The A36D Controlled Ferroresonant Rectifier/Power Supply is often used for industrial control or Utility power applications. This Charger has many inherent advantages such as voltage regulation, high efficiency, high power factor and short circuit protection.
Steady state output voltage remains within +/- 1/2% of the setting from no load to full load and for AC input voltages within +/- 10% of the nominal input voltage. The Model A36D is internally filtered to be no greater than 32dBrn (“C” message weighting) and 30 millivolts RMS for all conditions on input voltage and output load with or without batteries connected. This allows the A36D to be used as a battery eliminator.
