ii. Output frequency of the led ice bucket must be 50Hz ± 2%.
iii. led ice bucket efficiency when operating with resistive loads at full load must be at least 85%.
iv. The quiescent current drawn by the led ice bucket must not exceed 2% of the rated current of the led ice bucket.
v. The output waveform’s Total Harmonic Distortion (THD) must be less than 5% at full load.
vi. The led ice bucket must not produce noise more than 60db at 2m.
vii. led ice bucket or led ice bucket circuits must include
a. i) Low battery shut down must be at battery voltage not less than 10.5 V for tubular plate battery in case of 12 V systems. For 24 V or 48V systems low battery shut down voltage must be 10.5 x N V. Here N stands for the number of 12 V batteries in a series connection.
