Is PLUS red?   Not always

What color is the plus pole?   In the regular color-coding standard, the PLUS pole is marked by RED color and the MINUS by the BLUE color.

However, in Asia, sometimes there is a reversed color coding, where PLUS is marked by the black color and MINUS by the red color.

Keep this in mind when working in DC installations of equipment from Asia, that in some cases the MINUS may be marked by the red color.

Overview of the DC contactors and switches

The physical disconnection together with the proper fusing is one of the basic principles of the proper construction of the DC circuits. 

Even though there are customers that buy the cells from GWL, very often there is no mechanical disconnection of the battery form the connected electronics. The customers buy the LFP cells, but they do not buy any relays or switches. So, at GWL, we wonder about the safety of such solutions.

The basic hint and advice from GWL are:  Make 100% sure you have a working mechanical disconnection of your battery pack powerlines.

The Communication for BC-16 Battery Meter

The BC16 Battery Meter comes with the TTL communication port that allows reading the data of the BC in a digital way.

Industrial Type Circuit Breakers

Safety is the most important factor of any DC powered installation. To help you with the instant safety, GWL supplies the quality circuit-breakers that can be used for your installation.  The 125Amp DC Breaker is designed to protect the main DC line while the 32Amp and 2AMp models are designed for the auxiliary power lines or for the powering of the accessories and measuring circuits.

DC Disconnect Switches – a Must!

Any DC powered solution should have the ability for instantaneous protection and disconnection. GWL Team keeps reminding the customers of the need to apply proper fusing and also the quick-to-go disconnection switches.

The DC disconnection switches are ideal to make the safety disconnection for your DC voltage solution.

Modular REMA Connectors – Forklift Batteries

The product range for DC applications has been enlarged by the REMA type DC connectors for fork-lift applications.

DC connectors - Make your connection easy!

GWL now offers the Anderson Style connectors for 50A, 175A and 350A ratings.

Make your connection easy and make sure your battery solution has a flexible connection and disconnection. It is always important to be able to disconnect the battery (or the other DC source) components in an easy way.
