OEM Open Frame Battery Charger

Ideal Power are developing a highly reliable, open-frame battery charger with a universal input that can integrate into any planned or existing charging system as an OEM solution which provides designers and installers the flexibility to achieve the desired charging system without the extra cost and complications of a fully enclosed battery charger.OEM Open Frame or Custom Enclosure
Available as an install-ready, OEM sub-assembly which can be white-labelled with another brand as to appear as a complete solution, the OEM open frame battery charger aims to reduce the design, development and installation of battery charging systems by implementing the following strategy:

Technically Advanced
Using Smart Microprocessor-controlled technology, the charger will encompass a 7-stage function which covers charge, equalisation and maintenance states and uses Power Factor Correction (PFC) to ensure higher efficiency.

The design features protection circuits such as over-current, short circuit protection, over-voltage protection, thermal protection and output-reverse polarity to make it a very safe unit, which is essential when destined for close-quarters applications such as in caravans and motorhomes.

The charger automatically operates in both constant current and constant voltage modes for batteries up to 48V. Although it is best suited to the trusted Lead Acid family of batteries such as Wet Cell (flooded), Gel Cell, and Absorbed Glass Mat (AGM), the charger is also capable of the Lead Crystal chemistry as well. This includes both Starting batteries and Deep Cycle batteries.

7-Stage Intelligent Automatic Charging Process:

  1. Sulphate Prevention Mode (De-sulphate)
  2. Bulk Charge
  3. Absorption Charge
  4. Recondition Mode
  5. Optimisation Mode
  6. Float Charge
  7. Maintenance Mode

Considering the financial cost of replacement batteries, it is a fundamental requirement to extend the battery life as much as possible, a requirement that using this system can achieve by vastly improving the life-cycle and performance of the battery.

In system critical applications such as Uninterruptible Power Supplies (UPS), it is also important to ensure that the battery is able to function correctly when it is needed most which is an attribute that only an intelligent battery charging system can offer.


Attempting to attain the correct approvals for your application is not only difficult, but it is also a large drain on resources. Utilising a charging system that already meets European standards and approvals saves time and prepares a platform of certifications to build upon for other country-specific certifications. The CE marked Ideal Power open-frame battery charger conforms to EN 60335-1 and the battery-charger specific EN 60335-2-29 approval.

Design time

Attempting to design a bespoke charging system is a very time consuming and costly process, one which requires specialist engineering knowledge. An open-frame battery charger provides the ability to progress through the initial design stage straight to the secondary system-design stage. This saves time and resources and ensures the project progresses through to completion quickly.

Maintain and Prosper

Using the intelligent charging system the battery can be recharged by a strategy that best suits the condition of the battery cells. This approach means the battery cells are protected from over-intensive charge rates which damage them. Instead, a sympathetic approach is employed which allows the charging system to automatically switch between charging modes whilst battery condition is constantly monitored and protected from over-charging which means the charger can be left connected at all times to safely and efficiently maintain the battery.

Optimal Applications:

  • Battery Back-up for Critical Systems such as Railway Signalling
  • UPS Systems
  • Access Lifts
  • Caravan Leisure Battery Charging
  • Motorhome Leisure Battery Charging
  • Warehouse Support Systems (Forklifts etc)
  • Compatible Electric Vehicles (Golf-Carts etc)
