DF/FF シリーズ 3-4kW 産業用 X線発生器 | スペルマン高電圧電源

　3kW/4kW X線発生器は電力スイッチ用IGBTを備えた最新イ ンバータ設計で、最新レベルの信頼性を提供します。再設計され たDF/FFの内部フィラメント電源は、より高い周波数での動作 によって、通常使用時でも低周波ノイズを除去します。DF/FF はサイン波電流源を使用しています。そのサイン波電流は 20kHz以上のスイッチング周波数で位相シフトする直列共振回 路により発生します。

この技術は、スイッチングや電力制御レギュレータにより通常 発生する好ましくない電磁波を除去します。高効率なので、51/4 インチ（3U）高シャーシでも空気冷却が可能となっています。

用途

• X線回析（XRD）
• 蛍光X線（XRF）

ADDITIONAL FEATURES

Water Flow Switch:

A 24Vdc signal is available on the rear panel to turn on the cooling water to the X-ray tube. This signal can be enabled either when control power is on or when the high voltage is turned on. (Customer must specify).

Fail Safe Interlock:

A 24Vdc signal is available on the rear panel to energize an external X-ray on lamp. This signal is energized when the high voltage is turned on. High voltage will not enable if this circuit is open. (A 220Vac signal is optional).

Preheat and Ramp:

Automatic preheat and ramp control circuits are provided which ramp the kV and mA slowly to set levels. kV ramps in approximately 10 seconds while mA ramps in approximately 20 seconds.

Output Connector:

75kV, 3 conductor Federal Standard X-ray connector. -60kV is connected to terminal “C”. Terminals “S” and “L” are jumped together. The filament output is connected between terminals “C” and “S”. Other configurations are optional. (On the FF3, all output connections S, L, & C are connected together).

Remote Signal Connector:

Remote interface is available via a 50 pin mini D connector. Extensive remote programming and monitoring is provided.

Electronic Component (Power Source)

DF/FF 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 DF/FF series is not intended to be operated by end users as a stand-alone device. The DF/FF series power supply can only be fully assessed when installed within a system, and as a component part within that system.
