Aplications:
-For power supply ultraviolet lamps ( Gállium or Mercury
or Metal Halide ) used in furniture industry, silk-screan, flexographic
and others.
Main Advantages:
-Balanced current in input three phases and remains stabilized
in the UV lamp, even during the mains voltage variation;
-Lamp current adjustment from 40% to 100% of the nominal value,
in a linear form, performed by three-phase eletronics circuits;
-Alternating the selection switch in the Wattage Control Module
( MCP ), the same transformer works with Gállium or Mercury
lamp;
- Automatic memorization of the last lamp current adjustment before
to turn off machine.
Items Furnished with Transformer:
-Digital Hour Counter - measures lamp worked hours;
-Electronic Potentiometer for adjust lamp current;
-Digital Ammeeter and digital panel LCD 2x16’;
-Three-minutes timer to disconect ventilation when lamp turns
off;
-Ventilation and lamp command circuit.
Messages in LCD:
-Lamp off; overtemperature; defect in frequency inverter; AC input
abnormal/overload; emergency.
Technical Specifications:
-Input Voltage: 220 or380V depending of alterations in the transformer
and MCP (others voltages under consult);
-Frequency: 50 or 60 Hz.;
-Lamp Wattage: 6/9/10/13,5/15/18/20 KVA ( others Wattage under
consult );
-Efficiency: approximately 90%;
-Power factor: near of unitary (it is not necessary to add capacitors
in the input mains).
Protections:
-Overtemperature sensor in the transformer, actuates during cooling
system fail, changing the lamp current to half wattage;
-Lamp overload sensor, actuates when the lamp current surpass
the maximum specified, turning off the transformer;
-Emergency circuit, actuate when mat stop, changing the lamp to
half wattage;
-Phase lacking sensor and inverted sequence, actuates during lack
one phase or sequence of inverted phase in the input mains, blocking
the lamp functioning. |
