2000W High Voltage Power Supplies

Высоковольтные источники питания серии SLS обеспечивают мощность до 2000 Вт при выходном напряжении в диапазоне от 160 до 360 кВ. В этих источниках используются резонансные инверторы с патентованными органами управления, обеспечивающими высокую надежность в жестких условиях эксплуатации. Блок высоковольтного умножителя имеет гибридную конструкцию, в которой сочетается надежная герметизация и наличие воздуха, что снижает общий размер устройства. Умножитель, состоящий из плотно прилегающих пластин с напряжением 20 кВ, позволяет гибко формировать блоки питания для различных конфигураций выходных параметров.

Типовые применения:

• Ионная имплантация
• Ускорители частиц
• Электронные пушки

Corona Dome Terminations:

The SLS Series of “stack” configured high voltage power supplies come in a various output voltages and different physical configurations. Appropriate corona relief is required for these units to operate at maximum output voltage. Frequently users will provide the corona relief needed so Spellman will provide stack assemblies that by themselves will not be able to operate at maximum output voltage corona free. Please be certain to discuss your requirements with Spellman to be assured you get a stack assembly in the physical configuration you require for your application. The optional K941 Toroid (5˝ x 20˝) should be considered if customer corona relief will not be provided.

Electronic Component (Power Source)

SLS series is intended for installation as a component of a system. It is designed to meet CE standards, with conditions of acceptance often being: customer provided enclosure mounting, EMC filtering, and appropriate protection, and isolation devices. The SLS series is not intended to be operated by end users as a stand-alone device. The SLS series power supply can only be fully assessed when installed within a system, and as a component part within that system.

eSL Option

The eSL Option provides a vacuum fluorescent front panel display and Ethernet connectivity. Both the 1U (1.75”) and 2U (3.5”) SL product offerings are available with the eSL Option. Using the front panel local controls the main menu has the following features:

Local/Remote Control

Allows operation from either the local front panel or remotely via the Ethernet Category 5 connector.

Features Menu

Allows control over Adjustable Overload Trip and Slow Start features.

Tutorial Menu

Provides information on how to use the local front panel interface.

Diagnostics Menu

Provides information on the revisions of the hardware, firmware and IP address. Additionally the Diagnostics Menu provides information on the status of the internal low voltage housekeeping power supply voltages.

eSL Option power supplies can still be fully controlled via the SL’s comprehensive remote analog interface, so these units are fully backwards compatible with standard SL power supplies.
