In this series of articles we will discuss the options you can have in your battery charger. You can check out these options for choosing your desired battery charger solution.

Charge Dividers

Our charge divider option adds series diodes to the output of our charger to isolate multiple banks of batteries. The battery banks, in effect, do not see each other, allowing each bank to be charged completely without feeding off each other. Typically, a charge divider is used for marine applications, but they have also been provided for various applications.

Available configurations are: 2 Battery Bank Negative Common, 2 Battery Bank Positive Common, 3 Battery Bank Negative Common and 3 Battery Bank Positive Common. We also offer external charge dividers, built in separate enclosures.

Lightning Arrestor

Not only do Lightning Arrestors protect a charger against lightning, they also provide protection against high voltage surges and spikes. During normal operation, the surge protector is not active; however, when the surge protective device detects a voltage above its design rating it activates by safely diverting the surge or spike away from the charger.

Lightning arrestor are required for those applications requiring additional surge voltage suppression or to meet customer specifications. In recent years, there have been some major revisions to the standard that these devices are required to meet. This has prompted the redesign of the previous lightning arrestors. Due to the way they have evolved, the name has changed to Surge Protective Devices (SPD). The SPD used here meets the current UL 1449 3rd Edition standard, and are classified as SPD Type 1.

Blocking Diode

A blocking diode is wired in series with the chargers output to provide isolation. Today it is typically used in multi charger applications to isolate the chargers from each other should one of the chargers experience a problem. Contrary to popular belief they are not used to prevent the charger from draining the battery during a power failure. The charger output fuse or breaker prevents a charger failed component from discharging the battery. The charger alarm drain during an AC failure represents a very small load on the battery and is not enough to be considered.
