Overview of our resistor types and designs

RIBBON RESISTORS  JOVYLOAD MPR

Resistor modules of the type MPR are designed for high loads and can be adapted to meet the individual requirements of our clients. The resistor elements are manufactured by using selected stainless steel. For stabilisation and aerodynamic reasons the used resistor ribbons are die-cut in such a way that they by means of spot welding are stable strung together retaining their stabile meandering shape. JOVYATLAS uses this type as rail resistors and compact load banks.

STEEL-GRID FIXED RESISTORS JOVYLOAD HWS

The stainless steel sheets of the steel-grid fixed resistors are die-cut in a meandering shape. This allows the realisation of exactly defined resistance values. Various cutting patterns or slits enable the realisation of different resistance values with equal size of elements. The continuous output power of the grid is 500 W. Spacing rollers between the grids provide for a parallel or serial connection of the individual resistance elements.

STEEL-GRID FIXED RESISTORS JOVYLOAD SPR

Also the stainless steel sheets of the steel-grid fixed resistors SPR series are die-cut in a meander shape. Unlike the HWS series, however, the dimensions of the resistor grids depend on the resistance values specified by the customers. The interconnection is enabled by screw connection. As the steel-grid fixed resistors are manufactured according to customer specifications the
continuous output power of the individual grids is different. At this series we also vary the thickness of the resistance material.

RESISTANCE MODULES  JOVYLOAD WPR

Resistor elements of the WPR series consist of a steel sheet equipped with ceramic carriers, on which a wire winding is applied. With this design we are able to achieve accurate high resistance values within smallest space. A further advantage: coiled elements of the WPR series can be integrated into the modular system of the HWS series. 

TUBE RESISTORS JOVYLOAD WW

Resistors of the type JOVYLOAD WW are wound wire
resistors of copper nickel CuNi44 on a ceramic tube. The
housing is made of galvanised sheet steel. Connecting
cables, terminal boxes or adjustable clips are optional
items. The temperature rise during operation is calculated
with the help of a simulation model in order to be able to
adjust the resistor series optimally to the impulse load.
This enables us to define optimally the resistance for any
impulse shape required by our customers. For higher loads
further tube resistors modules can be combined resulting
in manifold application options for WW-Resistors. The
JOVYLOAD WW series allows an ideal customer- oriented
solution for any application even for smaller quantities.

TUBULAR HEATING ELEMENTS JOVYLOAD RHK

The tubular heating elements of this series provide high
degrees of protection and can be used under difficult
environmental conditions. NiCr 80/20 as resistance wire
ensures a very high accuracy of the resistance value
also during continuous operation. The outer case is
made of stainless steel and guarantees long life.

UPS systems JOVYTEC PM E are available with power ranges of 1000 VA up to 10000 VA.
The transducer systems of the JOVYTEC PME range are used for many applications in maritime
shipping, on the industrial sector and in data processing.

This is due to the high quaility, the extensive equipment and the wide ranging application possibilities. The systems can be set for the most varied requirements via the 5-language menu.

There are systems with 1000, 1500, 2000, 3000 as well as 6000 and 10000 VA. The units with
2000 and 3000 VA are also available as a short version with a depth of 425 mm for for installation
in industrial cabinets. 

The most diverse requirements and areas of application in industry require special designs of UPS systems and require customer-specific adaptations or developments of UPS systems. The production of the industrially used UPS systems JOVYSTAR INDUSTRIE therefore takes place depending on the area of application and requirements.

The customer can determine the installation of additional outlets or additional DC power supplies as well as the cabinet type, the color, the position of additional installations and many other features. Of course, extensive connection options to IT systems or to a central control center are also available for these tailor-made systems. All industrial versions are based on the innovative technology of our JOVYSTAR series.

In the power ranges 10 - 40 kVA, the UPS systems work with IGBT rectifiers (with PFC); in higher power ranges up to 150 kVA, 6-pulse thyristor rectifiers are used.

The modular UPS systems from the JOVYCUBE series are based on a 20kVA UPS module and offer the flexible solution for power supplies from 20kVA up to 640kVA.

The UPS modules impress with efficient power control, dynamic transitions without switching times, and high efficiency of 96%. They have extensive battery management with dynamic charging control. The JOVYCUBE UPS systems can work in both single-phase and three-phase modes.
