The company has made its mark as a Manufacturer & Supplier of 120 Degree Central AC Control Panel. The 120 Degree Central AC Control Panel has an electronic overload built with integrated operational amplifier for over current circuit as per site requirement. The electronic latch circuit of the 120 Degree Central AC Control Panel comes with tripping indication for each tripping and there are provisions of reset facilities. The 120 Degree Central AC Control Panel does not hold phase seq. corrector until overload and other parameters are not removed. Complete protection of panel and connected distribution load is ensured. Electronic integrated control card features the output and gives correct phase i.e. RYB irrespective whether input is RYB, YRB or BRY, and it can provide multiple inputs that may be two, three or six sources of power supply.

Details

• Single phase protection both on LT/HT side
• Three phase low voltage cutoff at 350 volts (adj.)
• Three phase high voltage cutoff at 460 volts (adj.)
• Unbalanced voltage tripping 400 (+/-) 10% volts within 1 to 3 sec
• 1 amp sensitivity relay set unit consisting of auxiliary CT primary current as per HP of motor.

The company has come up as a highly reliable Manufacturer and Supplier of DG Set Control Panel. The Automatic Main Failure DG Set Control Panel is known for highly efficient and effective in power supply restoration. The complete automation backs up the mains failure, and that makes the DG Set Control Panel worth investing in.
 
Safety Information :

• Mains failure is described as :
  
  • Direct failure of mains
  • One or more phase of mains being unavailable
  • Phase voltage of mains being out of preset limits (Provisions to set higher and lower phase voltage limits as per site requirement)

• Within range mains supply shall be considered healthy so that continuous running of engine alternator set is avoided
• Load shift to engine supply after suitable time delay, if the engine has started in the event of mains/phase failure or low/high voltage
• Switch load back to mains supply and stop the engine when the healthy supply is restored
• Up to three attempts for starting engine after failure of earlier attempts after suitable time intervals
• Two level fuel sensors for fuel at 50% & 25% respectively

Settable Features :

• Mains failure time – to initiate automatic EA start after 0 to 300 seconds of mains failure
• Mains restore time – to initiate automatic stop of EA after 0 to 300 seconds of mains in stable conditions
• Low oil pressure delay time – 0 to 99 seconds delay of the low pressure oil input alarm from engine start
• Stop solenoid time – 10 to 99 seconds enabling time for "stop solenoid"
• Cranking up time – 0 to 99 seconds enabling time for starter (timer is reset if the engine starts before the programmed time)
• Start attempts – 1 to 3 numbers of automatic attempts during automatic start cycle
• Attempts interval – 1 to 99 seconds time interval between starting pulse attempts
• Cooling down time – 0 to 300 seconds engine cooling time before stopping (engine runs without load)
• Generator voltage time – time of stable generator voltage to close EA contactor to load (0 to 300 seconds)
• Multifunctional meter to indicate Voltage, Current, PF, Frequency & kWh of DG Set
• Safety control trip – Low lubricating oil pressure, high cylinder / water temperature, lack of fuel, alternator fault and over speed

• LLOP
• DG on
• DG battery low
• DG fuel low
• Under speed/over speed
• Stop fault
