ELEKTON-05 Variable Speed Drive

Purpose and application

VSD Elekton-05 is used to control/regulate speed and protect industrial three-phase induction motors with squirrel-cage or phase rotor and (or) three-phase PMM motors.

At the customer's request, VSD can be produced with a 6, 12, 18 or 24-pulse input rectifier and with a nominal supply voltage of 415, 435, 480 V and a frequency of 60 Hz. When the supply voltage is different from 380 V and (or) the frequency of the supply voltage is 60 Hz, the electrical characteristics of the VSD are agreed separately.

APPLICATION:

• Induction motors for Electrical Submergible Pumps (ESPs);
• PMM motors for ESPs;
• VSD operated motors for ESPs;
• Induction motors for industry applications – water transfer pump, Progressing Cavity Pumps, smoke sucker and HVAC systems (heating, ventilation and air conditioning) industrial ventilation.

FUNCTIONS

• Stable operation immune to input voltage variations.
• Stabilized output voltage at input power oscillations in case of instability of mains supply.
• Built-in filter to suppress input harmonics.
• Simple and quick maintenance.
• USB-port for data download a standard USB Flash card
• Designed for quick repairs the construction is distinguished for its high degree of repairability.

ADVANTAGES

• Modular design for fast replacement of failed units in the field (without soldering);
• Cable clamps configured for different cable sizes;
• During short-term voltage drops in the mains, the controller uses an emergency mode to operate and record operating parameters;
• Storage pocket for document hard copies ;
• Power consumption meter can optionally be installed;
• Enclosure, removable covers, cabinet doors and locking devices provide reliable protection of internal components, external connection elements and control bodies of the control stations;;
• Protection of power and control electronics from ambient exposure during operation, maintenance and other activities requiring opening the doors of the power compartment;
• Protection of the control station HVAC against dust and moisture;
• The VSD ventilation air ducts are equipped with shutters (for winter/summer operation modes) to prevent atmospheric moisture entering the power and control electronics compartments in adverse weather conditions (snow storms, rain with snow, etc.); ;
• The VSD input/output compartments for junction boxes sizes are protected against ingress of (snow, moisture). The control station design allows easy cables connection and protective elements replacement in the field at ambient temperatures ranging from -60°C to +50°C;
• If required, the design also allows connecting several power cables of different sizes without lugs for output current rating, to the VSD back panel at any ambient conditions;
• 220 V, 10 A socket available;
• Data storage with USB port data download to a standard USB flash card;
• LAN port for Ethernet connection via Modbus TCP protocol.

VSD design allows pump start up following a preset program, in manual and automated mode, as well as to control a required operating parameter (frequency, current, pressure) with a PID controller.
