HMA is an electronic device for switching between power sources that can be combined with any MultiPower “HMA ready” device.
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.
Two interlocked contactors guarantee the uniqueness of the power supply and ensure separation in order to ensure maximum electrical safety.
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.
Via the keyboard it is possible to switch from one power supply to another or even interrupt the power supply.
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 is controlled by the opening or closing of a digital input.
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.
If irradiation falls below a predetermined value or the power generated by the panels is not sufficient to operate the pump, HMA starts up the generator, if present, and switches to AC supply.
When irradiation returns above the minimum threshold, the generator is switched off and the pump is restarted with DC power.
