The 500-1K-QTH is a fixed DC stabilized switching power supply that produces 1000W for use with 1kW QTH light sources such as the Sciencetech TH3 housing. It is an external power supply that accepts 120VAC and 240VAC inputs, for use with 120VDC 1000W QTH lamps.

There are two input voltage options for this power supply, please specify 115-120VAC or 220-230VAC when ordering.

QTH Lamp Compatibility
This power supply produces 120VDC output whether the input is 120VAC or 220VAC. Hence, the power supply is designed for use with a 120V 1000W QTH lamp. Please note that Sciencetech carries both 120V and 230V 1000W QTH Lamps. Regardless of the input voltage, only the 120VDC 1000 QTH Lamp can be used.
