Modular Battery Chargers REVOLUTION Series Fast, Opportunity & Conventional
Innovative. Efficient. Unmatched Energy Savings.
The REVOLUTION Series is an innovative line of high frequency battery chargers incorporating cutting edge modular power design to deliver peak efficiency greater than 93% and efficiencies greater than 90% throughout the entire charge cycle. As the charge cycle progresses and the output current tapers down, the charger will turn off unneeded modules, allowing the remaining modules to operate at peak efficiency.
- Input Voltage: 480VAC, 3-phase ± 10%
Total charge cycle efficiency > 90%
Peak charging efficiency > 93%
- User Interface: LCD/Keypad, Ethernet (optional)
- Cooling: Forced air (fans)
- Certifications: UL and cUL listed; CEC Compliant
Conventional charging entails that the battery is charged over an 8-10 hour period, rests for another eight hours, and is used over an eight-hour shift. As such, conventional charging is ideal for one-shift applications where no battery changing is required.
Conventional charging doesn’t charge the battery at the same rate over the full eight hours. It will charge the battery faster over the first four to five hours, and then turn the amperage down and run another few hours to level off the battery. Multi-shift operations will need two or three batteries per truck respectively, so that batteries can be used in a lift truck while other batteries are charging and cooling down.
Opportunity charging is a good choice for extended shift operations where battery changing can be eliminated. Opportunity charging extends the run time of aging batteries and recoups the lost capacity that comes with age.
Opportunity charging frees up warehouse space and personnel as it often eliminates the need for dedicated battery rooms, spare battery storage, battery-handling and battery-changing equipment. It also cuts down on time spent traveling from worksites to battery rooms, significantly increasing productivity and decreasing the risk of injuries suffered while hoisting heavy batteries in and out of trucks.
Fast charging charges the battery at rates three to four times that of conventional chargers, and at every opportunity possible. This includes breaks within and in-between shifts, and can eliminate the need for additional batteries.
Fast chargers work quickly because they don’t turn down the rate of current the way a conventional charger does. These chargers keep the charge rate high during the whole charge time. Gassing is increased due to the higher constant charge rate and increased temperatures. An equalize charge once a week will help balance the sulfating that occurs during charge cycles.
Variable Configuration Architecture
The REVOLUTION series of chargers are modular concept chargers offering multiple configuration capability. The independent power modules, installed in parallel, allow the user to add additional modules, increasing the charger’s output for a minimal upgrade cost.
The parallel module design provides built-in redundancy that ensures that in the event of a module failure the charger will continue to operate until the problematic module is replaced. The charger display will indicate the module failure, and with the removal of a few screws the faulted module can simply be unplugged and a new module plugged in. Diagnosis and repair of a REVOLUTION is the simplest and fastest of any charger in service today.
