This 3-phase brushless DC water pump driver from Shenzhen Tecote Technology is rated at 250 W with an AC input range of 170 V to 276 V. It employs sinusoidal field-oriented control and operates without a Hall sensor, relying instead on back-EMF sensing or observer-based estimation for rotor position. Speed regulation is available through infrared, PWM, VSP, SPI or similar interfaces, and the unit provides speed feedback to the host controller.
The PCB assembly measures 115 mm by 95 mm, a compact footprint suited to integration inside pump motor housings or tight electrical enclosures. Brushless DC pump drivers in this power class typically switch at frequencies between 15 kHz and 20 kHz to maintain smooth torque and minimise audible noise from the motor. Protection logic covers overtemperature, no-load, overcurrent, overvoltage, undervoltage, phase loss, anti-reverse and anti-lock conditions, which are standard safeguards for submerged or remotely installed pump systems.
Target buyers include manufacturers of solar irrigation systems, hot-water circulation pumps, automotive thermal management and small appliance water pumps. The driver suits applications where energy efficiency and variable speed are needed without the maintenance of brushed motors. Importers should confirm with Shenzhen Tecote whether the firmware allows custom speed curves and whether the communication protocol is openly documented for integration with their own controllers.

Shenzhen Tecote Technology Company Limited is located at No. 305, 3rd Floor, A Building, ICC Park, No. 163 Huawang Road, Dalang Street, Longhua District, Shenzhen 518109, Guangdong, China. The address places it within Shenzhen's Longhua manufacturing belt, an area dense in electronics assembly and component sourcing. Its trust tier is listed as harbor, with a response rate of 0.00 percent and zero average response hours, indicating no recent buyer interaction data is available on the platform.
The supplier specialises in 3-phase brushless DC water pump drivers, with this 250 W model representing its focus on small to medium pump motor control. The listing provides detailed electrical and functional specifications but does not mention ISO certification, factory audit status, annual output, number of employees, or established client references. Buyers should request these credentials directly to assess production reliability and after-sales support capability.

Before ordering, confirm that the 170 V to 276 V input range aligns with your local mains or solar inverter output, and that the 250 W rating matches your pump's hydraulic power requirement at the target flow and head. Verify with Shenzhen Tecote that the driver is pre-configured for your motor's back-EMF constant and winding resistance, because sensorless FOC tuning varies with motor parameters. Request a sample for bench testing with your actual pump and controller before committing to volume production.
Shipments from Shenzhen typically depart via Yantian or Shekou port. Ask the supplier for the confirmed lead time in weeks, the Incoterm, and whether export carton or anti-static packaging is standard. For payment, many Shenzhen electronics suppliers accept 30 percent deposit and 70 percent before shipment for new buyers, but terms are negotiable based on order volume and relationship history. Clarify whether the quoted price includes the driver PCB only or also the wiring harness and connector set.
On arrival, inspect the PCB for solder joint quality, component orientation and conformal coating completeness. Run a no-load test at reduced voltage to verify the speed feedback signal and protection thresholds. Measure the actual input current at your operating speed point and compare it against the supplier's specification sheet. Ask for a factory calibration report and whether Tecote supports on-site or third-party inspection by agencies such as Intertek or TUV before final payment and shipment.
