Open-type IPX3 / IPX4 / IPX4K Test Setup

Unlike enclosed box-type IPX3/4 test device having an enclosed chamber, the open-type configuration offers a simplified design. The system consists of two primary support columns, the oscillating tube, and a central turntable assembly. This “enclosure-free” architecture is particularly advantageous for testing oversized products or for laboratories requiring an unconstrained test area.

To ensure safety and reliability, the system features a specialized dual-column design that isolates water from electrical components:

• Fluid Management Column: One column houses an integrated water reservoir for immediate supply. It is equipped with a standard inlet for connection to an external water source, ensuring a continuous flow for long-duration testing.
• Electrical Control Column: The opposing column contains the motor, circuitry, and core control systems. This isolated design ensures the total separation of water and electricity, maximizing operator safety and equipment longevity.

The system is managed via an ergonomic control panel located on the column exterior. Users can choose between a high-definition PLC touchscreen or a traditional tactile button controller. The interface allows for:

• Pre-Set Test Ratings: Quick selection of IPX3, IPX4, or IPX4K parameters.
• Customizable Timers: Set and monitor precise test durations.
• Flow Monitoring: An integrated, high-precision flow meter allows for manual or automated adjustment to meet the exact flow rates specified by relevant international standards (such as IEC 60529).

The two support columns are bridged by a high-grade stainless steel oscillating tube (15 mm diameter). This hollow, semicircular component is precision-engineered to provide uniform water distribution. To accommodate a wide range of specimen dimensions, we offer eight interchangeable radii: R200, R400, R600, R800, R1000, R1200, R1400, and R1600 mm.

Easy Maintenance: Each water outlet is equipped with a detachable, syringe-style needle tip. These are threaded for quick manual assembly, allowing for rapid replacement if a nozzle becomes clogged.

Standard Compliance: The system includes interchangeable needles with 0.4 mm inner diameters for standard IPX3/4 testing and 0.8 mm diameters for high-flow IPX4K testing.

Flexible Configuration: For IPX3 testing, high-quality metal plugs are provided to selectively block nozzles, ensuring the spray pattern meets the required 60° vertical limit.

Controlled by a high-torque drive system, the tube swivels with extreme precision:

IPX3 Rating: Swings ±60° from the vertical.

IPX4/4K Rating: Swings ±175° (near-total rotation) from the vertical.

Standardized Speed: The system maintains a constant angular velocity of 1 second per 60°, ensuring repeatable and accurate test results.

The turntable assembly is designed for stability and functionality, consisting of a reinforced base, adjustable support rod, and the rotating platform.

Rotational Control: An internal motor provides smooth, bi-directional rotation at a standard speed of 5 RPM (customizable upon request).

High Loading Capacity: The standard turntable supports up to 50 kg, with reinforced custom solutions available for heavier specimens.

Test Under Load (TUL): A built-in waterproof power socket is located at the base of the turntable. This allows samples to be energized during the test, with power integration options that can be synchronized with the main equipment or operated independently.

Mobility: Both the turntable base and the support columns are fitted with heavy-duty industrial casters, allowing the entire setup to be easily repositioned within your waterproof testing facility.
