Protection: IP55
The motor is powered by a single-phase frequency converter (Varipulse). We recommend a 10A, D-type miniature circuit breaker for protection.
Operation:
- Stops the pump motor at each stroke between 0-20% power
- Continuously varies motor speed between 20-100%
Display: LCD
Power supply: 230 V AC, 50/60 Hz
Protection: IP55
Control signal (3 ways)
1., manual operation
2., automatic operation, based on an analog signal (0-10 mV or 4-20 mA),
3., automatic, proportional operation, based on an external pulse signal (e.g. water meter), the motor controller calculates the divisor/multiplier values ​​based on the specified pump type and water meter data
Selectable water flow: 1.5/2.5/3.5/5/10/15/25/40/60 and 100 m3/h
Water meter pulse signal: 0.25/0.5/1/ and 10 liters/pulse
Current input impedance: 500 Ohm
Voltage input impedance: 100 kOhm
Error message:
