DF/FF 系列 3-4kW 工业 X 射线发生器 | Spellman 高压电源

斯派曼DF/FF 系列X 射线发生器采用新的逆变器设计，这包含了将IGBT 用于电源开关，并提供了可靠的新等级。此外DF/FF 内置灯丝电源的重新设计，通过在更高频率下运行，从而消除了在正常运行等级下的音频噪声。DF/FF 运用一个正弦波电流源，通过相移串联谐振电路在开关频率大于20kHz 来产生高压直流。这种技术消除了通常与开关和电源控制调节有关系的不良的电磁辐射。此系列电源的高效率，允许在5 1/4” (3U) 高的机箱内进行空气冷却。

典型应用:

X 射线衍射(XRD)
X 射线荧光(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.

OPTIONS

RS232 - RS232 Interface
220FSI - 220Vac Fail Safe Interlock
208-3P - 208Vac Three Phase Input

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.
