Elca srl - current rectifiers

ELCA Rectifiers for HARD ANODIZING

The new ELCA current Rectifier digital type

Main functions:
(Programming / SCR firing control and output regulation / Parameter and Alarm Indication / Interfacing with external PC or PLC) are controlled by a fully digital system

ELCA Pulse Rectifiers for HARD ANODIZING:

Pulsating waveform:

Different working modes can be set and different parameters of the pulsating waveform can be adjusted in the same cycle for full flexibility

Stabilization: constant current control with max voltage limit, or constant voltage

Cooling options (alternatively):

- Forced air (IP20)
- Mixed air/water (Protection degree IP20)
- Water cooling (IP54)

Standard sizes:

- Standard rectifier size from 300 Adc to 10.000 Adc
- Output voltage from 0 to 100 Vdc
Different sizes on request

Control Options:

- ELCA RAMPER Process Computer to carry out automatically the anodizing process

- Full interface to external PLC
