DSL Indicating lamps are used in factories where DSL busbars
are installed to know when 3 Phase power is applied to the crane.
DSL Indicating Lamp take 3 phase power as input and emit three colours in the visible spectrum- Red,Yellow and Blue.
They act like a status indicator for the presence or absence of the 3 phase input power.
The intensity of the light reduces or increases with the change in 3 phase input voltage.
In the situation where , 1 phase is not available or phase failure, the light for that particular phase will switch off .
During malfunctioning of crane or maintenance operations of crane, the DSL indicating lamp will indicate to everyone on the factory floor whether the power is present or absent.
Anand Systems engineering DSL indicating Lamp can be easily installed by anyone with the help of 4 screws. Anand Systems engineering DSL indicating Lamp is constructed with extremely high quality and long lasting Light emitting Diodes. These LEDs do not require a heat sink .
Installation of 3 Phase DSL Indicating Lamp:
3 phase voltage display unit can be easily installed by anyone with the help of 4 screws. It is constructed with extremely high quality long lasting LEDs and powder coated metal body.
When Correct Three phase voltage is applied , all three indicating lamps light up and get illuminated.
When one of the three phase voltages is not present,only two indicating lamps light up.
Individual Indicating Lamp
Each Individual Lamp of the DSL Indicating Lamp is made up of 3 Parts.
Transparent Polycarbonate Cover.
Electronic Circuit with Leds
Bottom ABS plastic Circuit Base
Individual PCB with LED
