TBS Omnicharge Battery Charger

The TBS Omnicharge 12 and 24 volt battery chargers are fully programmable, dual output switch mode battery chargers designed for professional applications.

Combining the latest technologies and the best available parts with years of power electronics design expertise, the Omnicharge battery chargers will deliver long life performance even in the most demanding applications.

A unique active rectifier output stage ensures unmatched efficiency figures. Combined with active PFC, the Omnicharge battery chargers are very energy efficient. This will reduce running costs and guarantees a maximum charge current per AC Watt. All Omnicharge battery chargers are equipped with advanced 4 stage charging algorithms and temperature compensation. Users are also allowed to create a custom charging algorithm for their specific battery, with the TBS “Dashboard” software. The standard available TBSLink port enables remote control and readout via the optional TBS Universal Remote Panel. All Omnicharge units are easy to install and come standard with temperature sensor and a very clear installation and operating instruction.

Note: Specifications subject to change without notice.

1 Maximum output current tolerance is ± 3%. Maximum set-point voltage deviations are ± 0.1V for 12 V and ± 0.2V for 24V models. All set-point voltages are temperature compensated when battery temperature sensor is connected.

2 Value is programmable.

3 Always consult battery manufacturer’s specifications for maximum allowable charge current.

4 At higher ambient temperatures (>40°C), maximum output current may be reduced automatically.

Enerdrive now have the ability to custom program both the TBS Omni charger and ePRO Combi units to suit your battery requirements, if they differ from the standard pre-set voltages. We have also been able to custom program for Lithium batteries. Enerdrive is happy to offer this as a free service to our customers and just needs to be mentioned at time of ordering or discuss with us prior to the job to work out your best option. Ask us for a demo on what can be configured in the TBS Charger & ePRO Combi Products.
