Mittelspannungs Solid State Soft Starter

Medium voltage solid state soft starter: The HPMV is a third generation, Medium Voltage, digital Medium voltage motor soft starter, designed for use with standard asynchronous and synchronous motors. This highly sophisticated soft starter ensures smooth, step-less acceleration and deceleration, eliminating current and mechanical shocks on motor and load. The HPMV may be supplied as chassis type or a complete system including Line and/or Bypass Contactors. Addible options are Load Break Switch, Fuses, Motor Protection Relay, etc. Advantages at a Glance : Innovative low voltage test mode - full testing with a small L.V motor using standard built in features Advanced Electronic Potential Transformer utilizing Patent Pending "wireless" fiber-optic firing system Each starter is tested for Partial Discharge (Korona) ensuring long term reliability Power factor capacitors can be connected directly to the upstream contactor Heavy duty design at 50 ambient temperature Reduced inrush current and mechanical shock Third generation microprocessor circuitry Soft, stepless acceleration & deceleration Unique starting & stopping characteristics Sophisticated motor protection package User friendly, easy setting and operation IP30-standard, higher protection by special order Two optional methods of delivery: Chassis type for self assembly or Complete system RS485 Communication with MODBUS, PROFIBUS protocols (others - upon request) Wide 45-65Hz Auto-tracking frequency range combining special software with unique hardware arrangement (designed for Marine, Offshore and Generators operating under continuous frequency variation) Torque and current starting and stopping characteristics. Pump control software. Starting & Stopping : Soft start and soft stop Current limit Torque & Current Control ramps Pump Control characteristics Pulse (kick) start Tacho/encoder feedback (option) Dual Adjust - 2 start/stop characteristics for varying loads, two speed motors, etc. Soft starting, Soft Stopping and Final Torque of an HRVS-DN utilizing our infamous "Pump Control Program" Setting & Supervision: Illuminated LCD with 2 lines, 16 characters each Selectable languages: English, German, French or Spanish The LCD displays motor current, fault description and statistical data Easy setting using six soft-touch keys with default parameters Eight LEDs for a quick status display: Control voltage On-Self Test OK Motor soft starting Motor running Motor soft stopping Motor stopped Test Mode Activated Dual Adjust mode Fault Statistics : Last Starting Period Last Start Maximum Current Total Run Time Number of Starts Last Trip Trip Current Total Number of Trips Historical Trip Event Recorder (10 Event conditions) Control Inputs & Outputs: Control voltage: 110-120, 220-240VAC / 50-60Hz or 110 - 220VDC to be specified Separate inputs for Start, Stop (Emergency) and Soft Stop Two programmable External fault inputs - will stop the motor 2 sec. After the contact closes Aux. Contacts - three C/O relays, 8A, 250V, 2000VA: Immediate Relay - changes position upon start signal, with adjustable On & Off delays. Returns to original position upon Voltage Outage, Fault, Stop signal and Soft stop signal at the end of soft stopping process. It can also be configured as a "Shear-pin Alarm" contact. End of Acceleration Relay - operates upon completion of starting process, with adjustable On delay. Returns to original position upon Voltage outage, Fault, Stop and Soft Stop signals. Fault Relay - can be programmed as: Fault - changes position upon Fault, returns to original position upon Reset. Fault-Fail-Safe - changes position upon control voltage connection, returns upon fault. Typical Applications: Fans and centrifuges Conveyors and monorail systems Pumps, Compressors and Chillers Starting large motors from weak power supply (diesel generators, long supply lines, etc.) Marine & Offshore Applications : Thrusters Cargo Pumps (LNG, LPG, etc.) Water & Ballast pumps Refrigeration compressors Hydraulic pumps & power packs Main Propulsion (Variable Pitch Propellers)
