ADVANTAGES AT GLANCE
Rugged Design - Rated at 50°C ambient temperature
Reduce Inrush Current - And mechanical shock
Advanced Control - Based on third generation
microprocessor circuitry
Soft, Stepless Acceleration & Deceleration
Flexible - Multiple starting & stopping modes
Complete motor protection package
User-Friendly - Easy setting and operation
Safe Low Voltage / No Voltage Test Modes - Full
testing with a small L.V motor using standard built in
features and “dry” cabinet automation test
Reliable - Each starter is tested for Partial Discharge
(Korona) according to EN50178/625.1
FOR EVERY NEW BEGINNING YOU NEED A GOOD START.
This third generation, micro-processor controlled through fiber optic links, Medium Voltage soft starter is designed
for use with standard asynchronous and synchronous motors. The OPAL-MV is a highly sophisticated digital soft
starter which ensures smooth, stepless acceleration and deceleration, eliminating current and mechanical shocks on
motor and load. The OPAL-MV may be supplied as a chassis or enclosed type with a multiple range of options.
"For Every New Beginning

UNIQUE FEATURES
Wireless Electronic Potential Transformer (EPT) -
The advanced electronic potential transformer utilizes the
patent pending “wireless” voltage measurement system
reducing space and installation costs.
Fiber-Optic Firing System - Fiber-optic firing system
provides complete isolation between MV and LV
compartments.
Direct Power Factor Capacitor Connection - Power
factor capacitors can be connected directly to the upstream
contactor, omitting the need for an additional contactor.
Multi-Motor Starting - Multi-Motor program allows for more
than one motor to be used with the same soft starter.
Multi-Voltage Starters - Dual-Voltage connection permits
more than one voltage level to be used with the same soft
starter.
Fault Indication - Unique fault indication to the individual
thyristor level
Communications - RS485 Communication with MODBUS,
PROFIBUS or MODBUS/TCP protocols (others - upon
request)
Auto-Tracking Frequency Range - Wide 45-65Hz Auto-
tracking frequency range combining special software with
unique hardware arrangement.
