Test resistance load device [Device for testing standalone operation prevention function]

Test resistance load device [Device for testing standalone operation prevention function]

Load capacity of approximately 20kW! Supports three-phase unbalanced loads! Various settings can be changed according to test conditions, including three-phase and single-phase configurations.

The test resistance load device is designed to be used as a load for adjusting the power flow balance during the standalone operation prevention function test of power conditioners in solar power generation systems, or to prevent reverse power flow. The maximum load capacity is 21.8 kW, which can support up to five units in parallel operation for a typical household power conditioner (equivalent to 4 kW). 【Features】 - It is possible to switch between three-phase and single-phase according to the test voltage. - The load capacity increments are fine, with a minimum of 10 W (in single-phase), allowing for precise power flow balance adjustments. - In tests using three-phase power, the load for each phase can be set individually, enabling the creation of load imbalance conditions. - As a safety mechanism to prevent resistor burnout, two systems are installed: one that prevents the load from being activated unless the cooling fan is operational, and another that forcibly cuts off the power supply if the resistor temperature exceeds a certain level. - Switches are available in two patterns: wired and wireless. - The wired switch is connected with a 10 m cable, which can be extended up to 20 m with an extension cable. - The wireless switch is limited to the range of the wireless LAN communication, but distance extension is possible through the use of a relay.

[Case Study] Commissioning of a Hyperscale Data Center in Japan

[Case Study] Commissioning of a Hyperscale Data Center in Japan

A case that enabled the operation of a hyperscale data center within a specified period and budget.

We would like to introduce a case study that made it possible to conduct performance testing of various scenarios in a hyperscale data center for global enterprises at the Collocation Data Center. In the company's facility, thorough testing and commissioning were essential to ensure that various infrastructures of the data center, such as power and cooling systems, were functioning without issues and to confirm the complete operational capability and fault tolerance of the data center. Aggreko conducted a site survey and determined that a combination of 200kW load devices, LV cables, and connectors was optimal for the customer's data hall. A total of 32 load devices, amounting to 4.8MW, were prepared to simulate the thermal load on the data center's power, cooling, and infrastructure. As a result, it was guaranteed that the system would operate appropriately under various scenarios and meet the stringent industry standards and regulations regarding uptime and energy efficiency. [Case Summary] ■ 200kW Load Devices: 32x ■ LV Cable Length: 11.2km ■ Data Hall Capacity: 4.8MW *For more details, please download the PDF or feel free to contact us.
