The Control is a PID controller that makes any solenoid valve "intelligent", the choice of solenoid valve depending on the user's application (from among the 601, Posiflow, Preciflow solenoid valves etc), and on the installation, which may be in a critical environment.
The Control can control 2 loops in the same manufacturing process, whether they are open, closed or double (cascaded). For instance:
- In an open loop: the Control adjusts the valve's pressure or flow rate (without a sensor) by measuring the feedback value.
- In a closed loop: the Control continuously compares the set pressure or flow with the set point thanks to a signal emitted by the sensor. The benefits? Very precise control (hysteresis of 1%) that reacts to external interference
- In a double loop (with 2 sensors): the first loop adjusts the valve's pressure or flow for optimum control, while the second loop returns the signal of the relevant feedback value (pressure, position, force etc). Because the process's response time is integrated into the control process as a whole, the latter is more stable. |

EFS 8427 IPOD COIL
PRESENTATION
The EFS 8427 rack is a power
driving module for injection
systems that use magnetoelectric
technology.
It features different driving
modes and advanced functions
making it adaptable to most of
the injectors available on the
market.
ADVANTAGES
• Internal power supply adjustable from 6 to 50 V (compatible with the new automobile
systems powered under 42 V)
• Can operate at high voltages of up to 150 V and can generate up to 30 A peak value
• Independent unit with internal pulse generator
• Features functions compatible with the whole range of 823x Ipods
USE
The injector driving parameters can be modified by means of an RS232 or RS485 (4wire)
link, using the MODBUS protocol:
• MODBUS identification on the front panel
• Daisy chaining of racks by means of the RS485 link
• PC supervision software available on demand.
The injector driving can be started:
• by an external input
• by an internal pulse generator.
The driving modes are derived from a basic cycle defined by the following
phases:
• Boost phase (high voltage capacity discharge) as an option
• Pull-in phase (current chopping on thresholds)
• Holding phase (current chopping on thresholds)
• Discharge phase (Zener voltage).
The system is fully protected against overcurrents, short-circuits and overheating.

MAGDOS LT is a solenoid-driven diaphragm pump with a state of the art microprocessor-controlled electronic.
The electronic provides power to the pump drive depending on the system´s pressure requirements thus reducing power consumption, noise level and heat generation. Due to the reduced heat generation MAGDOS LT operates at ambient temperatures of up to 45°C (113°F) depending on the chemical resistance of the wetted end material.
This dosing pump is available for a capacity range of up to 6 l/h and a maximum pressure of 6 to 16 bar. A flexible pressure adjustment is possible.
Double-ball check valves ensure high accuracy even at smallest flow rates.
MAGDOS LT solenoid-driven dosing pumps are especially suitable for water treatment and applications in the process industry. Due to the hermetically sealed design they are suitable for toxic and aggressive media.

Three-phase and neutral line filters are a compact solution for the interference suppression on the mains input of cabinets and control units of equipment, ranging from industrial applications like machine tools to sensitive medical installations. These typically involve separate and often
insufficiently filtered frequency inverters and SMPS, causing current imbalance and significant interference problems. As individual elements they may be interference-suppressed already. The conjunction of several switching components in the same cabinet and a non-EMC conscious cabling will rise the demand for an additional EMC filter on the mains input of the whole installation. Many times this is the only way to get the CE mark for the cabinet in accordance with the EMC directive. |

The conventional output-choke has a very good storage capacity. It functions like a typical series inductance and smoothes the symmetrical, effective current and the asymmetrical, parasitic current. The voltage rise is limited to less than 500 V/µs. The line to line voltage peaks at the motor terminals are lower than 1000 V. This solution attenuates the cable-conducted disturbance really well, even in the lower frequency range. The electromagnetic radiation from cables is attenuated considerably. Losses and typical motor noise, caused by harmonics, are reduced.
