Product Description

It can be widely used in centrifugal pumps, submersible pumps, multi-stage pumps, deep well pumps, sewage pumps, booster pumps, pipeline pumps, etc.

Main Technical Parameters

Rated working voltage: AC380V±10%/50Hz

Matching motor power: 0.75kw-18.5kw

Host static power consumption: <3kw

Three levels of water level display, in order: low, middle, high

Maximum control distance: no strong electric field, magnetic field and interference environment ≤ 2000 meters

Timing rotation time: adjustment range 0-480 minutes

Anti-rust inspection time: adjustment range 0-30 days

Over/under voltage protection range: 304v-456v (≤3 seconds trip) upper and lower limits are adjustable

Automatic fault conversion: 1 second

Over/under current action time: 0.1 second-3 minutes (inverse time limit characteristic)

Phase loss action time: <2 seconds

Main Function

Control mode: One use and one backup, double pump rotation, automatic fault conversion, high-position double pumps at the same time

Control features: automatic control, one use and one backup or dual pumps to start at the same time

Transmission characteristics: float, pressure gauge, pressure switch, electrode probe

Fault status: fault cause display, fault sound and light alarm

Independent key setting of over-current/under-current parameters (adjustable for no-load delay start)

After the over/under voltage is protected, it will automatically start after the voltage returns to normal

Water supply of upper pool, water supply of lower pool, pipeline constant pressure control

Digital voltage display, current display, three-level display of upper/lower pool water level

Over current protection, under current protection, phase loss protection, over/under voltage protection, short circuit protection

Automatic/manual one-key switch

Automatically start the water pump after a power failure

No-load restart: adjustment range 0-999 minutes
