The ZSM is a electronics ignition device for the excitation system of AvK DSU generators. EMRI supplies the DSU module as well as the DSU Thyristors and Diodes. Cummins Ingolstad, long time producer of the ZSM module, disconinued this product.
The Dual Channel AVR is used to create a redundant AVR system for synchronous generators. Upon a system fault the faulty AVR is isolated from the system and the redundant AVR is put into operation.
The CAN Bus provides digital access to the main root cause of the fault and possible remedy. Manual switch back to the repaired / exchanged primary AVR.
Diode failure detection. Unit which monitors the condition of the AVR current to determine defective diodes and avoids successive damage as a result of exciter problems.
Fully encapsulated low cost, rugged and reliable, easy to apply voltage regulator for single operating generators in the range up to approx. 150 kVA. Single phase sensing. 115Volt or 230 Volt range sensing, 50-60 Hertz. Direct fit for Stamford SX460 AVR
Powerful automatic voltage regulator with adjustable PI parameter. Suitable for separate sensing and supply voltages. Reactive current sharing for parallel operation. Completely encapsulated for protection against environmental influences. fits for Stamford SX440 AVR.
Automatic voltage regulator for generators operated under adverse conditions, such as truck-mounted generators. The special digital protections, which are integrated, protect the prime mover, generator and installation. Automotive certified. A CAN bus interface for reading and setting of variables is integrated.
The most universal and widely applicable automatic voltage regulator for retrofits in numerous brands and types of generators, thanks to it’s unique concept and wide supply and sensing ranges. Every generator servicing company should have this product to re-excite almost any generator. 
Universal and Leroy Somer compatible Digital automatic voltage regulator with various control modes and integrated protections. Motor start, power factor control, full-scale range control, current limitation functions are integrated. CAN bus interface for communication. PUR potted product to protect against environmental influences. Available in inverted mode (MCR440PH and ARES) and diverted mode (Leroy Somer).
Automatic voltage regulator for lager size brushless geneators (1000 rpm and less) with higher excitation values or lower exciter stator resistances. Variable supply voltages make it suitable for a wide range of applications.
