Product info
The SJ-D-1KVA/P11 centralized emergency lighting power supply integrates a high-speed microprocessor and programmable logic devices with sixth-generation low-loss, high-power IGBT technology. The backup inverter operating mode provides fast switching and precise inverter control to deliver a stable sinusoidal output. High-frequency PWM rectifier charging combined with intelligent battery management prolongs battery service life. The unit handles load steps from 0% to 100% while maintaining stable output. Front-panel indicators show device status; built-in protections and online diagnostics trigger sound and light alarms on fault conditions. Typical applications include building lighting, road traffic lighting, power utilities, and industrial and mining fire emergency systems.
