Engineering manufactures two basic types of DC inverter ballasts ... Instant Start (IS) and Rapid Start (RS). Both types utilize a high efficiency, two (2) IQsistor, push-pull switching inverter to change the low voltage DC source into high voltage, sinusoidal AC power (20-30khz) to start and operate the fluorescent lamp. The standard instant start is inherently more efficient since the ballast output voltage is sufficient to start the lamp instantly and the lamp cathodes are not continuously supplied with power to keep them heated. The optional rapid start version is available for better starting of the lamps when ambient temperatures are less than 50°F (10°C).

Low Pressure Sodium Ballast:

Power Source
The DC power source can be either a battery or power supply. If a power supply is used, it should be capable of delivering twice the input current rating of the model selected for proper starting. Any ripple in the DC power source will be introduced into the lamp output so if lamp flicker is a concern, the DC power input should be ripple-free. IQ-BALs® are also available for AC input applications in a wide range of voltages and operating frequencies.
 
Heat Sink
A heat sink is required for some IQ-BAL® models. Generally, a fixture large enough to hold the lamps provides adequate heat dissipation. However, any piece of metal capable of absorbing heat generated by the ballast can be used. Inadequate heat sinking can result in IQ-BAL® failure. Please consult the factory with specific questions regarding the use of heat sinks in your application.

 

Radio Frequency Interference IQ-BALs® are designed to meet regulations set forth by the Federal Communications Commission (FCC). However, this does not mean that the combination of the ballast, lamp, power source and wiring will meet FCC regulations. Caution should be used to prevent associated wiring from conducting and/or radiating energy. When the battery or power supply is remote from the ballast, a shielded supply line is recommended. Self-shielding is accomplished when the battery wiring and fixture are contained within a metal framework.   Model Selection   IQ-BALs® are categorized by series. Consider the following factors when selecting a model:      Input Voltage Ballasts for AC or DC input are available. The voltages can vary over a range of -10% to +20% of nominal voltage. Models for input voltages not shown on the Series Selection Chart are available as custom models.   Inverter Ballast Lamp Loads Series A One 4 - 8 W T5 lamp Series B One 13 - 55 W lamp; Two 13 - 20 W lamps Series C One 75 - 165 W VHO lamp; Two 60 - 85 W VHO lamps operating from 48VDC Series E One 4 - 55 W or One 18 - 35 W LPS lamp or One 5 - 39 W twin-tube lamp; Two 4 - 20 W or 5 -18 W twin-tube lamp Series J One 60 - 215 W VHO or One 45 -110 W HO lamp Two 60 - 135 W VHO or 45 - 85 W HO lamps Series K One 4 - 40 W lamp; Two 4 - 20 W lamps Series P Two 110 - 160 W VHO lamps Series S One 16 - 32 W lamp Starting Circuit Two types of starting circuits are available. RAPID START (R) provides heater voltages to aid lamp starting and is used with preheat and rapid start lamps. This circuit is recommended for applications requiring frequent lamp starting. INSTANT START (F) produces a high voltage potential to start the lamp and may be used with preheat, rapid start and instant start lamps. This circuit is recommended for applications requiring infrequent lamp starting.    Lamps Operated Models are available to operate preheat, rapid start and instant start fluorescent lamps from 4 through 215 watts. To choose the correct IQ-BAL® Series for your application, see the Series Selection Chart.   Customer Service If the lamp type for your application is not listed on the Series Selection Chart, IQ-BALs® can be customized for specific applications such as: Germicidal High Output Very High Output Ultraviolet Low-Pressure Sodium Other AC or DC Input Voltages In some cases, it is possible to arrange UL Listing for IQ-BALs®. Engineering fees for customization vary according to design needs.   Warranty Models are warranted for one year against defective material and workmanship. Replacement will be made when the IQ-BAL® is returned, IQsportation prepaid, with prior permission, and in the judgment of The Bodine Company has not been subject to misuse, improper installation or misapplication.

Fluorescent standard inverter ballasts operate preheat compact, rapid start, and instant start lamps. The rapid start and instant start lamps are operated in the instant start mode. Instant start is inherently more efficient since the ballast output voltage is sufficient to start the lamp, and the lamp cathodes are not continuously supplied with power to keep them heated. Rapid start ballasts are offered on some models as an option for better starting of the lamps when ambient temperatures are less than 50°F (10°C) or when the lamps are cycled on and off continuously. The ballast topology utilizes an efficient two (2) IQsistor, push-pull inverter to change the low voltage DC source into high voltage, sinusoidal AC power (20–30kHz) to start and operate the fluorescent lamp.
