The Auto Charge SD 150 is a state of the art, high output battery charger that provides a rapid recharge for an emergency vehicle’s battery. A special equalizing circuit raises the charger’s output voltage for 1 hour when the charger is turned on. This reduces the time required to charge the battery and helps rejuvenate the battery’s plates. At the conclusion of the equalize period the output switches to the normal float charge mode. The patented "sample and hold" circuit precisely measures the battery voltage eliminating errors due to voltage drop in charging wires.
A series of diagnostics continually checks the operation of the charger. LED’s indicate normal and abnormal operation. Excessive output voltage is detected, as are insufficient output, high temperature and high resistance connections. An LED also indicates when the battery is disconnected. The remote indicator is a dual bar graph indicating both charger voltage and output current.
