Guangdong EMAX Electrical Co., Ltd. products

This 30kW rack-mounted liquid-cooled load bank is our latest R&D product, specially designed for data center applications. It features a high adjustment precision of 0.1kW and integrates key components including a PLC, pressure sensor, flow meter, and temperature sensor. The system uses DN25 stainless steel water pipes and supports a maximum flow rate of 40LPM, making it suitable for testing a variety of data center equipment such as CDUs (Coolant Distribution Units), PDUs (Power Distribution Units), and more.

This is a customized compact high-power resistive load box, which greatly facilitates transportation. The maximum size of a single side is 2700mm, which can be easily loaded into a 20`GP container. The specially customized high-power fan can easily take away the equipment temperature. The PLC from Siemens brand ensures precise and accurate control of all circuits, and the switch from ABB can effectively prevent circuit failures. All door gaps are waterproof, and the control room can reach IP54 level.

This 100kw load bank is equipped with extra-large air inlets and outlets, designed to efficiently reduce the temperature of the equipment, ensuring quick heat dissipation during operation. This load bank features a compact yet robust structure that optimizes space usage without compromising on performance. The design focuses on both functionality and aesthetics.

The 30kW AC/DC Switchable Load Bank has been designed with attention to both compactness and efficiency, ensuring that it performs well in demanding testing environments. Here’s how these design features contribute to its functionality.

This 600KW RLC load bank consists of three parts: resistance-inductance-capacitance load, protection system and control system, mainly including alloy resistors, AC reactors, AC capacitors, electrical parameter data acquisition system, control system, protection system, heat dissipation system, auxiliary control, spare parts facilities, etc. This load bank is an outdoor version and the control room can meet IP54 level. It adopts Siemens PLC control and can be controlled by third-party laptops, PC.,etc through TCP/IP. 

This load bank is an AC resistive-reactive integrated load box, which can be used for inverter and AC power supply testing. It supports three load modes: pure resistance, pure induction, and resistance-induction. It can be used with an AC contactor test platform to simulate user load usage conditions and test the power supply`s load-carrying capacity, output performance indicators, etc.

A resistive-reactive load bank is a device that simulates real-world loads by combining both resistive and reactive components, typically used for testing power sources like generators, UPS systems, and transformers. The capacity of kVar directly affects the stability of the power grid, the service life of power equipment and the quality of power. Therefore, in the design and operation of the power system, it is necessary to control and compensate reactive power.

RCD load is a nonlinear simulation load that can be used to test UPS power supplies, inverter power supplies, etc. to understand their true working ability when carrying nonlinear loads such as computers and network equipment. By accurately detecting the power output power and quality of the power supply, it can be avoided that it cannot drive the load or pollute the power grid during actual use, thereby ensuring power supply safety. This equipment can meet three test methods: 1. A three-phase AC source (can meet the three-phase four-wire/two-phase three-wire test requirements) 2. A single-phase AC source 3. Three independent single-phase AC sources
