Rigorous Testing for Reliable Pump Controllers

Unmanned Pump Control, Choose 3S

Top-Tier Quality

Core components utilize top-tier branded parts. With an optimized layout, specialized processing, and integrated electrical safety measures, the system offers robust waterproofing and high-temperature resistance, ensuring long-term, stable, and reliable operation of the pump control system.

ST Chip - Top 3 Globally
The ST industrial-grade MCU excels in signal acquisition, data processing, and logic control, ensuring faster and more precise controller response.
HongFa Relay - Top 3 Globally
As a key actuator in the controller, the HONGFA relay ensures reliable switching, precise pump start/stop, solid electrical isolation, and robust safety protection.
CHINT MCB - Top 1 in China
As a fundamental protection component, CHINT MCB rapidly cuts off power during overloads or short circuits, delivering reliable circuit isolation and safety protection to prevent motor overheating and equipment damage.
CHINT AC Contactor - Top 1 in China
The CHINT AC contactor enables remote motor start/stop, handles high inrush currents with stability, and works with relays and MCBs to provide layered protection for safe, reliable system operation.
SMPS Module - Wide Range Voltage Design
Using a Switched-mode Power Supply module instead of a transformer with a wide input voltage range of AC 90–460V effectively prevents PCB damage.
PCB Protection Process
The PCB uses a three-proof process plus a self-developed nano coating, providing strong protection against humidity, salt mist and corrosive environments.

Rigorous Tests

At 3S, we believe that exceptional quality comes from uncompromising attention to detail. Every pump controller must pass 13 rigorous tests before leaving the factory, including safety tests, environmental durability tests, mechanical strength tests, and EMC tests. These ensure stable, reliable, and long-lasting performance in all application environments.

650°C Glow-wire Test
Simulates extreme overheating situations, verifying the excellent flame-retardant capability of the smart pump panel's shell material to ensure it does not become a source of fire.

AC Hipot Test
Ensures the controller can withstand high voltage without insulation breakdown.

SPD Thermal Stability Test
Focuses on verifying the thermal stability of the lightning protection module under abnormal overload conditions, fundamentally preventing fire risks caused by the module's own overheating.

70°C / 95%RH Temperature and Humidity Cycle Test
In alternating high temperature and high humidity, tests the controller's ability to resist moisture intrusion and long-term aging.

Dust and Sand Test
In simulated dusty environments, ensures the 3S pump panel is tightly sealed, effectively preventing dust from entering the interior and protecting precision components.

55°C High-temperature Burn-in Test
Allows the smart pump control starter to operate at full load under high temperature, simulating long-term harsh working conditions, screening out potential defects, and improving overall product lifespan and reliability.

Salt Spray Test
Subjects the product to a high-concentration salt spray environment, simulating coastal or corrosive industrial climates, to verify the corrosion resistance of the machine's enclosure and internal components.

Vibration Resistance Test
Simulates continuous vibration during transportation and operation, ensuring the smart pump control starter's internal components are securely welded and connected, and will not loosen due to vibration.

Drop Test
Simulates accidental drops that may occur during installation or use, verifying the impact resistance of the 3S intelligent pump panel's shell and internal structure, ensuring it "can withstand falls and is reliable."

±4kV Electrostatic Discharge Test
Verifies the controller’s immunity to±4kV electrostatic discharge, ensuring it operates reliably without crashes, restarts, or damage under ESD events.

4kV Lightning Surge Test
Simulates lightning strikes transmitted through the power grid, verifying the 3S outdoor smart pump panel's ability to withstand instantaneous overvoltage.

2kV Electrical Fast Transient Burst Test
Resists sudden electrical noise interference from surrounding equipment, ensuring the controller's operational logic remains undisturbed.

8/20μs, 5kA Simulated Lightning Strike Test
Withstands extreme high-current shocks simulating direct lightning strikes, providing the highest level of safety protection for the equipment in extreme weather.
