3-step Battery Chargers for Cyclic Applications
The 9840, 9740 and 2045 series is part of a family of 3-Step chargers from 10 – 240 watts. These 3-step chargers are designed for Cyclic applications, where the need to re-charge a battery as quickly as possible is the main requirement.
The charger operates in a boost/timer mode for approximately 4 ½ hours. At the end of the timer period, the charger will return to a Float Voltage level, where it can be left on indefinitely. The timer is automatically activated when the AC power is switched on.
