Slip Ring Motor Starter
Magnastart
Magnastart is a unique Inducer system for starting slipring induction motors, offering considerable improvements in maintenance, reliability and cost-effectiveness. Magnastart is used extensively both as a component in new equipment and as a quick and effective replacement for existing resistance and liquid starters. Wide flexibility of tappings allow the impedance to be matched on commissioning. Magnastart has been used with crushers, pumps, fans, conveyers, cranes, mills and presses.
Magnastart Features
- Size: Though physically smaller than conventional systems of resistors and contactors, the large thermal capacity of Magnastart permits the starting of difficult and high inertia loads without problems
- Simplicity: Magnastart requires only one shorting contactor, reducing the system complexity, size and cost
- Performance: Magnastart is ideal for inching, reversing, and plug braking without any additional rotor controls
- Maintenance: Magnastart Inducers have no moving parts, and do not use liquids or chemicals. Magnastart will give many years of service without any maintenance or adjustment
- Reliability: The robust construction permits heavy usage under the most arduous conditions. Built-in thermal cut-out provides protection against damage

Providing both quality and experience the Setzermann division of REO INDUCTIVE COMPONENTS AG produces toroidal current-transformers from with power ratings from 10 VA up to 500 VA. These are available in either standard or custom designs, built to specification and proved in our own test laboratory. The toroidal current-transformers conform to all relevant standards whilst double-isolation and the use of UL approved encapsulation materials are always incorporated in their design. The Setzermann range of current-transformers includes many different styles from those for pcb-mounting to panel-mounting types. We offer our customers a prototyping service before commitment to a final design. Details of all products can be downloaded from our website. Setzermann current-transformers have a good reputation for high-protection and longevity.

Safety transformers of the series TS TSF are particularly indicated to power the temperature monitors and temperature controllers designed for a supply-voltage of 12 Vac.
They get produced in "closed manufacturing", with a plastic box provided of mounting lugs to permit a quick mounting; the electrical connections get done through screw connectors.
TS TSF B and TS TSF D are produced according to EN 60742 norm and defined "safety-transformers", that is why they can fit applications for very low safety voltage on the secondary circuit and for high insulation voltage between the primary circuit and the secondary one.
The protection from short-circuits and overloads is guaranteed for the TS TSF D through an incorporated non self-resetting thermal cut-out, while TS TSF B needs the insertion of a external fusible with the indicated characteristics.

We offer numerous Power Transformers in the toroidal design. For your convenience, we have added the expected DC output, should the transformer be rectified.
The DC output is calculated with a standard full-wave bridge rectifier with a large capacitor. Any of these primaries can be easily used to configure custom secondaries at a reduced cost compared to a full custom design.

Description
You need to be careful when introducing shore power on board, for safety reasons and to protect your yacht, especially if she is made of aluminium or steel. An inadequate configuration of your on board system can result in electrolysis, leading to slow but sure corrosion of the metal components. A Mastervolt isolation transformer will help preserve your valuable boat and provide you with security through a correctly earthed AC power system.
The Mass GI is an extremely small and light (only 5.5 kg) isolation transformer supplied with the latest high-frequency electronics switch technology. Suitable for 120 V and 230 V AC systems, its capacity of 16 A/3.5 kVA per unit can be parallel coupled for higher capacity. Two 16 A/3.5 kVA units correspond to 32 A/7 kVA. This isolation transformer can be fitted in any position on a wall or floor. No rubber mountings are necessary because it does not vibrate or hum. The integrated Soft Start manages the current resulting from connection to the shore.

The traditional products made by REO are grouped under the name of Classics. New developments of these existing products are no longer possible because we always come back to the old and well tried methods. True to the company slogan 'Innovation from Tradition' REO INDUCTIVE COMPONENTS AG is still able to offer to customers a complete range of components for adjusting voltage, current and resistance. Whether is a fixed or variable transformer, toroidal or tubular our products are still suitable for today's industrial environment. The demand is falling for products such as fixed or variable resistors (rheostats), with motor drive or connected in series, and so the manufacturing of these products is becoming more cost-intensive. Therefore by using our engineering, production and selling competences we are able to offer modern equivalents, with higher dynamic characteristics and the same level of quality. REO will remain committed to manufacturing these products for as long as there is still a need for them.
