Our Mission
The mission of JVL Industri Elektronik A/S is exclusively to help our customers to build better, faster and more reliable machines.

Our Goals
Our goal is to apply the latest technology in order to develop and produce the best, most user-friendly and most economical products of the highest quality.

Our Vision
It is our vision to be a preferred and competent partner for leading machine builders all over the world.

Product Program
The up-to-date development, research and production facilities of JVL employ only the latest technology for the development and production of electronic controls for step- and servo motors. More than 50% of the staff are engineers with a very high degree of experience and competence in the field of motion control. They are all highly motivated and innovative, and we can therefore offer a product programme today that includes all the necessary units and components to build up complete motor control systems.

JVL first gained its high reputation in the 80´s for its development of modern, compact step-motor drivers and controllers. In the 90´s this successful development was followed by a series of second-to-none AC and DC servo controllers, which led to marketing of the unique integrated AC servo motor, the MAC motor, (up to 3000W), and the QuickStep, integrated stepper motor (up to 25Nm) which both include the entire controller, encoder etc. in one compact unit.

System Development
In addition to the standard product programme, JVL enjoys a high reputation for development of specialised, customised equipment. This makes it possible for our customers to solve a broad range of control tasks that cannot be directly catered for using units from the standard product range. Our expertise in such development has given us much insight into finding the optimum solution to complex control problems, and has helped many customers to find an economic, yet technically advanced solution to a complicated control application.

Experience and customer support
JVL has more than 20 years of experience in motion control, and our engineers regard it as an important and exciting challenge to work together with customers and representatives to find the optimum solution to each motion control task.

JVL offers a wide selection of quality products for motion control:

Integrated AC-Servo motors

Integrated Stepper motors

AC-Servo motor controllers
DC-Servo motor controllers
Motor drivers, Step-, AC- and DC
Keyboard/Display-, Input/Output- and Counter Modules

Furthermore: Development of customer-specified products. System development. Dimensioning of systems. Engineering consultancy

Marketing
JVL products are marketed all over the world, in Europe, the USA and Asia, by independent representatives who are, carefully selected by JVL to have the necessary knowledge and experience, in order to help our customers in the best possible way in their choice of motion control components.

JVL is represented in the following countries:

In Germany and Great Britain/Ireland by our own companies, JVL Deutschland and JVL UK respectively.

Plus our newest addition "JVL Entegre Motorları Ltd. Şti." in Turkey

In USA and overseas we are represented through our company JVL International.

Belgium	Portugal
China	Singapore
France	Spain
Germany	Sweden
Iceland	Switzerland
Ireland	The Netherlands
Italy	United Kingdom
Korea (KR)
Norway

We are constantly looking for suitable representatives in all other markets, and are in the process of signing contracts with several recognized companies around the world.

70 to 80% of the equipment produced by JVL is exported and a large part is in use outside Denmark, as an integral part of equipment exported by JVL’s Danish customers.

The Customers
JVL´s customers are mainly machine builders, either independent companies or the process machinery departments of larger concerns. A proportion of customers are also found within the education sector and research laboratories.

Many customers also use JVL equipment as a part of their own production which is then sold globally. Among the customers are some of the biggest and internationally most acknowledged companies, including:

Management
JVL Industri Elektronik A/S is managed by the two founders, Bo Valeur Jessen, Technical Director, and Mads Vernon Jørgensen, Managing Director.

The company was founded in 1986 on the basis of the first innovative driver and controller designs, and JVL’s use of the, at that time, latest microprocessor technology. Turnover increased rapidly, and soon JVL took over another well-known and respected Danish company in the field of motor control. This added increased experience to JVL Industri Elektronik’s expertise in the field of motion control, and afforded new possibilities for strengthening the company’s market position.

The company is situated in 1500 m2 premises in an attractive industrial area in the town of Birkerød, north of Copenhagen, offering very good possibilities for future expansion.

The number of employees has steadily increased, and now includes expertise within all the required fields for development and production of motor control equipment.

Ownership
JVL Industri Elektronik A/S is owned exclusively by the two founders. There is no external capital and the company has continued to be self-financing, so that no loans have been incurred apart from that necessary for the daily running of the company. This gives a high degree of freedom in all respects and guarantees JVL’s basis for continued expansion.

Production
JVL’s production uses external suppliers to a large extent, so that the company can concentrate on inspection, final mounting and test. ISO 9000 requirements for quality assurance are widely followed and certification is planned as soon as all procedures have been documented. Computer testing is widely used, and all new designs are tested to ensure that they can withstand the environmental conditions in which they have to work in practical use.

New Developments
At JVL we pay very high attention to, and use a very large part of the budget on, the continuing development and improvement of the product range we offer our customers for motion control.

We are constantly following the trends on the markets and listening to the wishes of our customers. Amongst other things, this attentive approach to the needs of the market has led to the development of unique set-up software with automatic updating of firmware via the internet, and to extended use of Profibus, CANopen, Devicenet, Ethernet and wireless systems With a control system from JVL you are sure to be at the forefront of motion control technology.

JVL awards

JVL has received several awards during the years. Among others from Dun & Bradstreet and Experian (KOB and RKI) for the highest credit rating on the triple-A scale and 5 stars scale. These ratings are awarded on the basis of an overall evaluation of a company´s payment history.

Power Supplies PSU48/12-2

nnnn

and PSU48/24-2

nnnn

12VDC to 48VDC and 24 to 48VDC, 144W, 400W

nnnn

This Power Supply can be used when

nnnn

the supply voltage is 12VDC as for

nnnn

instance a battery. It converts 12

nnnn

VDC to 48VDC regulated so that a

nnnn

motorcontroller which has to be

nnnn

supplied with 48VDC can be connected

nnnn

directly. For instance can the MAC

nnnn

motor MAC050 to MAC141 series

nnnn

and the Quickstep MIS23x series be

nnnn

connected directly. It is possible to

nnnn

connect 12 VDC to a motor controller

nnnn

but the max. velocity will be limited to

nnnn

approximately 25% and the dynamic

nnnn

capabilities of the motor is decreased

nnnn

considerably.

nnnn

PSU48/12-2 can deliver 140W

nnnn

continously and up to 400W peak

nnnn

which matches the requirements of

nnnn

MAC140, which demands 400W in

nnnn

peak. Thereby a reliable and highly

nnnn

dynamic motor system is secured

nnnn

from only a 12VDC supply. If the

nnnn

supply voltage is 24VDC the converter

nnnn

PSU48/24-2 can be delivered.

nnnn

It is recommended to mount a

nnnn

capacitor, for instance 4700|jF/50 volt

nnnn

across the 48V if large peak currents

nnnn

have to be drawn for instance if a

nnnn

MAC140 or MAC141 is used. Thereby

nnnn

the voltage is smoothed out and

nnnn

overshoot that can damage the motor

nnnn

is avoided.

nnnn

Warning: To be installed and

nnnn

connected by qualified personnel only.

nnnn

Ensure all power sources are

nnnn

disconnected when making any

nnnn

connections to this unit.

nnnn

Note: Units are modified to handle

nnnn

high power output for short periods

nnnn

of time. Fuse input and output

nnnn

appropriately. Also, units must be

nnnn

sufficiently heat sunk to dissipate

nnnn

heat. Failure to do so will result in

nnnn

damage.
