AC POWER CONSUMPTION 1/8 power, ohms (AC Current and Heating, 120Vac)
(1) 1/8 power represents typical operating conditions.
(3) Full power is breaker limited to short periods.
(2) 1/3 power represents peak program levels.
(4) For 230V, multiply AC current by 0.5. For 100V, multiply AC current by 1.25.
