A96

The LaMarche A96 provides highly reliable, hot swappable 130 VDC power with full load sharing capability in a compact, modular rectifier system.

At a height of only 4RU in a four across 23″ rack configuration it offers high power density combined with high efficiency. There is no need to shut down the system to change a rectifier. With current limiting circuitry, voltage regulation, high efficiency and high power factor, the A96 is the ultimate modular rectifier for Utility applications.

The A96 is more than a rectifier/battery charger, it is also a power supply/battery eliminator. The loss of one rectifier will not affect the operation of the remaining rectifiers. Complete front panel accessibility and a plug-and-go design ensure quick, convenient installation without the possibility of wiring errors.

Installing a unit only takes a minute. Adverse power conditions do not affect the A96 DC output. Its AC input line regulation operates over a range of 185-264 volts, with a frequency range of 45-66Hz.ge can hold up to 4(four) 20 Amp rectifiers which will provide a total of 80 Amps of power.

A36D

The LaMarche 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 separate adjustable voltages for floating or equalizing lead or nickel-cadmium cells. An equalize switch is located on the front panel of the charger for manual activation or a multi-mode electronic timer can be used for automatic activation. 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.
