Technical Parameters
| Model | SN551-125L500A |
| Max. load current | 500A |
| DC response time | ≤5μs |
| Built-in resistor | 9±1mΩ |
| Inner chamber size | W500*500H*D500mm |
| Control method | PLC and Touch screen |
| Inner chamber material | Stainless steel |
| Sealing strip | Corrosion-resistant silicone. |
| Temperature control | Normal temperature RT+10℃~100℃ (can be preset) Temperature rise rate 3℃/min Temperature dial 0.5℃ Temperature uniformity: ±2℃ |
| Test stop condition | 1) The battery temperature drops to 20% lower than the peak; 2) Short circuit time |
| Battery surface temperature | Can monitor temperature changes during battery surface testing |
| Sample rack | Stainless steel SUS #201 perforated steel plate storage rack, with a maximum load-bearing capacity of 30KG on a single layer. The height is adjustable at the same time. |  |
| Hall element collects current signal | Hall elements are used to collect the current generated when the short-circuit system is short-circuited, avoiding the generation of contact resistance, and the data transmission is stable and accurate; |  |
| Lead hole | There is a lead hole with a diameter of 50mm on the left side of the box for test wires to pass through. | 
|
| Chamber door | High-strength hinges are used to fix the door, and at least 2 sets of explosion-proof locks can be installed on the door to fix it. |  |
| Explosion-proof pressure relief device | It has the function of exhaust, explosion-proof and pressure relief. The rear of the protective box has a magnet-adsorbed pressure relief door (200*200mm). When strong airflow impacts, the pressure relief door automatically opens and closes to reduce the impact of the explosion. | 
|
| Lighting | The test chamber door is designed with high-brightness LED lighting to make it easy to see the test conditions in the test chamber. |  |
