(1) +5V adjustable +10% (+12 will track). Preset to 5V +2/-0% at 50% rated load.
(2) Total peak wattage must not exceed 60 watts. The +12V peak of 4.5A is for a maximum of
30 seconds. During peak loading, the +12V regulation limits are +4/-7%.
(3) Measured by using a 12 inch twisted pair terminated with a 10mfd capacitor and 0.1mfd ceramic
capacitor in parallel with primary and secondary ground holes connected together.
(4) Cross regulation is +5%.
