Product catalog summary
Overview: The THYRIDIN AT90 series by JOVYATLAS is a robust and widely used charging rectifier designed for high output power applications. It features a new digital rectifier control using thyristor technology, meeting modern power supply requirements.
Specifications: The rectifiers typically use B6C circuit rectifier bridges, with options for fully-controlled 12-pulse rectifier bridges for special applications. They can be adapted with various modifications to suit specific applications. Performance values are customizable, and parallel operation is possible with up to three devices.
Control System: The core of the thyristor control is the AT90 control board, featuring an AVR microcontroller with ISP Flash and CAN Controller. It includes all necessary control and signaling interfaces, as well as an RS-232 interface for external computer connections.
Display and Alarms: The LCD display panel allows easy adjustment of measured values, displaying all operating parameters clearly. Standard messages include general alarms, battery operation, and low battery voltage, with additional signals and monitoring options available.
Applications: THYRIDIN-AT90 rectifiers are suitable for various environments, including high ambient temperatures and conditions with shock and vibration. They are used in substations, power plants, the oil and gas industry, shipping, and rail transport.
Technical Data: Input voltage is 400 V/230 V with a frequency of 50 Hz/60 Hz. The power factor at full load is approximately 0.95 inductive. Output voltage ranges from 6V to 440V, with a static voltage tolerance of ±1% and a ripple max of 5% with a disconnected battery. Current ranges from 6A to 1000A.
DC-UPS Systems: By combining rectifiers with batteries, uninterruptible DC power supplies (UGV systems/DC UPS) can be created. These systems protect DC electric consumers from power failures, using lead acid and nickel-cadmium batteries for energy storage.
Customization and Support: JOVYATLAS offers a variety of options and configurations for the THYRIDIN-AT90 series, with representatives available to provide further information and customized quotes.

Product Range THYRIDIN-AT90 Rectifiers with Thyristor Technology www.jovyatlas.de www.jovyatlas.de www.jovyatlas.de DC-Power Supply within high power ranges Rectifiers with Thyristor Technology Type THYRIDIN-AT90 For higher output power and robust application the charging rectifier type THYRIDIN AT90 is the most widely used series. JOVYATLAS has developed a new digital rectifier control in thyristor technology that meets the current requirements of modern and safe power supply requirements. The recitifiers type THYRIDIN AT90 usually using rectifier bridges in B6C circuits. For special applications fully-controlled rectifiers with 12-pulse rectifier bridges are available, too. The systems can be adapted to the respective application by various optional available modifications. The performance values ​​ variable, depending on customer requireare ments. To increase the power range it‘s possible to connect the rectifiers into the parallel operation (n +1). Parallel operatino is possible up to max. 3 devices. The heart of the thyristor controll is the special controllboard AT90, an AVR microcontroller with ISP Flash and CAN Controller. All control and signaling interfaces being important for the rectifier operation and an RS-232 interface for connection to an external computer, too, are provided with the controllboard. The LCD display panel of THYRIDIN-AT90 - systems allows the easy adjustment of all measured values. All operating parameters are clearly displayed and easy to use. In addition, various alarms and error messages, as well as the battery operation are reported via LED display. The following messages are available as standard: Relay messages: general alarm, battery operation, battery voltage low rectifier on, battery operation, Acoustic signal, fault Optionally a number of additional signals and monitorings via additional LEDs or relay cards can be implemented, e.g. manual switch-over onto emergency mode, manual temperature tracking on panel, compensation of the voltage drop on the load line, automatic loading, parallel operation to increase power up 3 devices, etc.. We gladly will advise you on the various options and possibilities. JOVYATLAS supplies thyristor rectifiers type THYRIDIN-AT90 for different requirements and applications. Whether application under high ambient temperatures or shock and vibration - we will adapt the rectifiers to the specific requirements of our customers.
