Tungsten Lamp Deuterium Lamp Power Supply For Spectrophotometer

Detailed Product Description
|
Product Description Introduction OWPS-0216DT series Deuterium lamp power supply was developed by OWO
team in 2014,and its perfect replacement for expensive original
models, the product has CE proved and 18 months warranty. OWO now
offer Deuterium lamp power supply that is commonly used in UV
spectra chromatography , atomic absorption, UV-Visible
spectrophotometer ,other spectroscopic equipments and also can be
connect with tungsten lamp. Compared to the traditional linear
power supplies this deuterium lamp switching power supply abolishes
cumbersome transformers, it has set filament preheat, high voltage
trigger and constant current control are just a number of features
the deuterium power supply to ensure the stability of UV spectra. A
small compact size, light weight and one of the biggest advantage
is applicable to international mains input Voltage in the 85-265V
AC, no switching required! The power supply also has control port
allowing external control signals (such as CPU ormanual) which can
easily turn on or off the deuterium lamp. OWPS-0216DT series
deuterium power supply has professional anti-electromagnetic
interference design, theelectromagnetic interference reach to grade
A. OWPS-0216DT series power supply support deuterium lamp and
tungsten lamp use, the voltage offering for the tungsten lamp can
be customized to 6V,12V,24V, power range:5W-30W. Direction for use The control port has an optocoupler insulated with the power supply
as the circuit above. control mode: High level :turn off, Low
level: light turn on. High level voltage range DC 3 ~ 12V,current:
above 1mA. Signal port is a feedback signal of the lamp light on or
off, the signal can be used to CPU Light up the lamp(Deuterium lamp)Input AC 85 ~ 265V, The control port: low level, the relay closed
,the filament preheating, the preheating time is fixed, can't be
adjust. the lamp will light up in constant current working status
after 10 seconds. The trigger voltage is automatically applied to
the anode after preheating. High stable deuterium lamp ultraviolet
energy will be produced after 1 hour, Constant flow accuracy can
reach to 0.005‰. Please do not watch the flare in the tube after
the lamp light up, or your eyes will be damaged by the light! If
you need to temporarily turn off the lamp, please add a 1mA current
High level voltage DC 3-12V to the Control port ,the turn off
signal must be kept at least for 3 seconds to make sure the circuit
reset! the lamp will start to preheating and working after the Turn
off signal disconnect. if your instrument controlled by CPU, and
the lamp light up once the CPU turn on, as the CPU's reset output
High-level voltage then return to Low-level, so the lamp will be
short -time cut off during this period (less than 3 seconds),and
the internal circuit can't be reset, the lamp will not light up
even the Turn off signal has disconnected. The right solution for
this situation is input the High-level (Turn off Signal ) for 3-5
seconds, then transfer to Low-level (Turn on signal),then the lamp
will be light up. Lamp signal port application(Figure 4): 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 Light up the lamp(Tungsten lamp)The control port voltage range: DC 3-12V,current:10mA.
High-level:turn off The DC output can be fine adjustment by
potentiometer on the PCB, used to adjust the tungsten lamp energy.
6V tungsten lamp: the adjustment range:5.0-5.7 V,max current:2.0A.
12V tungsten lamp: the adjustment range:10.5-11.5V max
current:2.0A. Please do not set the voltage over the range, it will
make the lamp not work stable. Size Information |
