ELECTRONIC POLARITY-REVERSING CONTROL UNIT
SAV 876.12
With integrated microcontroller and holding force control
Use:
For electro permanent magnet systems with 210 V or
360 V magnet voltage.
Also suitable for subsequent installation.
Operation via hand held control unit SAV 876.02-SE3,
The operating controls are built-in or PLC signals
to the machinery.
Funktion:
- As impulse control for the magnetisation of electro
permanent magnetic chucks
- Control of the demagnetisation cycle
- Optimised for all SAV electro permanent magnetic
chucks
- Monitoring of the mains voltage, the power components and all cables, including the magnet coil.
Some internal components are provided redundantly.
- Machinery enabling via two channel safety contact.
- Clamping and release via redundant input signals
with feedback following magnetisation and demagnetisation.
- Holding force regulation according to inverse BCDcoding, 8- or 16-stage
Features:
- Small and compact
- Easily integrated into any machine
- User-friendly through LCD-plain text display
German/English
- Foil keypad allows easy menu selection
- Signal input and outputs indicated via SMD-LED’s
- Plug for signal input and outputs
- Magnet connection with potential-free switching
- Safe to operate and reliable
- The switching box version has an isolating switch,
terminal block and automatic circuit breaker
Benefits:
- Short-circuit proof
- Fully electronic control and power circuit boards
- Additional potential-free switching relays for magnet connection
- Extended diagnostics
- Earth short circuit test
- Very compact design
- Pre-programmed settings
- Individually programmable
- Short demagnetisation cycle
