Primax P600 series delivers modular and cost-effective solutions for your DC backup systems. Packaged as a single module unit or within a complex system, the P600 meets your application’s demands. The broad range of controls and options fits virtually any DC backup specification while offering better efficiency and communication.

Why use P600 high frequency switchmode design:

Operation flexibility:

Energy deregulations brought new challenges: Tighter budget allocation is pushing all to do more with less. Using the P600; linemen for example can be assigned to service or fix a charger whenever they are in an area. Management’s need to allocate a service technician is minor therefore, emergency calls are lessened.

Redundancy/N+1 and scalability:

Having more than 1 charging unit in a system opens a wider opportunity to manage emergencies: this natural redundancy can improve reliability and availability of your dc systems. The need of adding more units for future expansion can be achieved with greater ease.

Hot swap:

Ease of maintenance: servicing and repairing SCR and legacy chargers require advanced knowledge and experience in troubleshooting and service. Training resources are limited for senior technologists and engineers to get newcomers entering the power market up-to-speed. The P600 series is considered to be known as a “plug and play” system. Modules are interchangeable, hot-swappable, very easy to install, maintain and service.

Small footprint and high power density:

New regulations such as NERC and aging electrical infrastructure are imposing new stress on space and time management. Extra equipment needs to be installed in substations to support higher demand. Space begins to be tighter over time: the small footprint of the P600 resolves this issue. Up to 200A at 125Vdc can fit in a 19in. 5U expansion sub rack.

Extend battery life:

The very low current and ripple content at much higher frequency than what the battery is sensitive to, the P600 helps in extending battery life by lowering the battery temperature rise due to these effects. Therefore, this will help the battery to gain extra lifespan with improved system reliability.

Clean power:

Thanks to the P600 unity factor and very low THDi to limit electrical pollution reflected on the grid. Our P600’s high efficiency aids in preserving energy and reject unnecessary heat.

Easy to upgrade and refurbish:

The P600 is perfect to replace outdated chargers while keeping the existing enclosure and installation infrastructure.

Better sensitive load protection:

Tighter voltage regulation protects your sensitive load from failing over time due to the dynamic dc voltage swing.


The P600 is compatible with the legacy batteries such as Lead acid and Ni-Cd as well as the Li-Ion new designs. This is attributed to it’s CAN bus communication capabilities to communicate with connected batteries while adjusting its operational parameters to preserve battery life and safety.
