Product Introduction
The SILV-1000L is a 1000kW resistive AC load bank manufactured by Rata, designed specifically for testing power systems such as generators, UPS, and switching equipment.
The device has a rated test voltage of 380Vac, supports 50/60Hz frequencies, and uses a three-phase four-wire star connection. Its core advantage lies in its precise 1kW load step resolution. Through a combination of multi-stage load switches (1kW to 200kW), it can achieve accurate load regulation from 1kW to 1000kW, meeting stringent testing requirements.

FAQ
1
What are the advantages of the SILV-1000L compared to the previous 1000KW resistive load bank?
(1) The SILV-1000L has been upgraded in size, only half the size of the original.
(2) The cooling airflow has been shortened, allowing four of 600mm diameter fans to dissipate heat, resulting in a 20-30% increase in cooling efficiency.
(2) The cooling airflow has been shortened, allowing four of 600mm diameter fans to dissipate heat, resulting in a 20-30% increase in cooling efficiency.
2
What standardizations are used in the control loop?
The control loop adopts the Siemens Si-board design standard. Main control components such as relays, fan motor protectors, and touchscreens use Siemens components, improving reliability.
3
Is 1kW accuracy truly meaningful in actual data center testing?
Absolutely. Data center expansion is typically done gradually, rack by rack, rather than at full capacity all at once.
1kW step allowance:
(1) Accurately simulates single-cabinet or single-row load operation;
(2) Verifies the UPS efficiency curve within the 20%–80% load range;
(3) Finely evaluates generator low-load operation stability;

4
Is this equipment suitable if the data center requires 8–12 hours of full-load testing?
Yes. This equipment is designed for continuous operation, employs a forced air-cooled structure, has an airflow of approximately 70m³/h per kW, and supports operation in environments from -20°C to +50°C.
Suitable for: Long-term full-load stability testing; backup power endurance testing; annual emergency drills.

Suitable for: Long-term full-load stability testing; backup power endurance testing; annual emergency drills.
The equipment uses a three-pole AC contactor for graded control, a copper busbar structure in the main circuit, and a graded load switching method. It also features: automatic over-temperature unloading; automatic unloading due to insufficient airflow; emergency shutdown; ensuring equipment safety during switching tests.
6
How does the load cell support system coordinate with phased construction in a modular data center?
Modular data centers are typically deployed in phases.
The load bank's multi-level load combination design allows for: simulating 30% load in the first phase; 60% load in the second phase; and finally 100% load. It adapts to different phase testing needs without requiring equipment replacement.
7
Data centers increasingly emphasize "digital test records." Does the load cell support data archiving?
Yes. The Nexus-1 PC control system enables: real-time voltage, current, power, and frequency display; automatic data acquisition; curve generation; test record saving; meeting data center acceptance and audit requirements.
8
Is it reliable in temporary outdoor testing environments?
The control cabin is IP54; it features industrial-grade axial flow fans; stainless steel louvered air inlets; and a wide environmental temperature range suitable for: outdoor testing; containerized data centers; and temporary commissioning during construction.
9
If the data center expands to over 1MW in the future, is it scalable?
It can be tested by connecting multiple load cells in parallel. The load bank adopts a standard copper busbar structure and industrial contactor control, facilitating multi-unit combination and meeting higher capacity verification requirements.
10
Compared to ordinary load banks, what are the differences of this device in data center applications?
1kW fine resolution (suitable for precise testing); supports remote software control; suitable for long-term continuous operation; multiple fan and temperature protection mechanisms; compact structure, facilitating server room layout; more compliant with data center testing specifications, rather than just for simple generator load testing.
11
What type of data center project is this device best suited for?
New data center acceptance testing; UPS system upgrade testing; diesel generator commissioning; annual emergency power drills; modular data center expansion testing.
