It supports stable constant current and constant power loading, test accuracy up to ±0.2%, which can truly restore the actual working state of switching power supplies, ensuring the authenticity and consistency of UL certification test data.

• Multi-mode Load Simulation, Wide Compatibility
Supports resistive fixed load, constant current and constant power three test modes, covering full test scenarios of AC/DC switching power supplies, power adapters, LED drivers and communication power modules. Multi-level step load adjustment meets UL standard full-load, half-load and variable-load aging test requirements, realizing one machine for multiple purposes.

• Laboratory-grade Safety & Anti-interference
The shell adopts UL-certified fireproof and anti-static material, with standardized insulation wiring and anti-shock protection structure. Built-in EMI anti-interference design, which avoids external signal interference affecting UL test results. Equipped with over-current, over-temperature, short-circuit and overload full protection, meeting laboratory high-standard safety operation specifications.

• Intelligent Data Recording & Report Export
Supports local manual control and PC upper computer intelligent control, automatically recording test time, voltage, current, power, temperature and load parameters in real time. It can generate standardized UL test reports and data curves, facilitating laboratory data filing, certification review and factory quality traceability.

• Compact Structure & Customized Service
Desktop portable and standard rack-mounted( rack mounted ul load bank ) dual structures are optional, occupying small space and convenient for laboratory placement and mobile use. Passed CE and ISO9001 certification, supporting customized power, voltage and special test functions to meet personalized UL test requirements of different power supply products.
