electronic choke with microprocessor control Lumatek digital ballasts offer the most advanced technology on the market for greenhouse lighting. Compact and completely silent , and have the highest efficiency - more lumens per watt than any other model . The microprocessor technology allows adjustment to the model lamp and its condition , as well as the mains voltage. 1000 - watt model has four modes of operation : 600W, 750W, 1000W and 1000W SuperLumen. For lamp 1000W 1000W to start and then you can switch to 1000SL (+10%) or decrease of 750W or 600W. Lamp from 750W to 750W start and then you can switch to 600W. Lamp of 600W engage 600W. Important: do not turn the throttle mode SL (super lumen) when using metal halide (MH) bulb. Measurements show up to 30% more brightness than analog throttles and 10-15 % more than competing electronic . The electronic throttle is a solution to the problem of irregular power supply voltage ! Analog chokes age with time start rustling and consume more power , more heat at the expense of decreasing luminosity . For electronic ballasts this is not happening , they maintain the same level of emission and efficiency. Lumatek throttles are programmed for " soft start " , that is to start the lamp is not needed peak voltage and current , which prolongs the life of the bulb , not the electrical and loaded to safely launch a large number of reactors simultaneously. To ensure safe operation, the choke Lumatek is programmed to be turned off in case of short circuit, burning bulb or lack thereof . Completely silent , packed into a sealed box . Each reactor has been tested for 12 hours to provide maximum reliability . Technical data: Voltage: 220 -240V 50/60Hz Current : 4.50A Input Power : 1060W Output Power : 1000W Efficiency: > 0.99 THD ( harmonic distortion ): <10% Imax: Isr . < 1.7 Outside tamperatura : from -25 ° C to 50 ° C Heating (Δt): 30 ° C protection class :> IP23 Lumatek is designed to work with quality lamps. Turn the power off when replacing the lamp. Lumatek recommended that the lamp be changed 6-12 months. Very important is the lamp to cool completely (20-30 minutes) before turning again! Conversely shortens her life also should not be off before the lamp has reached full capacity . Keep the throttle from overheating and humidity! Mount of at least 15cm apart.
