INTRODUCTION
The LPC 40 is a low profile, completely automatic, modified 3-step, single channel battery charger
designed for vehicles with a single battery system. The LPC 40 improves upon package size and
parasitic systems. The charger is also ruggedized to withstand the shock and vibration encountered by
vehicle mounted equipment.
FEATURES
I. LPC 40 BATTERY CHARGER
• 1-hour “boost” voltage to compensate for cable voltage drop
• Automatic current limiting
• Remote Battery charge/condition indicator display
• LED status indicators
• AUX output with AC or DC mode rocker switch and automatic fuse protection
• Reverse polarity protected
• Dual AC input fuse protection
II. CHARGE CONTROLS & ELECTRONIC REMOTE SENSING
The LPC 40 contains a precision voltage controller to maintain the battery’s charge. The output
terminal is voltage regulated and internal circuitry provides for boost voltage during loaded situations.
Output voltage regulation and boost voltage compensate for cable voltage drop. Using high-frequency
switching technology the output terminal voltage is compared to a reference voltage, any error
detected is then used to control the charger output at the desired level. There is no “trickle charge”
and therefore no danger of overcharging and water boil-off.
III. AUTOMATIC CURRENT LIMITING
When batteries are severely discharged, some battery chargers can be overloaded due to the high
charging current required. The LPC 40 contains an automatic current limit. The current limit feature
limits the output current to 40 amperes when charging a deeply discharged battery, or if the starter
cranks the engine while charging. The current limiter thus eliminates the need for an ignition interlock
circuit.
IV. BATTERY SELECTOR SWITCH (LEAD-ACID/AGM OR GEL-CELL)
Used to select between Lead-Acid/AGM or Gell-Cell batteries
