate voltage equal to 200 … 500V ac and

according to a 50/60 Hz frequencyvalue, thus absorbing at rated load an alternate current equal to 15 A.

6. The control section may be supplied either with 380 … 500 Vac single-phase alternate voltage or with

a 24 Vdc direct voltage (considering, of course, a different terminal pair).

7. The device is able to supply 520 Vdc (max.) on the armature output, with continuous supply of 350 A

(with a maximum overload of 150 % of the nominal value at a preset duty-cycle).

8. The device is able to supply 425 Vdc (max.) on the field output, with a continuous supply of 1 5A.
