SRS electronic ballast - YZ-DFA

SRS electronic ballast

usually,our electronic ballast have three types for each model,economic ballast as our type C,standard ballast as our type B,specialzied ballast as our type A.

the difference of these types as followings:

Type C:Unique design,slinky appearance,portable,compactstucture,safety and relibility,withabnormal protection,PF>0.92, average service life:20000h,with two yeats warranty,east to install.use metallic housing,fire-retardant,explosion-proof,insert type terminals,easy to install.

Type B: Circuits in use have been specially treated: high power factor(PF>0.98), low harmonic wave(THD<20%), low voltage, good tripping performance, electromagnetic compatibility(with EMC) (no pollution of power grid), abnormal protection (abnormal protection function before expiration of the tube’s service life, over volt-age and short circuit protector), low surface temperature rise, small self-consumption, low failure rate,average service life:30,000 hours, with three years warranty,good comfort (no flash, no noise, low radiation, effective improvement of lighting quality and illumination).

Type A: Specialized Electronic ballast using digital circuit,with chip driving,constant output power,active correction,wide voltage, constant output power , high power factor(PF>0.99), low harmonic wave(THD<10%), goodpreheating start,electromagnetic compatibility(no pollution of power grid),abnormal protection function before expiration of the tube’s service life,overvoltage and short circuit protector),low surface temperature rise,small self-consumption,low failure rate,average service life:50000 hours,with five years warranty,,good comfort(no flash,no noise,low radiation,effective improvement of lighting quality and illumination).
