ZENER TECHNOLOGY AND QUALITY ASSURANCE
Since 1976 Zener Electric has supplied many thousands of drives to industry. These drives have
been installed into numerous applications resulting in a wealth of in house experience. The Zener
MSC-3 AC variable speed controller is the culmination of this experience, modern technology and
industrial application requirements. The Zener Quality Assurance program ensures that every MSC-3
manufactured has proven to operate correctly in the production test bay before dispatch.
SAFETY
Your MSC-3 must be applied, installed and operated in a safe manner. It is the responsibility of the user
to ensure compliance with all regulations and practices covering the installation and wiring of your MSC-
3. The instruction manual should be completely read and understood before attempting to connect or
operate the MSC-3. Only skilled personnel should install this equipment.
This equipment contains a number of components that are designated by their various manufacturers
as “not for use in life support appliances, devices or systems where malfunction of the components can
reasonably be expected to result in personal injury or death”. Customers using or selling Zener products
for use in such applications do so at their own risk and agree to indemnify Zener for any damage
resulting from improper use or sale.

A Zener Drive for Every Application
The ZENER MSC-3 series Variable Speed Drive is suitable for all types of loads, producing greater motor
torque over the full speed range with ZENER’s unique ‘Flux Plus’ control algorithm.
Variable Torque Loads
Typically Pumps and Fans
Constant Torque Loads
Typically Conveyors,
Machines
• Quiet Motor Operation (Audible frequency
adjustable from 2 to 16kHz)
• 110% full overload capacity from
0-200Hz
• Controlled ramp from 0.1 sec to 1min
• Able to start into a high inertia load
rotating at full speed without damage
• PID control for automatic process control
• Energy savings with speed reduction
• Soft Stop to reduce water hammer
problems
• Flux plus for torque maximisation
• 150% - 175% full overload capacity from
0-200Hz
• Automatic Boost and slip compensation
for uctuating loads
• Dynamic Braking for rapid deceleration of
high inertia loads (optional)
• Congurable Analog & Digital I/O
A Zener Drive for Different Environments
ZENER also offers a range of enclosure types to suit different environmental conditions, for improved life
expectancy and reliability. Ratings at 40ºC, 45ºC and a 50ºC rating are available.
IP30 ENCLOSED
Painted enclosure with IP30 rating for mounting within an
enclosure or Switch Board.
Up to 170Amps
IP 54 ENCLOSED
Painted enclosure with a dual compartment, self contained,
forced ventilated IP54 enclosure. All electronic components
are housed in a totally enclosed compartment separate from
the heatsink.
220-490Amp
IP66 ENCLOSED
Painted enclosure with a dual compartment, self-contained,
forced ventilated IP66 enclosure providing added protection
against the ingress of dust and water without the use of
air lters. All electronic components are housed in a totally
enclosed compartment separate from the heatsink and
ventilation fan compartment.
Up to 170Amps
IP66 STAINLESS STEEL
Stainless Steel 304 with a dual compartment, self-contained,
forced ventilated IP66 enclosure providing added protection
against the ingress of dust and water without the use of air
lters. All electronic components are housed in a totally en-
closed compartment separate from the heatsink and ventila-
tion fan compartment.
Up to 140Amps
