12VDC and 24VDC Input Electronic ballasts for fluorescent lamps

24VAC input electronic ballast for fluorescent lights

These high efficiency ballasts are for 20 and 40 watt fluorescent light fixtures in cars, RVs, boats, and solar systems.

Applications also include display lighting in ice cream trucks, ambulances, buses, commercial vans, and subways.

This is a compact, high efficiency, switchmode regulated electronic ballast for use when DC supply voltage is available. This is useful for RVs, boats, solar power installations, green light fishing, and wherever 12VDC or 24VDC is available for lighting. This is an inverter-style ballast that uses high frequency to eliminate the flicker which is seen in AC powered ballasts.

EB series DC/DC ballasts are designed for traditional fluorescent tube with heating filaments at both ends, but the filaments are not necessary, so the tube will light even if the filaments are burned out. Once the power is applied and the tube will light immediately without flicking. They are not suitable for cold cathode lamp/tube without filaments.
