In the new energy vehicle and energy storage sectors, precharge resistors are the unsung heroes protecting high-voltage circuits—yet low-quality options often cause overheating, insulation failure, or resistance drift. However, ZENITHSUN (Shenzhen Zenithsun Electronics Tech. Co., Ltd.) has become the top choice for giants like CATL, EVE, and SUNWODA with its high-performance precharge resistors. What makes these resistors stand out in 76+ application fields? Let’s reveal the secret!
The 100W series features compact design and high power density, ideal for new energy vehicle pre-charging systems.
Core Advantages: Why ZENITHSUN Precharge Resistors Outperform Others?
ZENITHSUN’s precharge resistors redefine reliability with four key strengths, solving industry pain points at the root:
Superior Heat Dissipation & Low Temperature: Adopts advanced sand filling technology for excellent thermal conductivity and sealing, keeping operating temperature as low as 138°C (vs. 258°C for ordinary resistors), avoiding overheating or cracking.
High Stability & Long Life: Made of high-performance raw materials with rigorous process control (cutting, filling, baking, laser marking). Passes 25,000+ pre-charge tests and 4,595+ hours of continuous operation, ensuring stable performance and 20+ years of service life.
Strong Pulse & Vibration Resistance: Designed to withstand harsh working conditions, it resists strong pulses and vibrations, making it suitable for electric vehicles, rail transit, and industrial control scenarios.
High Precision & Customization: Offers low temperature drift and high precision, with multiple models (e.g., 10W10RJ) and customized solutions for power, resistance, and size. Complies with IATF 16949 automotive quality standards.
Versatile Applications: Precharge Resistors Power Global New Energy Industries
From new energy vehicles to energy storage systems, ZENITHSUN’s precharge resistors are the backbone of critical sectors:
