It enhances system integration flexibility, accelerates secondary development, and helps controller ODMs / integrators efficiently meet customers’ customized needs.

Panel dimensions:

186×66×121 mm, with a compact design that makes the 2 Pump Intelligent Control Box adaptable to electrical control cabinets of various specifications.

Installation method: 

Open-hole mounting, equipped with standard screw fasteners for quick and stable installation.

Terminal types: Adopting universal pluggable terminals for convenient and reliable wire pressing; equipped with industrial-grade FPC connectors with wear-resistant plated contacts, capable of withstanding multiple insertions and ensuring long-term stable connections.

Interface integration design: Digital and analog signals are centralized on the same signal board, facilitating wiring and system expansion.

Digital Input: 6 sets of terminals, supporting connections of float switches, liquid level switches, relay contacts, proximity switches, buttons, knobs, and solenoid valve signals.

Analog Input: 2 sets of terminals, compatible with 4-20 mA pressure transmitters, liquid level sensors, and 0-5 V remote pressure gauges.

Communication interfaces: The 3 phase versatile pump controller supports RS485 (Modbus RTU), Ethernet, 4G, 3G, and WiFi for remote control.

Power Adaptability：

Power input range: The 2 Pump Intelligent Control Box supports wide voltage AC110–415V (AC440–490V optional), compatible with single-phase and three-phase electricity. By selecting the phase type via system parameter P001, the same panel can adapt to multiple power supply schemes, helping assemblers reduce inventory and compatibility costs.

Software Function Flexibility：

Configurable functions: A parameterized setting interface allows quick setup of key parameters without programming. The screen menu directly sets "start/stop pressure,""switching delay,""motor current protection value,""duty/standby pump rotation time," etc.

Ease of Debugging and Maintenance：

Plug-and-play: The 3 phase versatile pump controller comes with a built-in universal pump control program. After assemblers complete wiring, only settings of U01–U04 are required for operation:

U01: Selection of water supply/drainage signal devices

U02: Rated voltage setting (110–490 V)

U03 / U04: Rated current setting for pumps A/B, supporting automatic recording via self-learning function

Diagnostic function: The LCD screen features clear fault diagnosis and display (clearly showing 17 fault names such as overflow, sensor failure, locked rotor, dry running, etc.), significantly reducing after-sales difficulties for assemblers.

Modular options: It supports multiple configurations to meet different application needs:

Standard intelligent version

RS485 physical remote version

Short-range WiFi App control version

Global IoT remote version

The 3S-32-PA 3 phase versatile pump controller covers various application scenarios (such as booster, drainage, circulation) with fast delivery, reducing inventory pressure of various components.

Water supply liquid levels: Dry running alarm level, low level (dual-pump operation), medium level (single-pump operation), high level (pump stop). Connecting different numbers of signal devices enables various functions (e.g., dry running alarm, signal loss, single/dual-pump operation).

Drainage liquid levels: Low level (pump stop), medium level (single-pump operation), high level (dual-pump operation), overflow alarm level. Connecting different numbers of signal devices enables various functions (e.g., signal loss, single/dual-pump operation, overflow alarm).

Single Pump Operation：

Single Pump Operation: Only one pump runs, and the other remains stopped.

Application scenario: Systems without mandatory standby redundancy (e.g., small domestic water supply).

Simple operation, low energy consumption, but reliability depends on a single pump.

Simultaneous Dual-Pump Start：

Simultaneous Dual-Pump Start: Both pumps run synchronously, doubling system flow instantly.

Application scenario: Fire pumps, occasions with sudden peak water supply.

The 2 Pump Intelligent Control Box ensures rapid response to high-demand moments, avoiding insufficient water pressure.

One Duty/One Standby：

One Duty/One Standby: One pump runs long-term, and the other monitors and stands by.

Application scenario: Mostly used when the owner or project party designates a main pump.

The 2 Pump Intelligent Control Box flexibly adapts to different engineering configuration requirements.

Alternating Duty：

Alternating Duty: The two pumps automatically switch in turn based on time or frequency.

Application scenario: Community secondary water supply, HVAC systems.

Balances wear, extends pump unit lifespan, and reduces maintenance frequency.

Timed Rotation Alternation：

Timed Rotation Alternation: Forces pump switching at set intervals even without faults or load changes.

Application scenario: 24-hour continuous operation occasions such as data centers and industrial cooling systems.

The 3 phase versatile pump controller ensures balanced operation time of the two pumps, avoiding faults caused by long-term operation.

Standalone Timer Control：

Standalone Timer Control: Automatically controls dual-pump start/stop according to set time, no sensors required.

Application scenario: Small residences, light industrial water supply, or simple farmland irrigation projects.

Easy installation, low cost, reliable execution of timed start/stop, facilitating quick deployment.

Parallel Alternation with Load Sharing：

Parallel Alternation with Load Sharing: Dynamically determines single-pump/dual-pump operation based on system needs.

Application scenario: Municipal water supply, high-rise buildings, industrial systems with variable loads.

Energy-efficient by supplying on demand, ensuring stable water supply.

The 3S-32-PA dual-pump control panel offers an ideal solution for controller assemblers with its high compatibility, flexible configuration, and modular design. Whether it's a booster pump set, a water supply pump set, or a fire pump set, this 2 Pump Intelligent Control Box can quickly adapt to different signal types and power supply schemes, helping assemblers improve overall system efficiency, reduce after-sales maintenance difficulties, and meet customer customization needs.
