AC fans based on Electronically Commutated motors – also called EC fans – differentiate from previous AC fans with its optimal level of price and performance. These fans are more economical to operate than previous AC fans thanks to their lower power dissipation. They also have a high motor efficiency in the partial load range. Instead of shaded motors, they are based on BLDC motors, with integrated commutation electronics generating the rotating field of the motor. The connection is made directly to the AC mains. The optimized design of the motor and electronics ensures a low drive noise. Nidec Servo's FP series of axial fans are based on EC motors and have been specially developed for commercial air conditioning and refrigeration systems with high requirements in terms of efficiency, reliability and noise emission. The fans are preferably suitable for use in refrigerated display cases, refrigerated shelves or chest freezers, which are used, for example, in supermarkets. Other successful high duty applications include self-service refrigerated counters, cold stores and small cold stores, beverage refrigerators, vending machines, ice machines and wet rooms such as bathrooms and kitchens. The ball-bearing fans have a universal voltage range between 115 and 230 V/AC and an efficiency of up to 70 percent compared to conventional fans. They are water-protected according to IP67. The air flow rate is up to 350 CFM. The speed is adjustable from 800 to 2100 revolutions. The fans can be used at ambient temperatures between -40 °C and 55 °C. They have several approvals such as UL and according to ATEX directives 94/9/EC EN60079-31.

EtherCAT-P is a further development of the worldwide established EtherCAT technology. The special feature of EtherCAT-P is the combination of the super-fast EtherCAT communication with the 24 V power supply. Data and power (Us) for system and sensor supply with 24 V and 3 A are provided on a two-wire pair.
A second pair of wires provides data and the peripheral voltage (Up) for supplying the actuators. The direct coupling of the supply voltage to the 100 Mbit line enables a compact and cost-effective device connection. CONEC currently offers shielded axial overmoulded designs with cable quality G6, TPU 4xAWG22, available in standard lengths. For the 100 MBit device connection almost exclusively male-male patch cords are used. Field attachable connectors are available as female and male variants in axial design, either with screw (female and male connector) or crimp (male connector) termination. Flanges for direct PCB mounting are available for the device connection.
The continuous shielding from the flange housing to the circuit board is realized with a punched sheet metal plate. Moulded contact tongues form the radial connection to the flange housing. A special flange version with moulded cable and a further plug on side B, preferably P-coded, is suitable for wiring through the wall of a switch cabinet, for example. ▪ ds
