BATTERY CHARGERS

Computronic Controls are world leaders in the design of battery chargers for standby engine and industrial DC power applications. Computronic chargers include advanced features that optimise the performance, reliability and lifetime of your batteries:
- multi-stage charge regimes: rapid charge recovery, followed by constant voltage float charging
- thyristor, switch-mode and hi-impedance transformer designs
- low ripple (<1%), necessary for charging sealed/recombination cells
- alarm outputs, for remote signalling of fault conditions
- temperature compensation of output float voltage
- 12V or 24V nominal output voltages
- 3 to 30+ Amp output ratings
- 'autoboost' feature, prevents overcharging
- open-frame, protective cover and stainless steel, wall-mounted enclosure variants
- CE, UL, CSA, FM and NFPA approvals
Standard chargers for standby engine applications include:
 |
