The definitive solution for automatic switching between power sources
HMA is an electronic device for switching between power sources that can be combined with any MultiPower “HMA ready” device.
Automatic power source management
HMA, combined with any MultiPower “HMA ready” device, switches between AC power (mains or generator) and DC power (photovoltaic panels) completely automatically, based on the programmed logic.
Mechanical disconnection of the two power supplies
Two interlocked contactors guarantee the uniqueness of the power supply and ensure separation in order to ensure maximum electrical safety.
Control of auxiliary generator
When the AC power is provided by a generator, HMA is able to start or stop it according to need. HMA also monitors any signs of failure or running out of fuel.
Manual switching
Via the keyboard it is possible to switch from one power supply to another or even interrupt the power supply.
Timed switching
The transition from the photovoltaic power source to the mains supply (or generator) and vice versa takes place at a time set by the user.
Switching from digital input
Switching is controlled by the opening or closing of a digital input.
Switching by flow
Switching from DC to AC power supply takes place automatically to satisfy the desired daily flow. It is also possible to set a time after which transition to AC is allowed.
