Output components for motor protection and the improvement of system reliability, availability and functionality. Deployed at the output side of frequency inverters, these filters ensure reliable operation by avoiding expensive downtimes of installations, manufacturing plants, machinery and
a vast array of other industrial and domestic motor drive applications due to premature motor damage. An appropriate output solution will even allow the deployment of unshielded motor cables, the use of multiple motors in parallel on the same drive or the retrofit of modern drives in existing installations with old motors and unshielded cabling.

EMC Technique
EMC is an important factor for the operational reliability in machinery and plants and ensured the compliance with valid norms and standards.
European norms and standards require manufacturers and users to comply with a set of EMC limitations.
KEB designs, manufactures and supplies a comprehensive range of input/output filters and chokes to comply with all international standards as well as to improve operating conditions.
KEB experts in the field of EMC offer advice and support during the selection process of suitable products. For on-site testing a mobile EMC service is available.
Competent consultation and mobile EMC-measuring means provide the options and optimisation on location - in short - they save in different uses the dependable compliance of the monetary requirements.

Solid State Relay with phase angle control output
In a new and high-performance IP20 housing to the size of a standard “hockey puck” relay, this phase angle power SSR makes the voltage output vary with the analogue input voltage. Consequently the power applied to the load is proportional to the input. More precisely, thanks to the control logic performed by a micro-processor, power is a linear function of the input (proportional to U²).
In this small housing, the new series of relays switches from 35 Amps to 125 Amps. The standard output cage terminals can accept 2 AWG8 wires for currents up to 2 x 50 Amps or AWG0 wires thanks to a special adaptor kit allowing up to 151 Amps!
Products are available with a 4 to 20 mA, 0 to 10 VDC or potentiometer inputs.
In addition, the relay output is protected against transient over- voltages with a varistor, whilst the input/output isolation and input to baseplate isolation or output to baseplate isolation is 4 kV complying with the EN60950/VDE0805.
This new generation of proportional controllers comes also in “celpac” housing (ready to use – 22,5mm pitch).

The range of REOVIB System 500 modules comprises phase-angle controllers for vib-ratory feeders and a timer module used with systems that have track control.
The REOVIB 506 is designed for controlling bowl or linear feeders up to 2A current rating. The output frequency 50Hz/100Hz (60Hz/120Hz) is selected to suit the feeder. In the regulation circuit there is built-in compensation for mains variations. The set-point for the feed rate is derived from a potentiometer and the set-point range can be linearised by using two trimmers Umin/Umax. Furthermore, an enable input is provided for start/stop operation. Fixings are provided for rail mounting to DIN EN 50022-35.

The RM 220E regulator is an electronic speed variator for the MINI MOTOR single-phase asynchronous motor of the ACR / ACER / PAR / PAER / MCR / MCER series. Speed variation is obtained by varying the power supply voltage to the motor at the right moment. The retroaction control makes it possible to maintain a constant rotation speed of the motor in line with the variation of the load applied. Speed regulation is obtained by means of a potentiometer fitted on the front panel of the unit, and 4 incorporated trimmers are used for regulating: The acceleration and deceleration ramps, the response time and maximum speed, and master or slave selection. This speed regulator can be supplied in the RM 220E panel version with the possibility of inserting an ID speed indicator as an option. It is also available in the open version RM 220E/G for electrical board or cabinet fitting. The RM 220E regulator conforms to tests prescribed by product standard CEI EN 61800-3 dated 09/96 and has been designed to operate in industrial environments. It is not therefore suitable for use on low-voltage public networks supplying power to homes.

The MININVERT 370 and 740 are static frequency converters with PWM microprocessor system, which make it possible to obtain high performance features such as speed control in retroaction and position control. These models have been designed to activate small three-phase motors with power between 10 and 370 W (½ HP) for the 370 model, and up to 740 W (1 HP) for the 740 model. They can be panel-mounted as well as with the normal attachment inside the cabinet using the
related supports. A particular feature is that of position control, which is handled entirely by the inverter and can be controlled in various ways (see the table of technical characteristics). The frequency converters comply with CEI EN 61800-3 electromagnetic compatibility standard.
