Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang SJE-RHOMBUS dari 3G Electric.

What types of pump control panels does SJE-RHOMBUS offer?

SJE-RHOMBUS manufactures simplex and duplex pump control panels for multi-purpose pumps, grinder pumps, and effluent pumps. Simplex panels control a single pump, while duplex panels manage two pumps for alternating or lead-lag operation. Panels are available in single-phase (120V AC or 230/240V AC) and three-phase (208-240V AC) configurations, with current ratings from 7 A to 31.8 A. Enclosure options include NEMA 3R (outdoor) and NEMA 4X (corrosion-resistant).

What is the difference between demand dose and timed dose dosing schedules in SJE-RHOMBUS panels?

Demand dose dosing activates the pump based on liquid level, typically using a float switch or sensor to trigger operation when the tank reaches a preset high level. Timed dose dosing operates the pump on a fixed schedule, independent of liquid level, which is useful for applications like chemical dosing or controlled discharge. SJE-RHOMBUS panels specify the dosing schedule in their model numbers, allowing selection based on system requirements.

Are SJE-RHOMBUS control panels suitable for outdoor installation?

Yes, many SJE-RHOMBUS panels are rated for outdoor use. Models with NEMA 3R enclosures are designed for outdoor installation, providing protection against rain and sleet. Panels with NEMA 4X enclosures offer additional corrosion resistance for harsh environments, such as wastewater treatment plants or chemical processing areas. Always verify the enclosure rating on the specific model's datasheet.

What accessories does SJE-RHOMBUS provide for float switches?

SJE-RHOMBUS offers cable brackets and mounting assemblies for float switches, including float bracket assemblies made from PVC or polypropylene. These accessories are compatible with universal series float switches and support wire gauges from 16 AWG to 18 AWG. Mounting assemblies are rated for 125V AC or 30V DC and include connectors for easy installation. They are used to secure float switches in tanks or basins.

Can SJE-RHOMBUS grinder pump panels handle reversing operation?

Yes, certain SJE-RHOMBUS grinder pump panels, such as the VSGS-240-3-31.8 model, feature reversing functionality. Reversing panels alternate the motor direction to prevent clogging or to clear blockages in grinder pumps. Non-reversing panels are also available for standard applications. The reversing capability is specified in the product model number and datasheet.

Does 3G Electric supply SJE-RHOMBUS products?

Yes — 3G Electric (S) Pte. Ltd. supplies SJE-RHOMBUS products. We stock the SJE-RHOMBUS catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
