VMAX Charge Pump (VCP) devices are
specifically designed to work in parallel with 12V batteries and power sources
to achieve several objectives:
1. Boost and deliver massive current
surges: VCPs can provide a significant surge of current, which is particularly
useful for powering 12V mobile audio systems, hydraulics, and other inductive
loads. These loads often require a high amount of current during peak
operation, and the VCP helps meet these demands.
2. Maximize SPL levels and minimize
vehicle light flickering: By delivering a boost in current, VCPs help maximize
the sound pressure level (SPL) produced by audio systems. Additionally, they
help prevent flickering of vehicle lights that can occur when the power supply
is insufficient to meet the demands of the audio system.
3. Eliminate the need for large
battery banks: Instead of relying on a large number of batteries to supply
power to high-power audio systems, VCPs offer an alternative solution. By
efficiently boosting and delivering current surges, they reduce the reliance on
multiple batteries, saving space and cost.
4. Minimize failures of power
amplifiers and subwoofers: Low voltage drops can cause power amplifiers and
subwoofers to underperform or fail. VCPs help mitigate this issue by ensuring
that the voltage supplied to these components remains at an optimal level,
preventing performance degradation and potential failures.
5. Increase the lifespan of vehicle
batteries: Repeated deep discharges can significantly shorten the lifespan of
vehicle batteries. VCPs play a protective role by preventing the batteries from
experiencing deep discharges, thereby increasing their lifespan.
6. Support motors and inductive loads
during startup: Motors and other inductive loads require a high amount of
current during startup. VCPs assist in providing the necessary surge of current
during these initial moments, ensuring smooth startup and operation of such
