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.

Reverse Polarity Protection and LED

This circuit protects against someone accidently reversing the battery terminal connections on the charger (i.e. connecting the battery positive to the charger negative or vice versa). The circuit consists of a diode and a fuse connected in series between the positive and negative output of the charger. If the battery connection is reversed, the diode conducts and the current opens the fuse thus protecting the DC system. The LED provides a visual indication that the polarity has been reversed.

DNP3.0 and ModBus Communication

Communication Options DNP3, MODBUS, IEC 61850 - manufacturers are able to provide communication options to allow chargers to be monitored over a serial connection. These battery chargers can be equipped with serial RS-485, RS-232 or TCP/IP ports for data communication over DNP3.0, ModBus, IEC 61850 and LAN. These different protocols cover the most popular protocols that customers are currently using with their SCADA systems.

The chargers output voltage, current and alarms can be monitored and the float/equalize selection can be selected.

Heat Shrinkable Wire Markers

Some customers require the individual wiring inside the equipment to be identified or numbered on each end with wire markers. Some manufacturers uses the heat shrinkable type, which fit snuggly around the wire ends and are permanent. The electrical schematic is marked accordingly. This greatly helps someone in the field to quickly and easily identify components and wiring for troubleshooting purposes.

2.17. SIS Wiring and Wire Markers

Many specifications call for SIS wire. It is also known as switchboard wire. Typically it consists of a stranded copper conductor that is usually tin coated with cross-linked polyethylene (XLP) insulation. The insulation can withstand temperature extremes and meets VM-1 flame rating. The majority of SIS is gray so wire markers are required in order to properly identify and wire the units. Also, SIS wire is only provided on wire 16 AWG and larger. This is because SIS wire has a thicker insulation jacket and will not fit properly in the insulation displacement connections used in some of the wiring assemblies.
