Professional Deuterium Lamp Power Supply / Liquid Chromatography Power Supply

Liquid chromatograph power supply

Specifications:

Description:

Compared with traditional linear power supply, GTK series power supply eliminates heavy and inefficient power frequency transformers, and USES high frequency to work, collecting filament preheating, high voltage triggering and constant current control. Has small volume, light weight, high efficiency, etc. Its biggest advantage is applicable to the international civil power, in AC85V - 265 - v any voltages can be within the scope of normal light work, and ensure the stability of the ultraviolet spectrum. The power supply is also equipped with an isolated control port, and the external control signal (such as CPU or manual) can be easily switched on and deuterium lamp. The GTK deuterium lamp switch power supply adopts the specialized design, its electromagnetic conduction interference reaches the a-level, and reduces the interference effect on the instrument circuit.

There are two types of GTK series deuterium lamp switch power supply. The gtk-02162.5 is suitable for the deuterium lamp with the filament voltage of 2.5v, and the gtk-031510 is suitable for the deuterium lamp with the filament voltage of 10V. Their appearance is the same, please note that the power model and the deuterium lamp model match.

Applications:

Liquid chromatograph, gas chromatograph, atomic absorption, visible analytical instrument, etc.

There is also a deuterium lamp state detection port, which can be used to detect whether the deuterium lamp is lit.

AC input: L,N,PE, (PE be must be grounded)

Lamp: filament-filament-Anode

Control: ±

Signal: ±

The wire of the lamp must be well connected with the power supply !

The wire of the lamp must be well connected with the power supply !

Lamp signal port application: choose the external resistor according to the DC voltage(DC3-12V),internal pull-up resistor is 10K,(If signal isolation is required,can use an optocoupler instead of the external resistor).

Signal type: lamp turn on:Low-level ,lamp turn off: High-level

Installation and Cooling

The power supply can be vertical and horizontal installed, do not drill other holes on the housing, the power supply needed cooling fan under the ambient temperature above 35℃.
