MADE IN U.S.A.
Controlled Ferroresonant Rectifier / Power SupplyThe La Marche Model A36D Controlled Ferroresonant Rectifier / Power Supply has many inherent advantages such as voltage regulation, high efficiency, high power factor and short circuit protection. These chargers provide adjustable voltage levels for floating or equalizing lead or nickel-cadmium cells, which can be done digitally with the LCD/ VFD display options. The equalize cycle is activated either manually through a switch on the front panel, or automatically scheduled (adjustable through the menu).Steady state output voltage remains within ±0.5% 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.
Standard Features• Digital Metering• Load Sharing / Paralleling• Current Walk In• Equalize Timer - adjustable from 1-144 hours with
five selectable modes of operation (manual, automatic every 7, 14 or 30 days and equalize after sensing a low DC voltage)
• LED Status Indicators:Float & Equalize Voltage, AC “ON”, Low DC Current,Low & High DC Voltage, Blown DC Protection, Summary
• AC Input Breaker• One Pole DC Output Breaker / Single Phase Units• Output Fusing / Three Phase Units• AC Power Failure Alarm, One form “C” Contact• 2 Form “C” Contacts for each of the following:

All A36D units are filtered to 32 dBrn “C” with or without batteries connected.Load SharingIdentical La Marche A36D units, when connected in parallel, are capable of sharing the DC load within ±5% for individual unit outputs greater than 5% of the rated output. Two sets of form “C” contacts are provided to indicate when connected rectifiers are capable of loadsharing.Temperature Compensation5 step curve with an average slope of -0.001v/ cell/C°Consult factory for other compensation rates.Remote EqualizeWhen Remote Equalize feature is enabled, switching one A36D charger into Equalize mode would switch all other parallel A36D chargers, in the system, into Equalize mode.

Current Walk InOutput current will gradually increase after the charger is turned on eliminating surges and overshoot.AC BreakerA two pole breaker, on single phase units opens both legs of the AC service to 208 and 240. Breaker opens phase side of 120 VAC service. A three pole breaker is supplied on three phase units.
DC Breaker / DC FuseA single pole output breaker is supplied as standard on single phase units. A DC Fuse is standard on three phase units.Alarm Relay ContactForm “C” Alarm Contacts for:
• AC Power Failure• High Voltage Shutdown• High DC Voltage• Low DC Voltage• Low Current• Summary Alarm

1) AC Current Draws based @ 100% load and standard battery cells of 6L (12V), 12L (24V) and 24L (48V). Maximum Current Draw is 115% of ratings shown.2) Must specify only one battery type and number of cells from range shown above. Please consult factory for other available cell ranges if desired range not shown.3) 50Hz units are not UL listed. Please consult factory as enclosure size may change.4) BTU’s are based on 6L (12V), 12L (24V) and 24L (48V). Heat loss is stated for nominal float voltage, 100% output current and nominal AC line.
