INTRODUCTION
The Magellan Powertronics MCRII Series three phase battery charger / DC power supply
utilises Switch mode or Phase controlled AC to DC conversion technique together with the
latest micro-processor hardware and software to produce advanced charging systems suitable
for Lead Acid or Nickel-Cadmium batteries.
The MCRII charger is a constant voltage type, with current limit and two voltage levels:
float
and
boost
. The boost level is used to recharge the battery whilst the float is used to keep the
battery in a fully charged condition. For applications using Sealed Lead Acid batteries, the
boost function may be disabled.
The boost mode can be initiated manually or automatically. The manual boost is initiated by
depressing the momentary Boost button and the status is indicated on the LCD display. The
charger then remains in the boost for a period of 0 to 24 hours (selectable) after which it will
automatically revert to float mode. The automatic boost is activated if the current into the
battery exceeds a pre-set limit for a pre-set time. The automatic boost is also controlled by a
boost timer (0 to 24H).
