PWM II 230 1 Basic / 8.5 - 8.5 A single-phase inverter
For single-phase pumps up to 1.5 HP. Single-phase/single-phase.



The WaCS PWM II 230 1-BASIC / 8.5 inverter for electric pumps maintains constant pressure as the flow varies by regulating the pump speed.
It has a flow sensor and a pressure sensor inside that allow it to know the operating conditions of the system instant by instant, ensuring constant pressure as conditions change.
The PWM II 230 1-BASIC / 8.5 inverter combines comfort and savings, integrates all the necessary protections for a pump, and is simple to install and configure. It guarantees maximum silence of the pump and an increase in its average life.
It can drive any type of pump and energy savings can reach up to 60%.
The PWM II 230 1-BASIC / 8.5 uses single-phase power for single-phase pumps up to 1.5 HP delivering a maximum current of 8.5 amps.
Ideal for domestic applications, especially where it is necessary to replace a pressure tank without changing the pump.
The inverter is supplied with input cables with a Schuko plug to connect to the electrical current and output cables with a Schuko socket to connect the pump.
