SAF OPAL MV User Manual

OPAL MV APPLICATIONS

Industrial

- Pumps

- Compressors and Chillers

- Fans, Blowers, Centrifuges

- Conveyors, elevators, and Monorail systems

- Tachometer driven systems

- Starting from weak power supply (diesel generators,
long supply lines etc)

Marine, Offshore, Oil & Gas

- LNG & LPG pumps (mainly in multi-start application)

- Water & ballast pumps

- Refrigeration chillers & compressors

- Hydraulic pumps & power packs

- Thrusters

- Main propulsion motors

- Unique protection for corrosive environments

- Generator ready - auto frequency tracking, sustains
variations of 45-65Hz while starting

OPAL MV

Medium Voltage Digital Soft Starter 60-2200A, 1500-15000V

Application Specific Software

Starting From Diesel Generator

Wide 45-66 Hz auto-tracking frequency to overcome voltage and frequency instability. Designed especially for marine and off-shore industries, or
any system operating from a generator.

Synchronous Motor Starting

Optional module allows you to utilize your existing synchronous motor.

Pump and Special Load Control

Eliminate Water Hammer During Stopping: The pump control feature enables selection between
three voltage ramp-down curves or a torque curve, preventing a stall condition which eliminates water
hammer.

Eliminate Over Pressure During Starting: The pump control also enables selection between three
voltage ramp-up curves, as well as a torque curve, to reduce peak torque. Current ramp is available
for special loads.

OPAL MV

Medium Voltage Digital Soft Starter 60-2200A, 1500-15000V

"For Every New Beginning
You Need A Good Start.”

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.

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

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.
