24VAC Low Voltage Input Electronic ballasts for fluorescent lamps

24VDC and 12VDC input electronic ballast

12VDC and 24VDC 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.

	Quantity	1-10	11-50	51-100	101+
PST-EB40S24AC		$34.00	$27.50	$24.90	$19.00
PST-EB20D24AC		$34.00	$27.50	$24.90	$19.00

This is a compact, high efficiency, switchmode regulated electronic ballast for use when 24VAC is available. This is useful for low voltage systems, such as security, irrigation, sprinkler installations and HVAC. This is an inverter-style ballast that uses high frequency to eliminate the flicker which is seen in AC powered ballasts.

EB series 24VAC ballasts are designed for fluorescent tubes with heating filaments at both ends. Once the power is applied and the tube will light immediately without flicking. They are not suitable for cold cathode lamp/tube without filaments.
